Turkey: U.S. Embassy bomber known for terror ties

Updated at 4:35 p.m. ET

ANKARA, Turkey The suicide bomber who struck the U.S. Embassy in Ankara spent several years in prison on terrorism charges but was released on probation after being diagnosed with a hunger strike-related brain disorder, officials said Saturday.

The bomber, identified as 40-year-old leftist militant Ecevit Sanli, killed himself and a Turkish security guard on Friday, in what U.S. officials said was a terrorist attack. Sanli was armed with enough TNT to blow up a two-story building and also detonated a hand grenade, officials said.

Turkish Prime Minister Recep Tayyip Erdogan said Friday that police believe the bomber was connected to his nation's outlawed leftist militant group Revolutionary People's Liberation Party-Front, or DHKP-C. And on Saturday DHKP-C claimed responsibility for the attack in a statement posted on a website linked to the group. It said Sanli carried out the act of "self-sacrifice" on behalf of the group.

The authenticity of the website was confirmed to The Associated Press by a government terrorism expert who spoke on condition of anonymity in line with rules that bar government employees from speaking to reporters without prior authorization.

State Dept. had bomber of U.S. embassy in Turkey on terror list

CBS News correspondent Holly Williams reports from Ankara that the DHKP-C is on the State Department's list of terror organizations. They are Marxists who believe that the United States is an imperialist state that's controlling Turkey. Their targets have included both the U.S. and the Turkish military.

Turkey's private NTV television, meanwhile, said police detained three people on Saturday who may be connected to the U.S. Embassy attack during operations in Ankara and Istanbul. Two of the suspects were being questioned by police in Ankara, while the third was taken into custody in Istanbul and was being brought to Ankara.

NTV, citing unidentified security sources, said one of the suspects is a man whose identity Sanli allegedly used to enter Turkey illegally, while the second was suspected of forging identity papers. There was no information about the third suspect.

Earlier, Turkish Interior Minister Muammer Guler said Sanli had fled Turkey after he was released from jail in 2001, but managed to return to the country "illegally," using a fake ID. It was not clear how long before the attack he had returned to Turkey.

NTV said he is believed to have come to Turkey from Germany, crossing into Turkey from Greece. Police officials in Ankara could not immediately be reached for comment.

DHKP-C has claimed responsibility for assassinations and bombings since the 1970s, but it has been relatively quiet in recent years. Compared to al Qaeda, it has not been seen as a strong terrorist threat.

Sanli's motives remained unclear. But some Turkish government officials have linked the attack to the arrest last month of dozens of suspected members of the DHKP-C group in a nationwide sweep.

Speculation also has abounded that the bombing was related to the perceived support of the U.S. for Turkey's harsh criticism of the regime in Syria, whose brutal civil war has forced tens of thousands of Syrian refugees to seek shelter in Turkey. But Erdogan has denied that.

Officials said Sanli was arrested in 1997 for alleged involvement in attacks on Istanbul's police headquarters and a military guesthouse, and jailed on charges of membership in the DHKP-C group.

While in prison awaiting trial, he took part in a major hunger strike that led to the deaths of dozens of inmates, according to a statement from the Ankara governor's office. The protesters opposed a maximum-security system in which prisoners were held in small cells instead of large wards.

Sanli was diagnosed with Wernicke-Korsakoff syndrome and released on probation in 2001, following the introduction of legislation that allowed hunger strikers with the disorder to get appropriate treatment. The syndrome is a malnutrition-related brain illness that affects vision, muscle coordination and memory, and that can cause hallucinations.

Sanli fled Turkey after his release and was wanted by Turkish authorities. He was convicted in absentia in 2002 for belonging to a terrorist group and attempting to overthrow the government.

On Saturday, the U.S. flag at the embassy in Ankara flew at half-staff and already tight security was increased. Police sealed off a street in front of the security checkpoint where the explosion knocked a door off its hinges and littered the road with debris. Police vehicles were parked in streets surrounding the building.

The Ankara governor's office, citing the findings of a bomb squad that inspected the site, said Sanli had used 13.2 pounds of TNT for the suicide attack and also detonated a hand grenade. That amount of TNT can demolish "a two-story reinforced building," according to Nihat Ali Ozcan, a terrorism expert at the Ankara-based Economic Policy Research Foundation of Turkey.

