Iran hedges on nuclear talks with six powers or U.S.

MUNICH (Reuters) - Iran said on Sunday it was open to a U.S. offer of direct talks on its nuclear program and that six world powers had suggested a new round of nuclear negotiations this month, but without committing itself to either proposal.

Diplomatic efforts to resolve a dispute over Iran's nuclear program, which Tehran says is peaceful but the West suspects is intended to give Iran the capability to build a nuclear bomb, have been all but deadlocked for years, while Iran has continued to announce advances in the program.

Iranian Foreign Minister Ali Akbar Salehi said a suggestion on Saturday by U.S. Vice President Joe Biden that Washington was ready for direct talks with Iran if Tehran was serious about negotiations was a "step forward".

"We take these statements with positive consideration. I think this is a step forward but ... each time we have come and negotiated it was the other side unfortunately who did not heed ... its commitment," Salehi said at the Munich Security Conference where Biden made his overture a day earlier.

He also complained to Iran's English-language Press TV of "other contradictory signals", pointing to the rhetoric of "keeping all options on the table" used by U.S. officials to indicate they are willing to use force to keep Iran from obtaining a nuclear weapon.

"This does not go along with this gesture (of talks) so we will have to wait a little bit longer and see if they are really faithful this time," Salehi said.

Iran is under a tightening web of sanctions. Israel has also hinted it may strike if diplomacy and international sanctions fail to curb Iran's nuclear drive.

In Washington, Army General Martin Dempsey, the top U.S. military officer, said in an interview broadcast on Sunday that the United States has the capability to stop any Iranian effort to build nuclear weapons, but Iranian "intentions have to be influenced through other means."

Dempsey, chairman of the Joint Chiefs of Staff, made his comments on NBC's program "Meet the Press," speaking alongside outgoing Defense Secretary Leon Panetta.

Panetta said current U.S. intelligence indicated that Iranian leaders have not made a decision to proceed with the development of a nuclear weapon.

"But every indication is they want to continue to increase their nuclear capability," he said. "And that's a concern. And that's what we're asking them to stop doing."

The new U.S. secretary of state, John Kerry, has said he will give diplomacy every chance of solving the Iran standoff.

THE BEST CHANCE

With six-power talks making little progress, some experts say talks between Tehran and Washington could be the best chance, perhaps after Iran has elected a new president in June.

Negotiations between Iran and the six powers - Russia, China, the United States, Britain, France and Germany - have been deadlocked since a meeting last June.

EU officials have accused Iran of dragging its feet in weeks of haggling over the date and venue for new talks.

Salehi said he had "good news", having heard that the six powers would meet in Kazakhstan on February 25.

A spokesman for EU foreign policy chief Catherine Ashton, who coordinates the efforts of the six powers, confirmed that she had proposed talks in the week of February 25 but noted that Iran had not yet accepted.

Kazakhstan said it was ready to host the talks in either Astana or Almaty.

Salehi said Iran had "never pulled back" from the stuttering negotiations with the six powers. "We still are very hopeful. There are two packages, one package from Iran with five steps and the other package from the (six powers) with three steps."

Iran raised international concern last week by announcing plans to install and operate advanced uranium enrichment machines. The EU said the move, potentially shortening the path to weapons-grade material, could deepen doubts about the peaceful nature of Iran's nuclear program.

Prime Minister Benjamin Netanyahu said on Sunday that Israel's mission to stop its arch-enemy from acquiring nuclear weapons was "becoming more complex, since the Iranians are equipping themselves with cutting-edge centrifuges that shorten the time of (uranium) enrichment".

"We must not accept this process," said Netanyahu, who is trying to form a new government after winning an election last month. Israel is generally believed to be the only country in the Middle East with nuclear weapons.

S-League go topless to promote 2013 season

SINGAPORE: Topless - that's how some S-League players were spotted at Orchard Road on Sunday.

