Suicide bomber kills guard at U.S. embassy in Turkey

ANKARA (Reuters) - A far-leftist suicide bomber killed a Turkish security guard at the U.S. embassy in Ankara on Friday, officials said, blowing open an entrance and sending debris flying through the air.

The attacker detonated explosives strapped to his body after entering an embassy gatehouse. The blast could be heard a mile away. A lower leg and other human remains lay on the street.

Prime Minister Tayyip Erdogan said the bomber was a member of the Revolutionary People's Liberation Party-Front (DHKP-C), a far-left group which is virulently anti-U.S. and anti-NATO and is listed as a terrorist organisation by Washington.

The White House said the suicide attack was an "act of terror" but that the motivation was unclear. U.S. officials said the DHKP-C were the main suspects but did not exclude other possibilities.

Islamist radicals, extreme left-wing groups, ultra-nationalists and Kurdish militants have all carried out attacks in Turkey in the past. There was no claim of responsibility.

"The suicide bomber was ripped apart and one or two citizens from the special security team passed away," said Prime Minister Tayyip Erdogan.

"This event shows that we need to fight together everywhere in the world against these terrorist elements," he said.

In New York, the U.N. Security Council strongly condemned the attack as a heinous act.

Turkish media reports identified the bomber as DHKP-C member Ecevit Sanli, who was involved in attacks on a police station and a military staff college in Istanbul in 1997.

KEY ALLY

Turkey is a key U.S. ally in the Middle East with common interests ranging from energy security to counter-terrorism and has been one of the leading advocates of foreign intervention to end the conflict in neighboring Syria.

Around 400 U.S. soldiers have arrived in Turkey over the past few weeks to operate Patriot anti-missile batteries meant to defend against any spillover of Syria's civil war, part of a NATO deployment due to be fully operational in the coming days.

The DHKP-C was responsible for the assassination of two U.S. military contractors in the early 1990s in protest against the first Gulf War and launched rockets at the U.S. consulate in Istanbul in 1992, according to the U.S. State Department.

Deemed a terrorist organisation by both the United States and Turkey, the DHKP-C has been blamed for suicide attacks in the past, including one in 2001 that killed two police officers and a tourist in Istanbul's central Taksim Square.

The group, formed in 1978, has carried out a series of deadly attacks on police stations in the last six months.

The attack may have come in retaliation for an operation against the DHKP-C last month in which Turkish police detained 85 people. A court subsequently remanded 38 of them in custody over links to the group.

"HUGE EXPLOSION"

U.S. Ambassador Francis Ricciardone emerged through the main gate of the embassy shortly after the explosion to address reporters, flanked by a security detail as a Turkish police helicopter hovered overhead.

"We're very sad of course that we lost one of our Turkish guards at the gate," Ricciardone said, describing the victim as a "hero" and thanking Turkish authorities for a prompt response.

U.S. State Department spokeswoman Victoria Nuland condemned the attack on the checkpoint on the perimeter of the embassy and said several U.S. and Turkish staff were injured by debris.

"The level of security protection at our facility in Ankara ensured that there were not significantly more deaths and injuries than there could have been," she told reporters.

It was the second attack on a U.S. mission in four months. On September 11, 2012, U.S. Ambassador Christopher Stevens and three American personnel were killed in an attack on the U.S. Consulate in Benghazi, Libya.

The attack in Benghazi, blamed on al Qaeda-affiliated militants, sparked a political furore in Washington over accusations that U.S. missions were not adequately safeguarded.

A well-known Turkish journalist, Didem Tuncay, who was on her way in to the embassy to meet Ricciardone when the attack took place, was in a critical condition in hospital.

"It was a huge explosion. I was sitting in my shop when it happened. I saw what looked like a body part on the ground," said travel agent Kamiyar Barnos, whose shop window was shattered around 100 meters away from the blast.

CALL FOR VIGILANCE

The U.S. consulate in Istanbul warned its citizens to be vigilant and to avoid large gatherings, while the British mission in Istanbul called on British businesses to tighten security after what it called a "suspected terrorist attack".

In 2008, Turkish gunmen with suspected links to al Qaeda, opened fire on the U.S. consulate in Istanbul, killing three Turkish policemen. The gunmen died in the subsequent firefight.

The most serious bombings in Turkey occurred in November 2003, when car bombs shattered two synagogues, killing 30 people and wounding 146. Part of the HSBC Bank headquarters was destroyed and the British consulate was damaged in two more explosions that killed 32 people less than a week later. Authorities said those attacks bore the hallmarks of al Qaeda.

Asian shares retreat after China PMI, U.S. payrolls eyed

TOKYO (Reuters) - Asian shares wiped earlier gains on Friday as a tepid Chinese manufacturing report dented sentiment, leaving investors on tenterhooks ahead of U.S. nonfarm payroll data due at 1330 GMT.

China's official purchasing managers' index (PMI) eased to 50.4 in January, the National Bureau of Statistics said on Friday, missing market expectations for a rise and underscoring the fragility of the recovery from the economy's weakest year since 1999.

But a separate private survey showed that growth in China's giant manufacturing sector hit a two-year high in January as domestic demand strengthened, underlining hopes the nation's economic recovery is slowly gaining momentum.

"It seems new orders for exports have declined even when new orders overall rose, suggesting that infrastructure spending and other investment to spur domestic demand is needed to keep (China's) economy growing," said Naohiro Niimura, a partner at research and consulting firm Market Risk Advisory.

"But it's not going to change the view about the Chinese economy recovering. The official data was just neither good nor bad."