Officials had earlier said that the bomber detonated a suicide vest at the checkpoint on the outer perimeter of the compound.

The guard who was killed was standing outside the checkpoint. The U.S. ambassador on Saturday attended his funeral in a town just outside of Ankara.

A Turkish TV journalist was seriously wounded and two other guards had lighter wounds.

DHKP-C's forerunner, Devrimci Sol, or Revolutionary Left, was formed in 1978 as a Marxist group openly opposed to the United States and NATO. It has attacked Turkish, U.S. and other foreign targets since then, including two U.S. military contractors and a U.S. Air Force officer.

The group changed its name to DHKP-C in 1994.

Friday's attack came as NATO deployed six Patriot anti-missile systems to protect its ally Turkey from a possible spillover from the civil war raging across the border in Syria. The U.S., Netherlands and Germany are each providing two Patriot batteries.

Ozcan, the terrorism expert, said the Syrian regime, which had backed terrorist groups in Turkey, including autonomy-seeking Kurdish rebels, during the Cold War era and through the 1990s, had recently revived ties with these groups.

As Turkey began to support the Syrian opposition, Syrian President Bashar Assad's regime began to try "rebuilding its ties with these organizations," Ozcan said.

Radikal newspaper reported that the DHKP-C had recently been taking an interest in "regional issues," reviving its anti-American stance and taking on "a more pro-Assad position."

Former U.S. ambassador to Turkey Ross Wilson speculated that the masterminds of the embassy bombing may have been partly motivated by U.S.-Turkish policy on Syria.

"A successful attack would embarrass the Turkish government and security forces, and it would have struck at the United States, which is widely — if wrongly — thought to have manipulated the Erdogan government into breaking with Bashar al-Assad and supporting efforts to remove him from power," Wilson, director of the Dinu Patriciu Eurasia Center at the Washington-based Atlantic Council, wrote in an analysis. "That might rekindle public support for the group. Alas for DHPK/C, this seems unlikely."

Howard Eissenstat, a Turkey expert at St. Lawrence University in the United States, said the bombing showed that a "relatively isolated and obscure group" still has the capacity to cause havoc.

"They really fall outside of our comfortable narratives," Eissenstat wrote in an email to The Associated Press. "And they do seem to have been left in an ideological time warp. There is something distinctly cult-like about them."

The attack drew quick condemnation from Turkey, the U.S., Britain and other nations, and officials from both Turkey and the U.S. pledged to work together to fight terrorism.

It was the second deadly assault on a U.S. diplomatic post in five months.

On Sept. 11, 2012, terrorists attacked a U.S. mission in Benghazi, Libya, killing U.S. Ambassador Chris Stevens and three other Americans. The attackers in Libya were suspected to have ties to Islamist extremists, and one is in custody in Egypt.

U.S. diplomatic facilities in Turkey have been targeted previously by terrorists. In 2008, an attack blamed on al Qaeda-affiliated militants outside the U.S. Consulate in Istanbul left three assailants and three policemen dead.

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.

PHOTOS: Presidents and Their Guns

“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 is 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.

Turkey says tests confirm leftist bombed U.S. embassy

ISTANBUL (Reuters) - A member of a Turkish leftist group that accuses Washington of using Turkey as its "slave" carried out a suicide bomb attack on the U.S. embassy, the Ankara governor's office cited DNA tests as showing on Saturday.

Ecevit Sanli, a member of the leftist Revolutionary People's Liberation Army-Front (DHKP-C), blew himself up in a perimeter gatehouse on Friday as he tried to enter the embassy, also killing a Turkish security guard.

The DHKP-C, virulently anti-American and listed as a terrorist organization by the United States and Turkey, claimed responsibility in a statement on the internet in which it said Turkish Prime Minister Tayyip Erdogan was a U.S. "puppet".

"Murderer America! You will not run away from people's rage," the statement on "The People's Cry" website said, next to a picture of Sanli wearing a black beret and military-style clothes and with an explosives belt around his waist.

It warned Erdogan that he too was a target.