The bare-bodied manoeuvre was a publicity stunt for the 2013 S-League season, which kicks off later this month.

The 10 players were not completely naked from the waist up though; their bodies were painted in their respective team strip.

Joining them was S-League CEO Lim Chin, who was game enough to market the league in the bold and rather bare fashion.

Accompanied by fans, the entourage walked down Singapore's famous shopping district distributing flyers.

The approach was a departure from the usual carnivals held by organisers to connect with potential supporters, giving new meaning to 'meeting your heroes in the flesh'.

"I want the players to be involved ... We wanted to something to show… that we really want to reach out to the public, from the players right down to the kit man, to myself," said Mr Lim.

The 2013 season kicks off with the Charity Shield on 15 February, where defending champions Tampines Rovers will take on League Cup winners the Warriors at Jalan Besar Stadium.

How can Amy Poehler help Best Buy during the Super Bowl?

Can she help?

(Credit:
Best Buy/YouTube Screenshot by Chris Matyszczyk/CNET)

In the first quarter of today's Big Game featuring big people doing big things to each other, Amy Poehler will be trying to do big things for Best Buy.

Unlike the players -- who will probably be tied 3-3 in a dull defensive battle when Amy appears -- Poehler has one shot to give the Best Buy brand a shot in arm. Or perhaps a shot at redemption.

Best Buy has been crossing some turbulent oceans recently, so securing the services of one of America' funniest actors is a pleasant coup.

The company has released a sneak preview (embedded here) of Poehler asking questions that are sweetly self-referential, so it may be that this theme will continue during today's spot.

More Technically Incorrect

The idea seems to be that whatever questions you have, those nice people in blue polo shirts will have the answer for you.

In order to reinforce this dream, Best Buy has co-opted the hashtag #infiniteanswers on Twitter.

Naturally, there have already been slight setbacks with this strategy.

For example, a twitterer called Jonathan has already offered: "#infiniteanswers not at your Willimar MN location I have seen smarter things come out of a dead animal."

Worse, another tweeter, Billy Byler seemed to be experiencing a little humorous bile: "Every answer was 'Not sure. Check Amazon.' @BestBuy: Amy Poehler visited us & had A LOT of questions. http://youtu.be/PcmW8HCuLo8 #infiniteanswers."

Can you win them over, Amy? Can you?

Israel suggests responsibility for Syria strike

MUNICH Israel's defense minister indicated Sunday that his country was behind the airstrike on Syria last week, in the first public comments from his government on the attack that U.S. officials said targeted a convoy carrying anti-aircraft weapons bound for the militant group Hezbollah in neighboring Lebanon.

Israeli Defense Minister Ehud Barak brought the issue up at a gathering of the world's top diplomats and defense officials in Germany, initially saying: "I cannot add anything to what you have read in the newspapers about what happened in Syria several days ago."

But, addressing the audience in English, he then added: "I keep telling frankly that we said — and that's proof when we said something we mean it- we say that we don't think it should be allowed to bring advanced weapons systems into Lebanon."

In Syria, President Bashar Assad said his military was capable of confronting any "aggression" targeting the country, his first comments since the airstrike.

Syrian state television said Assad spoke during a meeting with visiting top Iranian official, Saeed Jalili.

Assad also accused Israel of trying to "destabilize" his country at the meeting, BBC reports.

Assad said Syria is capable of facing current challenges and can "confront any aggression" that would target the Syrian people.

Israeli planes hit Syrian target

Israel had not previously commented on the strike, but in the days ahead of the attack, Israeli Prime Minister Benjamin Netanyahu and other top officials repeatedly warned of the dangers of Syrian weapons falling into the hands of Hezbollah and other hostile elements in the region.

The Syrian military, meanwhile, said the target of Israeli jets was a scientific research center. The facility is in the area of Jamraya, northwest of Damascus.