The MSCI's broadest index of Asia-Pacific shares outside Japan <.miapj0000pus> slipped 0.2 percent from the morning's 0.2 percent gain.

Australian shares <.axjo> were up 0.6 percent, little changed from before the data came out, drawing support from major mining stocks which gained on a jump in iron ore prices.

But the resources-linked Australian dollar fell 0.2 percent to session lows around $1.040.

With Chinese data news done for the day, investors turned to the U.S. nonfarm payrolls report, which is forecast to show a rise of 160,000 jobs and the unemployment rate to remain steady at 7.8 percent.

U.S. stocks edged lower on Thursday on caution ahead of the jobs report, but the benchmark Standard & Poor's 500 Index <.spx> posted its best monthly gain since October 2011 with a 5.1 percent rise and the best January showing since 1997.

Japan's benchmark Nikkei stock average <.n225> outperformed its Asian peers with a 0.2 percent rise, supported by the yen's decline earlier to fresh lows against major currencies.<.t/>

The dollar steadied around 91.75 yen, having earlier risen as high as 91.87, a level not seen since June 2010. The euro touched 125.05, its highest since May 2010. In January alone, the common currency surged nearly 9 percent on the yen, while the dollar was up more than 5 percent.

Oil and copper prices were higher and the euro remained bid against the dollar, reflecting that jitters was not spreading beyond Asian equities as sentiment has recently been underpinned by falling stress in the euro zone and generally improved data globally.

The euro added 0.3 percent to $1.3613 to the dollar, after earlier reaching a fresh 14-month high of $1.3624. The common currency's strength has pushed the dollar index to a one-month low of 79.107 <.dxy> on Friday.

"The euro revival looks set to continue for some time, as investors return to euro zone bond markets, content with the combination of the European Central Bank backstop for sovereign risk and low inflation danger due to lack of economic growth. The dollar bloc looks to be a key loser in the portfolio reallocation back into EUR," Westpac bank said in a note.

U.S. crude futures inched up 0.1 percent to $97.56 a barrel while Brent rose 0.3 percent to $115.90.

London copper added 0.5 percent to $8,203 a tonne.

Earlier, a private survey showed South Korea's manufacturing sector activity marginally shrank in January after a small rise in December but new export orders grew for the first time in eight months.

Manufacturing purchasing managers' indexes from the United States and the euro zone, as well as the Institute for Supply Management's manufacturing index, are also due later in the session.

SUPER BOWL WATCH: Beyonce, avocados, practice

NEW ORLEANS (AP) — Around Super Bowl XLVII and its host city with journalists from The Associated Press bringing the flavor and details of everything surrounding the game:

GRIDIRON TO LEMONADE STAND

Donald Driver didn't waste much time finding a new job.

The Green Bay Packers all-time leading receiver announced his retirement Thursday morning, then helped kids from Junior Achievement sell lemonade at a pop-up stand in the Super Bowl media center.

Not only did Driver help behind the counter, he loaded up four carrying cases and he and his three new friends set out to find customers. Their cases were empty when they returned.

"All the money they've raised will stay here in New Orleans," Driver said. "What they're starting to do is learn how to run their own business, become entrepreneurs by themselves.

"I'm just here to raise as much money so maybe they can open up their own lemonade stand the next couple of years.

QUICKQUOTE: JERSEYS AND DRUGS

Authorities say buying a cheap imitation NFL jersey may be more harmful than you think.

Kevin Abar, assistant special agent in charge of Homeland Security Investigations in New Mexico, said there's evidence that Mexican drug cartels are getting involved in the counterfeit NFL black market trade because they can make quick money.

"A lot of folks may think that there's nothing wrong with buying a knockoff Denver Broncos jersey, but in reality, the money is being used to fund the drug war in Mexico," Abar said.

STAT OF THE DAY: 158M AVOCADOS

AP Food Editor J.M. Hirsch has the stat of the day today: Americans are expected to consume 158 million avocados around the Super Bowl.

That's 79 million pounds of green goodness — up from 8 million pounds at the turn of the century.

So has the guacamole improved that much? Not really, it's just outstanding marketing and other factors.

YUP, WE HEARD YOU, BEYONCE

Beyonce belted out the national anthem — for real — and America clearly heard.

Shortly after the singer's press conference on Thursday where she admitted singing to a backup track during President Barack Obama's inauguration, "National Anthem" became a trending topic in the United States on Twitter.

Millions of fans clearly approved of her impromptu performance, now reassured that her pipes are still fine.

NO TAPE NEEDED

Beyonce's version of the national anthem was worth the wait.

The superstar singer, roundly criticized for lip syncing "The Star-Spangled Banner" at the inauguration 10 days ago, walked into Thursday's news conference for the Super Bowl halftime show and asked the ballroom filled with several hundred people to stand. She then belted out a spine-tingling version of the anthem, leaving no doubts about the power of her voice. Many in the room applauded when she finished.

"Thank you guys so much. Any questions?" Beyonce said, drawing laughs.

Beyonce admitted she sang along with a pre-recorded track at the inauguration, saying she hadn't had time to rehearse with the orchestra. This was too big of an occasion to have it be anything less than perfect, she said.

"I did not feel comfortable taking a risk," she said. "This was about the president and the inauguration and I wanted to make my country proud."

She did promise to sing live Sunday, however.

"I am well-rehearsed," she said. "This was what I was born to do."

That was about all Beyonce was willing to spill, though. She wouldn't say what she'll be singing, though she did say it was "not easy" to choose a few songs from her many hits.

"All of my songs are like my children," she said.

As for that rumored Destiny's Child reunion, Beyonce wouldn't confirm it.

She didn't deny it, though, either.

"I can't really give you any details," she said. "I'm sorry."

TURF WARS

The Baltimore Ravens don't like the artificial turf at Tulane's baseball field.

So they've moved to the Saints' facility instead.

The San Francisco 49ers were already training at the Saints' complex in nearby Metairie.

The AFC champions were forced to practice in the outfield of the baseball facility Wednesday because Tulane has broken ground on a new football stadium. Coach John Harbaugh, star linebacker Ray Lewis and several other players said it was "hard on the legs."

After the Ravens approached the league about practicing on grass, the NFL arranged for them to follow the 49ers at the Saints training fields.

BEYONCE, BUT WHO ELSE?

There's lots of hype for Beyonce's halftime performance at the Super Bowl, but she's far from the only A-list act in New Orleans this week.

The NFL has announced Jennifer Hudson is planning to sing "America the Beautiful" before the game with the chorus from Sandy Hook Elementary School in Newtown, Conn.

Just add her to the already packed list. It also includes:

— Justin Timberlake, in his first major musical performance in four years (hosting Saturday Night Live doesn't count — he hasn't been an official musical guest on the show since 2006).

— Stevie Wonder

— CeeLo Green with his old hip-hop clique, Goodie Mob.

—Rascal Flatts with Journey.

And then there's the parties. Lil Wayne is throwing a bash. Jay-Z will host another event the night before his wife, Beyonce, takes stage. Jamie Foxx and Santigold are also performing, while DJs including Diplo and Questlove from The Roots are spinning.

Not that it's ever difficult, but it's extra easy to find a party in New Orleans the next few days.

PUTTING POLITICS ASIDE FOR NEW ORLEANS

Long working on opposite sides of the American political spectrum, James Carville and Mary Matalin are pulling in the same direction when it comes to promoting their adopted home of New Orleans as a Super Bowl host.

Carville, a longtime Democratic strategist, and Matalin, a Republican pundit, are the co-chairs of the Super Bowl host committee. They're also married.

They've been making the rounds together from one event to the next in the convention center, which houses both the NFL Experience theme park and work stations for several thousand international media.

Carville is from Louisiana and the couple married in New Orleans. Then in 2008, they decided to move here from Washington, D.C. Now living in a stately home just two blocks off of historic St. Charles Avenue, they've been among the biggest boosters of the Big Easy's recovery from Hurricane Katrina, lending their support to a variety of community projects with goals ranging from restoration of fragile coastal wetlands to education and economic development.

The pair agree that while organizing a Super Bowl doesn't cost as much as a presidential campaign, it's just as hard because it's a multiyear project with a lot of moving parts.

Carville says he's always been a sports fan so the transition was natural for him. Matalin says one obvious goal is to get New Orleans back in the regular rotation as a Super Bowl host, but the larger goal is to help the city's future by demonstrating how successfully it can host one of the biggest single events in the sports world. While New Orleans is hosting its 10th Super Bowl, the NFL championship has not been played there since 2002.

Says Carville: "If it goes the way we hope it does, it'll go beyond economic impact. It'll go beyond who won the game. It think there's something significant that's coming to a point here in the city."

ZOO VS ZOO

File this in the quirky Super Bowl wager department: Zoos in Baltimore and San Francisco are gambling with the homes of two ravens and a rhino.

Leaders of The Maryland Zoo and The San Francisco Zoological Gardens have wagered naming rights to their respective exhibits with ties to their hometown football teams.

The zoo in Baltimore is home to official Ravens mascots, Rise and Conquer. If 49ers win, it will rename the ravens' enclosure the "San Francisco 49ers exhibit."

If the Ravens win, the San Francisco zoo has agreed to re-name the enclosure of its black rhino "Boone," who is named after the 49ers offensive tackle Alex Boone, in honor of the Ravens.

The new name would last one month, starting Feb. 11.

___

CATCHING THE COUNTERFEITERS

Shop wisely when looking for those Super Bowl souvenirs.

Federal officials have seized more than 163,000 counterfeit items worth more than $13.6 million over the last five months as part of Operation Red Zone, John Morton, director of U.S. Immigrations and Customs Enforcement, said. That's a "significant" increase from last year, when about $5 million worth of merchandise was seized.

"Everything from hats to jerseys to Nike shoes. My personal favorite is this counterfeit Super Bowl ring from Super Bowl XLIV," Morton said, holding up a massive gold ring. "It's actually quite heavy and a better counterfeit than most. Just goes to show you the lengths people will go in this business."

Equally troubling are websites selling counterfeit merchandise, some so sophisticated they include anti-virus logos and the seal of the Better Business Bureau — making them almost impossible to tell them apart from legitimate vendors.

Morton said federal officials have already seized domain names of 313 web sites, almost all of which originated overseas.

"Imagine what's going on when you're putting your credit card through this site. Really think about that," Morton said. "The site is being run by overseas criminals in Asia.... You can imagine what the result is, and sadly many, many of these sites come with malware and other unfortunate ornaments on the Christmas tree."

The easiest way to make sure fans are buying legitimate merchandise is to buy from an official vendor, Morton said. Each team has one, as does the NFL.

But the best way fans can prevent being scammed is to use common sense, Morton said. Look closely at items, and there will be signs they're fakes. If there are extra words in a website address — com.us — or misspellings, that's almost always a dead giveaway.