Purported images of the targeted site, aired by Syrian state television on Saturday, show destroyed cars, trucks and military vehicles. A building has broken widows and damaged interiors, but no major structural damage.

Following the attack, Syria's ambassador to Lebanon, Ali Abdul-Karim Ali, said Damascus "has the option and the capacity to surprise in retaliation," but that it was up to the relevant authorities to choose the time and place.

Meanwhile, Syrian opposition leaders and rebels on Friday slammed Assad for not responding to the airstrike, calling it proof of his weakness and acquiescence to the Jewish State.

The chief of Iran's powerful Revolutionary Guards said in remarks Sunday that Tehran also hopes Syria will retaliate against Israel for a recent airstrike on its territory.

The report by the official IRNA news agency quotes Gen. Mohammad Ali Jafari as saying, "We are hopeful that Syria gives an appropriate response to the strike in the proper time."

Since the outbreak of the Syrian civil war, Israeli leaders have repeatedly expressed fears that if Syria were to disintegrate, President Bashar Assad could lose control of his chemical weapons and other arms.

On Saturday night, Netanyahu, who is in the process of forming a new ruling coalition, said his new government would have to deal with weapons "being stockpiled near us and threatening our cities and civilians" — an apparent reference to the deteriorating situation in Syria.

Barak said "Hezbollah from Lebanon and the Iranians are the only allies that Assad has left."

He said in his view Assad's fall "is coming imminently" and when it happens, "this will be a major blow to the Iranians and Hezbollah."

"I think that they will pay the price," he said.

Former SEAL Killed at Gun Range; Suspect Arrested

A former Marine has been charged with three counts of murder in the killing of former Navy SEAL and "American Sniper" author Chris Kyle, the most deadly sniper in U.S. history, and another man at an Erath County, Texas, gun range, police said.

"We have lost more than we can replace. Chris was a patriot, a great father, and a true supporter of this country and its ideals. This is a tragedy for all of us. I send my deepest prayers and thoughts to his wife and two children," Scott McEwen, co-author of "American Sniper: The Autobiography of the Most Lethal Sniper in U.S. Military History," said in a statement to ABC News.

Remembering Kyle for the number of Iraqi insurgents he killed misstates his legacy, McEwen said.

"His legacy is not one of being the most lethal sniper in United States history," McEwen said. In my opinion, his legacy is one of saving lives in a very difficult situation where Americans where going to be killed if he was not able to do his job."

Kyle and a neighbor of his were shot at a gun range in Glen Rose while helping a former Marine who was recovering from post traumatic stress syndrome, ABC affiliate WFAA-TV in Dallas reported.

The suspect, identified as Eddie Ray Routh, 25, was arrested in Lancaster, Texas, after a brief police chase, a Lancaster Police Department dispatcher told ABC News. Routh was driving Kyle's truck at the time of his arrest, police said.

Routh was arraigned Saturday evening on one count of capital murder and two counts of murder. He was brought to the Erath County Jail this morning and was being held there today on a combined $3 million bond, Officer Kyle Roberts said.

Investigators told WFAA that Routh is a former Marine said to suffer from post-traumatic stress syndrome.

Kyle helped found a nonprofit that provides at-home fitness equipment for emotionally and physically wounded veterans, but the director of the foundation said Kyle and Routh had not met through the organization.

"Chris was literally the type of guy if you were a veteran and needed help he'd help you," Travis Cox, the director of FITCO Cares, told The Associated Press. "And from my understanding that's what happened here. I don't know how he came in contact with this gentleman, but I do know that it was not through the foundation."

Authorities identified the other man who was killed with Kyle as 35-year-old Chad Littlefield, who Cox said was Kyle's neighbor and friend.

Kyle, 38, served four tours in Iraq and was awarded two Silver Stars, five Bronze Stars with Valor, two Navy and Marine Corps Achievement Medals, and one Navy and Marine Corps Commendation.

From 1999 to 2009, Kyle recorded more than 150 sniper kills, the most in U.S. military history.