"We're not letting up," Morton said. "We'll have teams out the next couple of days looking for counterfeit and scam artists."

RENO: THE KAEPERNICK EFFECT

Casinos in the Biggest Little City in the World are expecting a bump in Super Bowl betting this year thanks to 49ers quarterback Colin Kaepernick, maybe enough to help Nevada set a record in wagering on the game.

Kaepernick played college football at Nevada, just down the street from casinos in Reno.

Now, most of those casinos are offering an especially large number of proposition bets on the quarterback.

Kaep-mania has run so rampant in Reno that sporting goods stores can't keep stocked in jerseys. More than 7,000 fans set what Nevada officials said was a world record when they all simultaneously kissed their arms "Kaepernicking style" during a break in last week's basketball game against San Diego State.

A Kaepernick viewing party is planned during Sunday's game at the student union.

NO MORE TALKING

The players can focus on football now — they're officially done talking to the media.

Ravens safety Ed Reed was the last guy at the podium on Thursday. After he finished talking with reporters, he scooped up a blue placard with his name on it.

"I'm going to give it to my mother," he said.

He said he's very glad that his interviews are done for the week.

Players had three hourlong sessions during the week, and Reed had another press availability on Monday.

The coaches for the 49ers and Ravens will speak with reporters again on Friday morning.

BROTHERLY ADVICE: BROOK LOPEZ

Baltimore Ravens coach John Harbaugh and San Francisco 49ers coach Jim Harbaugh are hardly the only high-profile siblings who've squared off in their arena of expertise. The AP is asking some others who can relate how they'd handle going against a family member in the Super Bowl.

Brooklyn Nets center Brook Lopez said after scoring 21 points in a loss to the Miami Heat on Wednesday night that it's a combination of joy and competitiveness.

"I know they're just going to treat it as a game. That's how I treat it whenever I play Robin," Brook Lopez said. "I know they will enjoy it as well. But if I have any experience playing against Robin growing up, I know it's going to be competitive. I know they're going to want to beat each other."

Brook's brother, Robin, plays for the New Orleans Hornets.

SORRY, MOM

The way Jack Harbaugh tells the story, Jackie Harbaugh was so shocked by her eldest son's decision to choose coaching over a career in law or politics, she fell face-first into a dish of mashed potatoes.

See, Jackie Harbaugh loves political science and politics. And as a political science major at Bowling Green with a high grade-point, John Harbaugh seemed headed for law school.

"Jackie was so excited about it," Jack Harbaugh said.

But both of the Harbaugh boys had been bitten by the coaching bug early. The practice fields at Iowa and Michigan were their playground, and they knew more about coaching before they got out of grade school than some veteran assistants.

"He came home one day and we're sitting around the table and we're having dinner. Jackie says, 'John, what law school will it be?' John said, 'Mom, I think I want to try coaching,' Jack Harbaugh said. "To which Jackie went facedown into the mashed potatoes. She said, 'What? Coaching? You've got to reconsider!'"

That's not exactly what happened, Jackie Harbaugh said.

"May I tell the truth? There were no mashed potatoes," she said. "When he came home and talked about (coaching) and I saw that look in his eyes, my feeling was, you have to do what you want to do. If you want to try this and see where it takes you, that would be great."

Seems like he made the right choice. After making the playoffs in each of his first four seasons, John Harbaugh has the Baltimore Ravens in the Super Bowl on Sunday, where they'll face his brother Jim's San Francisco 49ers.

EATING RIGHT

How about some home cookin' in the Big Easy — as in 150 plates of it to feed a football team? That's what Ravens wide receiver Jacoby Jones' mother, Emily, presented the Baltimore players for dinner this week at the team hotel to kick off Super Bowl prep New Orleans-style.

"Gumbo, jambalaya, potato salad, bread pudding, macaroni, the whole nine yards. She made 150 plates," Jones said. "All they kept saying is she put her foot in it. I love it."

That's a real compliment around here.

Now, Jones might give his mother a break.

"I'm going to let her be. I might buy me some crawfish or something."

And he knows all the best spots in New Orleans to get it.

New Stroke Guidelines Expand Use of Clot-Busting Drugs

Some people who’ve had a stroke can receive a clot-busting drug up to 4.5 hours after their symptoms begin, according to new guidelines from the American Heart Association.

Previously, the guidelines said the drug must be delivered within three hours of the onset of symptoms.

The drug, called tissue plasminogen activator, or tPA, breaks down blood clots in the brain, and can improve stroke symptoms and reduce the risk of disability. It is used only for strokes caused by blood clots, and not those caused by bleeding in the brain. The sooner the treatment is given, the better a patient’s chances for recovery, said Dr. Edward Jauch, lead author of the guidelines and director of the Division of Emergency Medicine at the Medical University of South Carolina.

Currently, just 3 to 5 percent of stroke patients reach the hospital in time to be considered for the treatment, the AHA says. Researchers hope the new guidelines will increase the number of patients who receive the treatment, Jauch said.

Patients are eligible to receive tPA in the extended time window — 3 to 4.5 hours after stroke symptoms appear — if they are younger than age 80, if their stroke is mild to moderate in severity, if they are not taking anticoagulants (blood thinners), and if they do not have a history of stroke or diabetes, Jauch said.

Another new recommendation says stroke patients eligible for tPA should receive it within one hour of arriving at the hospital.

A 2007 European study showed the benefits of using tPA in the extended time window. In 2009, the AHA issued an advisory to doctors about the benefits of using tPA in the extended window, but this is the first time the recommendation has appeared in the organization’s official stroke management guidelines. 

The new guidelines also recommend that hospitals offering specialized stroke treatment should collaborate with facilities that don’t have such specialized treatments. For instance, the hospitals might set up a network for “telemedicine,” which would allow doctors at special treatment centers to assess a patient remotely via a computer monitor or TV screen. Hospitals also should set up efficient systems that allow stroke patients to be quickly transferred from one hospital to another if needed, Jauch said

Symptoms of stroke include difficulty speaking (slurred speech) or understanding others, arm weakness or numbness, face numbness or drooping, and blurred vision. If you experience these symptoms, you should call 911 right away, the AHA says.

Pass it on: Some stroke patients can now receive a clot-busting drug up to 4.5 hours after the stroke occurs.

Reality check needed on immigration?

STORY HIGHLIGHTS

• Howard Kurtz: The mainstream media are rooting for immigration policy changes


• Kurtz: Is enthusiasm causing the media to overestimate the prospects for reform?


• He says the Republican House has been a graveyard for numerous Obama reforms


• Kurtz: Illegal immigration still arouses visceral opposition among some Americans

Editor's note: Howard Kurtz is the host of CNN's "Reliable Sources" and is Newsweek's Washington bureau chief. He is also a contributor to the website Daily Download.

(CNN) -- The mainstream media -- you know who you are -- are rooting for immigration reform.

They like the idea of doing something to accommodate the country's 11 million undocumented immigrants, who, despite conservative rhetoric to the contrary, were never going to be banished.

They swoon over the kind of bipartisanship that brings together John McCain and Marco Rubio on the one hand and Barack Obama and Chuck Schumer on the other.

Howard Kurtz

They believe the Republican Party needs to moderate its harsh rhetoric about immigrants -- if only to salvage its political future -- and are welcoming the GOP's new realism.

But is that enthusiasm causing media organizations to overestimate the prospects for reform?

Watch: Steve Kroft Plays Defense Over Hillary/Obama Lovefest on '60 Minutes'

Any bill still must pass the Republican House, which has been a graveyard for numerous Obama reforms. The Senate has always been a place where top lawmakers reach across the aisle more easily than in the polarized House, as was evident during the fiscal cliff debacle. And there are conservative groups determined to derail any path toward citizenship, which they view as amnesty.

It's not that journalists are acting as cheerleaders for the emerging plan. But when the media have qualms about an issue, they couch it as being "controversial" and "risky" (say, George W. Bush's plan to privatize Social Security).

Opinion: Immigrant - Can we trust Obama?

By contrast, look at the way the president's immigration speech in Las Vegas was covered:

The New York Times: "Seizing on a groundswell of support for rewriting the nation's immigration laws ..."

The Washington Post: "Obama added to momentum on Capitol Hill in favor of an overhaul of the nation's immigration laws ..."

We saw the same supportive approach when the Pentagon lifted a ban on women serving in front-line combat positions, which, despite some conservative opposition, was greeted with favorable features that largely depicted the move as long overdue.

Watch: Should N.Y. Times Have Censored Company Name Over the S-Word?

As with many perpetual Beltway disputes, the contours of a common-sense compromise on immigration have been clear for some time. The right wants tougher border enforcement and employer verification procedures. The left wants undocumented immigrants taken out of the "shadows," as Obama put it, and given a chance to become openly productive members of society.

The key are the tradeoffs. How long would a path to citizenship take? Are fines and back taxes required? How do we ensure that those who broke the law don't get an unfair advantage over legal applicants?

I don't argue with the standard political analysis that the moment may be ripe for immigration reform.

Watch: Media Seize on Emotional Moment of Gabby Giffords' Testimony

Mitt Romney, who talked about wanting immigrants to "self-deport," got clobbered among Hispanic voters. The GOP has lost the popular vote in five of the past six presidential elections. Sean Hannity, the Fox News commentator, says he has "evolved" on the issue, and he's not alone.

The conservative media may be a bellwether here. After Obama's Tuesday speech, Hannity's leadoff guest was Karl Rove, the former Bush lieutenant who favors the Senate compromise. And when Rubio, the Florida senator and son of Cuban immigrants, called in to Rush Limbaugh's show, the host -- while criticizing Obama -- told him, "What you are doing is admirable and noteworthy. You are recognizing reality."

But illegal immigration remains a divisive subject that still arouses visceral opposition among some Americans. Capitol Hill is a place where partisan maneuvering can push the government to the brink of default. And as George W. Bush learned in his second term, hammering out a compromise on such a volatile issue is maddeningly elusive.

Perhaps the election changed the landscape and both parties will find a way to compromise. In the meantime, it might be wise to take the upbeat media coverage with a healthy dose of skepticism.

Hadiya Pendleton's 'twin' describes death of best friend

The best friend of Hadiya Pendleton talks about the moments before her friend was shot in Chicago on January 31, 2013. (Heather Charles, Chicago Tribune)

As she and her high school classmates fled from the gunfire, Hadiya Pendleton screamed that she had been shot, fell to the ground, struggled to get up and fell again, according to her best friend.

The best friend and another girl scrambled to Pendleton's side, cradling her in their arms as others ran for help.

"I was holding her hand trying to talk her through it," her best friend told the Tribune on Thursday. "I was like, 'You're going to be fine, you're going to be OK.'"

But Hadiya, 15, died shortly after a bullet pierced her back Tuesday, igniting outrage over the senseless loss of another young victim of Chicago's out-of-control gun violence and leaving her friends staggered by the horrifying chain of events on what had been a carefree afternoon.