After leaving combat duty, Kyle became chief instructor training Naval Special Warfare Sniper and Counter-Sniper teams, and he authored the Naval Special Warfare Sniper Doctrine, the first Navy SEAL sniper manual. He left the Navy in 2009.

"American Sniper," which was published last year by William Morrow, became a New York Times best seller.

NASA marks 10th anniversary of Columbia disaster

In an emotional memorial service, the widow of the shuttle Columbia's commander recalled their last meeting the day before launch and the devastation the families felt when they learned their loved ones had perished during re-entry 10 years ago Friday.

Speaking in front of the Space Mirror Memorial to fallen astronauts at the Kennedy Space Center's visitor complex, Evelyn Husband-Thompson shared memories of Columbia commander Rick Husband and his six crewmates, saying how proud the families were of the crew's accomplishments during their 16-day science mission.

The night before landing, the families "shared a meal together at a local restaurant," she said. "I went to bed with the NASA (television) channel left on quietly in the background and I fell asleep, thanking God for the great mission, and I was so excited for the reunion with my husband."

Instead, the families listened in disbelief at the shuttle's 3-mile-long runway the next morning as it became clear Columbia had suffered a catastrophic failure during re-entry.

"February 1, 2003, became a traumatic, shocking day," Husband-Thompson said. "Anticipating a joyful homecoming of our crew, we were jolted in the viewing area into a nightmarish stroll of fear, uncertainty, and horror that led to a crushing announcement that the crew had perished during re-entry.

"Words of sorrow, efforts to comfort, even fathoming the magnitude of loss was overwhelming that day. Looks of disbelief from one family member to another brought little comfort. The shock was so intense that even tears were not freely able to fall. They would come in the weeks, months, and years to follow, in waves and in buckets."

And in the months and years that followed, she said, "the human spirit, created by God, began to minister to my family."

"Friends and family cared for us, and countless thousands of others prayed for us. To all of you, I want to say thank you.... God bless the families of STS-107. May our broken hearts continue to heal and may beauty continue to replace the ashes. God bless you."

In an interview before the ceremony, Husband-Thompson said she remains a strong supporter of NASA and the manned space program.

"NASA's an amazing group of folks and they have been hugely supportive of us," she said. "It was Rick's dream since he was 4 years old, and obviously what happened was devastating. But it doesn't stop the cause of space exploration. I totally support it. It's contributed so much to our world."

Several hundred space managers, engineers, and acquaintances gathered to mark the 10th anniversary of the Columbia disaster, the 27th anniversary of Challenger's loss on Jan. 28, 1986, and the 46th anniversary of a launch pad fire on Jan. 27, 1967, that killed three Apollo astronauts.

Their names are carved in the Space Mirror Memorial, along with others who lost their lives in the pursuit of spaceflight.

Columbia was destroyed during re-entry when hot gas penetrated the shuttle's left wing through a hole in a leading edge heat shield panel. The hole was caused by the impact of foam insulation that fell from the ship's external tank during launch 16 days earlier.

As a postaccident investigation would show, NASA had a long history of problems with "foam shedding," but continued to launch shuttles without a thorough understanding of the implications.

"In looking back, there was no malicious intent by any engineer or manager in the decisions they made that led to the loss of Columbia and her crew," said Kennedy Space Center Director Robert Cabana, a veteran shuttle commander. "They were doing their very best to be successful. But we are human and oftentimes, when lacking sufficient data, we make poor decisions. And that results in events like Apollo 1, Challenger, and Columbia."

Cabana said NASA had learned from its mistakes "and we are going on to even greater accomplishments."

"But we must never forget the hard lessons that we learned in the past," he told the crowd. "It's important that we pause to remember and reflect. We must do our very best to prevent something like that from ever happening again. Too much is at stake."