In the account that follows, the Tribune is not naming those who witnessed the shooting and its aftermath because the gunman is still at large.

On Tuesday afternoon, the mood outside King College Prep in North Kenwood was jubilant. The students at the elite high school had just finished final exams, classes had let out early and the winter weather was spectacular, tipping into the low 60s.

Hadiya and her best friend, both sophomores, headed toward a nearby Potbelly's, one of their favorite places to eat, the friend said. But on their way, at about 1:30 p.m., they ran into friends who invited them to Harsh Park, just a few blocks away from the school.

"We were like, 'OK, sure, who doesn't want to walk around outside when it's nice?'" Hadiya's best friend said.

As they walked, the group of about a dozen teens discussed which tests had been easy and which had been hard. Some were volleyball players from King and others went to another high school, Hadiya's friends said.

Once they reached the small, residential park, Hadiya and others headed to a playground where they swung in the warm air while chatting about their plans for the summer and their 16th birthdays. Hadiya's best friend said she and Hadiya had talked about a joint sweet 16 party and possibly wearing matching gold heels and colorful outfits to celebrate the occasion.

But then a sudden downpour drove the teens beneath a metal awning where Hadiya played "Misery Business" by the band Paramore on her cellphone and others tweeted and texted as they waited out the rain.

Minutes later, however, Hadiya's best friend said she saw a gun-wielding male scale the park fence and approach the group. She yelled a warning to her friends, but the gunman opened fire, spraying the teens with bullets as they ran.

Hadiya was struck in the back about 2:20 p.m. One teen suffered a graze wound to an ankle. And a 17-year-old junior at King was hit in the left leg below the calf, according to his mother, who said he was trying to protect his girlfriend.

The teen's mother said that her son, an Eagle Scout, didn't realize he had been shot. He felt a little sting in his leg before he looked down and saw blood.

A nurse who lived in the area and was leaving her home at the time of the shooting ran to the group, applied a makeshift tourniquet to the teen shot in the leg and called 911. The nurse instructed the others on how to take care of Hadiya.

In the meantime, another friend of Hadiya's ran to a nearby Subway restaurant, burst through the door and asked to borrow a man's phone to call 911.

But by then wailing police cars whizzed by toward the park, so she called her mom.

"I told her to stay put," her mother told the Tribune. "I can't even tell you, as a mother, what it's like to get that phone call. My goal was to get to my child."

The friend said that she and Hadiya met freshman year at a high school dance camp. The friend joined poms, while Hadiya became a majorette, traveling to Washington last month to perform in a competition with her squad during President Barack Obama's inauguration weekend.

The girls were nicknamed "twins" by classmates and teachers because of their similar appearance, the friend said. From haircut to smile to skin tone to personalities, the two were hard to tell apart, she said.

Explosion at Mexican oil giant Pemex headquarters kills 25

MEXICO CITY (Reuters) - A powerful explosion rocked the Mexico City headquarters of state-owned oil giant Pemex on Thursday, killing at least 25 people, injuring more than 100 and trapping others inside.

The mid-afternoon blast in a neighboring building shattered the lower floors of the downtown tower, throwing debris into the streets and sending frightened workers running outside.

A government official, speaking on condition of anonymity, said a preliminary line of investigation was that the blast came from a gas boiler that exploded in the adjacent Pemex building. But the cause was still being determined, the official added.

The explosion at the building complex, where thousands of Pemex employees worked, was the latest in a series of serious safety problems to hit Mexico's national oil monopoly.

Interior Minister Miguel Angel Osorio Chong said the blast killed at least 25 people, injured over 100, and that the number of casualties could rise.

Rescue workers were still searching for employees trapped inside the Pemex skyscraper on Thursday night. At least one person had been rescued alive, Osorio Chong said.

Mauricio Parra, a paramedic at the scene, said that as many as 100 people could be trapped at the offices of Pemex, a national institution that President Enrique Pena Nieto's administration has pledged to reform this year.

Police quickly cordoned off the building, and television images showed the explosion caused major damage to the ground floor and blew out windows on the lower floors of the tower.

"You could feel it all through the building," said Mario Guzman, a Pemex worker who was on the 10th floor of the building, which is more than 50 stories high.

First mistaking the blast for an earthquake, Guzman, who said he escaped after running down the stairs, feared the building would collapse on top of him and his colleagues, "and that we would end up like a sandwich."

Pemex said initially the tower was evacuated due to a problem with its electricity supply. It then said there had been an explosion, but did not say what caused it.

The Pemex blast occurred shortly before many workers were due to end their shifts at the complex.

The company said its business would not be affected by the incident and that it would continue to operate normally.

FORCE OF LAW

Earlier in the evening, Pena Nieto, who took office in December, went to the scene and said the explosion would be thoroughly investigated. He vowed to apply "the force of the law" if anyone was found to be responsible for it.

Mexican media reported that after the blast, security officials carried out a precautionary search of Congress for explosive devices, but found nothing.

Asked about this, Osorio Chong said normal security procedures were being followed, but added that "additional care" was being taken while the blast was being cleared up.

Helicopters buzzed around the building and lines of fire trucks sped to the entrance, while emergency workers ferried injured people through wreckage strewn on the street.

Search-and-rescue dogs were sent into the skyscraper, a Mexico City landmark that sports a distinctive "hat" on top.

Some families of people working in the tower were impatient for news about missing relatives.

Gloria Garcia, 53, herself a Pemex worker who was not in the building during the explosion, came to see if she could track down her son, who worked in one of the floors hit.

"I'm calling his phone and he's not answering," Garcia said, weeping as she called repeatedly on her phone. "Nobody knows anything. They won't let me through. I want to see my son whatever state he's in."

DEADLY ACCIDENTS

Pemex has experienced a number of deadly accidents in recent years and lesser safety problems have been a regular occurrence. In September, 30 people died after an explosion at a Pemex natural gas facility in northern Mexico.

More than 300 were killed when a Pemex natural gas plant on the outskirts of Mexico City exploded in 1984.

Eight years later, about 200 people were killed and 1,500 injured after a series of underground gas explosions in Guadalajara, Mexico's second biggest city. An official investigation found Pemex was partly to blame.

Alberto Islas, a security analyst at consultancy Risk Evaluation, said the explosion at the Pemex offices was another blot against the company's safety record.

"We've seen this time and again at Pemex. They don't have a well-integrated policy," Islas said, noting it would probably take several hours before investigators would be able to determine the cause of the explosion.

Pemex, a symbol of Mexican self-sufficiency since the oil industry was nationalized in 1938, has been held back by inefficiency and corruption and by the burden it shoulders of providing about a third of federal tax revenues.

Pena Nieto has pledged to open up the company to more private investment to improve its performance.

Asian shares off highs, Fed's stance underpins markets

TOKYO (Reuters) - Asian shares took a breather from recent rallies on Thursday though sentiment was underpinned by the U.S. Federal Reserve's pledge to retain its stimulus policy and on signs of stabilization in the euro zone.

Positive economic reports from Asia failed to lift markets as investors continued to assess regional earnings results and ahead of key data such as China's official manufacturing PMI and U.S. monthly nonfarm payrolls on Friday.

The MSCI's broadest index of Asia-Pacific shares outside Japan <.miapj0000pus> fell 0.4 percent after rising 1.3 percent over the past two sessions to nearly an 18-month high. The index was set for a monthly gain of about 2.4 percent.

Australian shares <.axjo> eased 0.4 percent, taking a breather from their 10-day winning streak, the longest in more than nine years, which hoisted local shares to 21-month highs.

"Certainly 2013 has started with an air of optimism. U.S. politicians show some willingness to deal with problems, no fresh issues have emerged in Europe and the Chinese economy is exhibiting firmer growth. Volatility has receded with investors keen to put cash to work in other asset classes," said Craig James, a strategist at CommSec in Sydney.

Southeast Asian stock markets were generally softer but remained near their highs. The Philippines <.psi> hit a record high for the third day running on Wednesday and Thailand's <.seti> market surged to a more than 18-year high on Wednesday.

The Federal Reserve on Wednesday kept in place its monthly $85 billion bond-buying stimulus plan, arguing the support was needed to lower unemployment.

Underscoring the Fed's cautious view, data on Wednesday showed the U.S. economy unexpectedly contracted in the fourth quarter. Still, a lot of that weakness came from a plunge in defense spending, suggesting the underlying fundamentals were not as bad as the headline figures indicated.

In Asia, the data on Thursday provided cause for optimism. Taiwan raised its economic growth forecast for 2013, after the fourth quarter expanded faster than expected and posted its best growth in five quarters on improved demand for the island's electronics exports and stronger consumption.

"Taiwan's economic growth will be better this year as Europe's outlook is becoming positive, it will have a bigger rebound as an export-oriented economy," said Scott Chen, economist at Sinopac Commercial Bank in Taipei.

The Philippines said on Thursday its economy grew 1.5 percent in the December quarter from the previous three months, better than market forecasts.

YEN OFF LOWS

Japan's benchmark Nikkei stock average <.n225> shed 0.6 percent after soaring 2.3 percent to a 33-month high the day before, taking its cue from the yen firming from fresh lows hit on Wednesday. <.t/>

"It's too early to take profit," a trader at a foreign bank said. "People should look for names which are still undervalued, still haven't moved (in line with the rally in the Nikkei) and could outperform."

Prime Minister Shinzo Abe's approach of revitalizing Japan's economy through an aggressive mix of fiscal steps and monetary easing is expected to keep the yen on a weakening path.

The dollar eased 0.3 percent to 90.81 yen after reaching 91.41 yen on Wednesday, its highest since June 2010. The euro also fell 0.3 percent to 123.24 yen, after hitting 123.87 on Wednesday, its peak since May 2010.

Japan's December factory output rose at the fastest pace in a year and a half and firms expect further gains, raising hopes that stabilizing global demand and exports will help pull the economy from its slump.

EUROPE IMPROVING

The euro held near a 14-month high of $1.3588 scaled on Wednesday.

Reports from the euro zone on Wednesday underscored views that the debt crisis-hit region may be overcoming the worst, with economic sentiment improving more than expected across all sectors in January and a gauge for the phase of the business cycle also rising this month.

"The rise in the EUR is a sign of the success of the European Central Bank on the credit front, which matters far more than a short term rise in EUR/USD. Money is flowing into Europe and from North back to the South or from ECB funding to money market funding," Sebastien Galy, strategist at Societe Generale, said in a note to clients.

Spot gold hovered near its one-week high of $1,683.39 an ounce reached on Wednesday.

U.S. crude futures steadied around $97.93 a barrel and Brent crude was up 0.2 percent to $115.09.

Brees wants to bury bounty probe, help New Orleans

NEW ORLEANS (AP) — Drew Brees wore gray sneakers to his first full day of Super Bowl-related appearances — a wise move for an ambassador of a city who had to walk briskly from end to end of a sprawling convention center to make all of his scheduled stops.