William Gerstenmaier, director of manned space operations at NASA Headquarters in Washington, echoed Cabana's sentiments, saying the Columbia accident "wasn't caused by a single event or a single person, but by a series of technical and cultural missteps stemming all the way back to the first shuttle launch in 1981 when ice and foam first struck the (orbiter)."

"This was a first indication we had a design problem," he said. "But we continued to fly without fully investigating the consequences of foam hitting the orbiter. We continued to lose foam on many missions and this reinforced the idea that all was well. We did not stay hungry, and we didn't deeply analyze the implications of foam being released at precisely the wrong moment."

He cautioned engineers to stay vigilant, to "recognize even the smallest potential flaw can become a big problem."

"In honor of the Columbia crew, it is our job to be aware of the technical subtleties and be creative about understanding them and the underlying problems," he said. "Even small problems can surface as major failures."

At the conclusion of the memorial ceremony, three NASA T-38 jets roared overhead in a "missing man" formation. Gospel singer BeBe Winans performed his song "Ultimate Sacrifice," and Husband-Thompson, assisted by Gerstenmaier, Cabana, and Eileen Collins, commander of the first post-Columbia shuttle mission, placed a wreath at the base of the Space Mirror.

Clinton's legacy: Smart power, celebrity status

(CBS News) After four years as secretary of state, Hillary Clinton was officially replaced by Sen. John Kerry Friday. An improbable pick after a tough primary battle with Barack Obama back in 2008, Clinton has used her celebrity status around the world to make changes both at home and abroad.

John Kerry sworn in as secretary of state

In a heartfelt goodbye to thousands of State Department employees Friday, Clinton said, "I am proud to have been secretary of state. I leave this department confident, confident about the direction we have set."

Friends and colleagues say there's a side to Clinton many people don't know. CBS News correspondent Margaret Brennan talked to those people about Clinton and the legacy she's leaving behind.

She's not a typical Secretary of State saying goodbye. Anne Marie Slaughter, a former Clinton adviser said, "The first trip I took with her was like traveling with Madonna."

At times, Clinton's celebrity has overshadowed her diplomacy. But Slaughter said it shouldn't. "She elevated the roll of development. She's elevated social media, all sorts of new ways to reach people, ways of engaging youth, women, entrepreneurs."

Those tools are what Clinton calls "smart power" - finding ways to connect with people so that they then are able to influence their governments. She's said her extensive travel to 112 countries helped to build goodwill.

Others dismiss it as a vanity project. Critics also complain that she did not craft a clear policy to stop the war in Syria and point to security failures at the U.S. Consulate in Benghazi, Libya.

However, longtime aide Philippe Reines disagrees. "For the last four years she has been, you know, working, literally killing herself for her country," he said.

He said her outreach made it possible to levy sanctions on Iran, North Korea, and to broker the November cease fire in Gaza. Reines has been aboard Clinton's plane for nearly every one of the almost one million miles she flew as secretary of state.

He told CBS News that most people don't know that how normal Clinton is. "I mean, she likes and dislikes a lot of the same things that you and I don't like or do like," he said.

He also said that she's not caught up on her future. "She does not sit around and do that as much as people think she does. It's more sitting around thinking, I saw 'Argo' and that's a great movie, did you see 'Argo?'"

Clinton is reluctant to make any decision yet about running for president in 2016. At a global town hall for students at the Newseum in Washington, Clinton talked about a bid for the presidency.

"I am not thinking about anything like that right now. I am looking forward to finishing up my tenure as secretary of state and then catching up on about 20 years of sleep deprivation," she said.

But few believe she'll stop working, and if you want to know what she'll do, aides say, look at what she's done.

Obama Clings to Shotgun in WH Photo

(Official White House Photo by Pete Souza)

After a week of speculation over the authenticity of claims by President Obama that he regularly participated in skeet shooting at Camp David, the White House released a photograph today showing him firing a shotgun.