Not only was the Saints' star quarterback a man on the move, but also ready to move on from the bitterness of the bounty scandal, which may have undermined his team's chances of playing for a title on its home field.

"We're professionals and we've moved past that in the sense that there's nothing that can be done other than, 'Let's move on and let's find a way to be better next year inspite of it,'" Brees said. "It would be easy to sit here and be angry, but it is what it is."

Coming off a 13-3 campaign in 2011 and a narrow loss to San Francisco in that season's playoffs, the Saints went into the offseason figuring they would be contenders again this season.

Then came the NFL's probe of the Saints' cash-for-hits program and numerous sanctions, the most severe of which was the full-season suspension of coach Sean Payton. New Orleans went 7-9 and missed the playoffs for the first time since 2008, and now the team practicing at the Saints' suburban training center is the NFC champion 49ers.

Throughout the community, displeasure with NFL commissioner Roger Goodell's handling of the matter has been on display for months, from T-shirts reading "Free Payton" (he is now reinstated) to signs in bars and eateries showing Goodell's photo and reading: "Do not serve this man."

During the season, Brees offered his own criticism of what he thought was a faulty investigation and overly heavy-handed disciplinary process. But when the topic came up Wednesday, Brees said it was time to "put this thing to bed."

"We've said what needed to be said," Brees said. "Sean's back, all the pieces are in place, and now it's time for us to put ourselves in a position to make a run."

Brees has been one of New Orleans' most prominent public faces and leading promoters since he arrived in the Big Easy in 2006, when much of the area was still in a state of devastation from Hurricane Katrina's August 2005 landfall. Now his team is the official host of the Super Bowl, and Brees is once again stepping up to highlight his adopted hometown's resurgence as it hosts the Super Bowl for the first time since 2002 — also the first time since Katrina.

He also sought to stamp out the notion that there is some kind of undercurrent of tension between his club, its fans and all of the high-ranking NFL executives in town for the league's biggest single event.

"I know the city is going to be a great host regardless," Brees said. "The city wants to put their best foot forward, they want everybody to have a great experience. I don't like the fact that we've got the NFC team practicing in our facility, but we're going to be gracious hosts and hope that it pays us back in the future."

Brees' stops Wednesday included a talk with area high school kids about the importance of managing one's money. He even revealed that he graduated Purdue with an unpaid $2,000 mobile phone bill, and later regretted it when it damaged his credit score and pushed up the interest rate he had to pay on the first house he bought in San Diego, shortly after being drafted by the Chargers in 2001.

Later, he hosted a news conference in which his foundation donated $1 million to businesses teaming up with charities in the metro area. He also made several radio appearances and lent his support to an event hosted by former Saints special teams standout Steve Gleason, who has the debilitating and incurable neuro-muscular disease ALS.

As an organization, the Saints' approach has mirrored that of their quarterback. Owner Tom Benson spoke at an NFL event promoting the importance of children doing more physical activity on Wednesday. He has invited Goodell to the team party in New Orleans' City Park on Thursday night, and he will attend Goodell's main media event Friday and has even invited the commissioner to watch the game from his suite in the Superdome.

"We're making this the best Super Bowl ever and what that means is we're going to get another Super Bowl to come back in a few years," said Benson with a nod to the city's intent to bid on the 2018 Super Bowl. "We've rolled out the red carpet for everybody."

Frank Supovitz, the NFL's vice president for events, called the Saints "outstanding hosts."

"We've been working on the Super Bowl together with the Saints the last three years. ... The level of partnership has never wavered for a moment," he said. "The NFL and Super Bowl have had a long and deep relationship with the city and with the team and one of the pleasures of my career has been working with the team on the reopening of the dome (after Katrina). We've been very, very close partners with the city and the team and I don't expect that to change."

Dennis Lauscha, who serves as the president of both the Saints and NBA's Hornets — which Benson bought last spring — scoffed at the idea that any animosity lingered between the Saints and the league.

"What we're absolutely concerned about is making sure we put on the best possible show and make a great bid on the next one. We want to put our best foot forward," Lauscha said. "No question we wanted to be the first team to host and play on our own field in the same year. We had an unbelievable experience down in Miami when we won the Super Bowl and we kept on saying how great it would be if we could do that back in New Orleans for our fans, so there is a bit of disappointment in that, but look, we're looking forward to next year and winning the Super Bowl in New York."

NASA launches communication satellite

CAPE CANAVERAL, Fla. (AP) — NASA launched a new communication satellite Wednesday to stay in touch with its space station astronauts and relay more Hubble telescope images.

An unmanned Atlas V rocket blasted into the starry night sky carrying the Tracking and Data Relay Satellite.

This is the 11th TDRS satellite to be launched by NASA. The space agency uses the orbiting network to communicate with astronauts living on the International Space Station.

The first TDRS spacecraft flew in 1983; it recently was retired along with No. 4. The second was lost aboard space shuttle Challenger in 1986; Monday marked the 27th anniversary of the launch disaster.

This newest third-generation TDRS carries the letter K designation. Once it begins working, it will become TDRS-11. It will take two weeks for the satellite to reach its intended 22,300-mile-high orbit. Testing will last a few months.

NASA estimates the satellite costs between $ 350 million and $ 400 million.

Another TDRS spacecraft, L in the series, will be launched next year.

NASA wants at least seven TDRS satellites working in orbit at any one time. The one launched Wednesday will make eight.