The photo shows Obama targeting clay pigeons at the presidential retreat last August, according to the White House. In an interview published Sunday the president said he shoots skeet “all the time” during stays at the compound. The comment was a response to a question of whether he had ever held a gun.

“Not the girls, but oftentimes guests of mine go up there. And I have a profound respect for the traditions of hunting that trace back in this country for generations. And I think those who dismiss that out of hand make a big mistake,” he said.

READ: Skeet-Shooter Obama Has ‘Respect’ for Hunters

But amid a White House-backed push for stronger gun-control in the U.S., some questioned whether the claim was an embellishment or even true. Politicians who regularly use firearms often advertise the fact to gun owners, but ABC News has not found a quote from Obama referencing his own use before the statement on Sunday.

“If he is a skeet shooter, why have we not heard of this?” asked Rep. Marsha Blackburn, R-Tenn. “Why have we not seen photos? Why has he not referenced it at any point in time as we have had this gun debate that is ongoing?”

PHOTOS: From 2009 to Now: Obama Since His First Inauguration

Appearing on CNN this week, the congresswoman challenged Obama to a skeet shooting contest.

The Associated Press reported in 2010 a second-hand reference to the activity. After a visit with the Texas Christian University rifle team, a student reportedly told the AP that Obama told her he’d practiced shooting with the Secret Service.

This the only known image of Obama holding a gun.

Asked Monday about the president’s interview, Press Secretary Jay Carney responded to reporters about how often the president participates in shooting.

“I would refer you simply to his comments,” he said. “I don’t know how often. He does go to Camp David with some regularity, but I’m not sure how often he’s done that.”"

On Wednesday, Carney addressed the issue again, telling press that when the president travels to “Camp David, he goes to spend time with his family and friends and relax, not to produce photographs.”

White House officials and some Obama supporters have compared skeet-doubters to “skeeters” or “birthers,” the label fixed to those who deny Obama was born on U.S. soil in his home state of Hawaii, and therefore is ineligible for the Oval Office.

“Attn skeet birthers. Make our day — let the photoshop conspiracies begin!” senior adviser David Plouffe wrote on Twitter this morning, referencing the popular photo-editing software.

In January, Obama signed several executive orders strengthening gun regulation and revealed proposals that, if enacted, would include bans on assault weapons and high capacity magazines. The move began in response to the December mass-shooting of 20 first graders and six adults at a Newtown, Conn., elementary school.

INFOGRAPHIC: Guns in America: By The Numbers

A recent ABC News/Washington Post poll found 53 percent of Americans viewed Obama’s gun control plan favorably, 41 percent unfavorably.

The photo’s release comes two days before Obama travels to Minneapolis for a speech continuing his push for tougher gun control, where he is expected to appear alongside local law enforcement officials.

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.

Interior Minister Muammer Guler said the bomber was a member of an illegal far-left group. The White House said the suicide attack was an "act of terror", but the motivation was unclear.

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, who was attending a ceremony in Istanbul when the blast happened.

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

Turkish media reports identified the bomber as Ecevit Sanli, a member of the Revolutionary People's Liberation Party-Front (DHKP-C) leftist group, who was involved in attacks on a police station and a military staff college in Istanbul in 1997.

The DHKP-C opposes what it sees as U.S. influence over Turkish foreign policy.

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.

"HUGE EXPLOSION"

U.S. Ambassador Francis Ricciardone emerged through the main gate of the embassy, which is surrounded by high walls, 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.

A U.S. national security source said U.S. officials believed the incident was a suicide bombing but said security measures had worked properly, in that the attacker was not able to get past the outer perimeter of the compound and neither the embassy buildings were damaged, nor were U.S. personnel injured.

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.

OPPOSED TO U.S. INFLUENCE

The DHKP-C, deemed a terrorist organization by both the United States and Turkey, 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.

Guler said the bomber could have been from the DHKP-C which has carried out a series of deadly attacks on police stations in the last six months, or a similar group.

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.

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.