Turkey is an important U.S. ally in the Middle East with common interests ranging from energy security to counter-terrorism. Leftist groups including the DHKP-C strongly oppose what they see as imperialist U.S. influence over their nation.

DNA tests confirmed that Sanli was the bomber, the Ankara governor's office said. It said he had fled Turkey a decade ago and was wanted by the authorities.

Born in 1973 in the Black Sea port city of Ordu, Sanli was jailed in 1997 for attacks on a police station and a military staff college in Istanbul, but his sentence was deferred after he fell sick during a hunger strike. He was never re-jailed.

Condemned to life in prison in 2002, he fled the country a year later, officials said. Interior Minister Muammer Guler said he had re-entered Turkey using false documents.

Erdogan, who said hours after the attack that the DHKP-C were responsible, met his interior and foreign ministers as well as the head of the army and state security service in Istanbul on Saturday to discuss the bombing.

Three people were detained in Istanbul and Ankara in connection with the attack, state broadcaster TRT said.

The White House condemned the bombing as an "act of terror", while the U.N. Security Council described it as a heinous act. U.S. officials said on Friday 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.

SYRIA

The DHKP-C statement called on Washington to remove Patriot missiles, due to go operational on Monday as part of a NATO defense system, from Turkish soil.

The missiles are being deployed alongside systems from Germany and the Netherlands to guard Turkey, a NATO member, against a spillover of the war in neighboring Syria.

"Our action is for the independence of our country, which has become a new slave of America," the statement said.

Turkey has been one of the leading advocates of foreign intervention to end the civil war in Syria and has become one of President Bashar al-Assad's harshest critics, a stance groups such as the DHKP-C view as submission to an imperialist agenda.

"Organizations of the sectarian sort like the DHKP-C have been gaining ground as a result of circumstances surrounding the Syrian civil war," security analyst Nihat Ali Ozcan wrote in a column in Turkey's Daily News.

The Ankara attack was the second 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 Islamist militant attack on the U.S. Consulate in Benghazi, Libya.

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 it fired rockets at the U.S. consulate in Istanbul in 1992, according to the U.S. State Department.

It has been blamed for previous suicide attacks, including one in 2001 that killed two police officers and a tourist in Istanbul's central Taksim Square. It has carried out a series of deadly attacks on police stations in the last six months.

Friday's 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.

Football: Returning Carroll steers West Ham past Swansea

LONDON: On-loan striker Andy Carroll scored only his second goal of the season as West Ham United won 1-0 at home to Swansea City on Saturday to end a run of four Premier League games without victory.

West Ham were largely dominant at Upton Park but could find no way past Swansea's inspired goalkeeper Gerhard Tremmel until Carroll powered home a header from a corner with 13 minutes to play.

Victory lifted West Ham two places to 11th in the table, while League Cup finalists Swansea remain eighth after a first defeat in eight games.

Eager to prevent Swansea from settling into their usual passing rhythm, West Ham snapped into their tackles from the off and Ricardo Vaz Te was booked for a lunge at Wayne Routledge in the eighth minute.

Carroll, on loan from Liverpool, was making his first West Ham start since November 28 and the hosts looked for him at every opportunity as they began to impose themselves on the game.

Tremmel did brilliantly to prevent Kevin Nolan putting West Ham ahead from close range in the 21st minute after Joey O'Brien left Routledge for dead with a step-over on the right flank.

A second contest between Nolan and Tremmel in the 37th minute produced the same result, with the German saving superbly after the home skipper took aim from a Carroll knock-down.

Tremmel came to his side's rescue again shortly before half-time when he diverted a 25-yard shot from Vaz Te around the post.

The hosts remained on the front foot in the second period, with Tremmel repelling Vaz Te again and Carroll hoisting the ball wastefully over the Swansea crossbar from a Matt Jarvis cut-back.

Belatedly, Swansea reacted, Pablo Hernandez testing Jussi Jaaskelainen from a free-kick and top scorer Michu nodding a cross from Hernandez over the top.

Tremmel unleashed yet another fine save to thwart Carroll before the visitors' resistance finally subsided in the 77th minute.

Carroll cleverly shook off the attentions of Ashley Williams inside the Swansea box before planting a header past Tremmel from a corner.

In response, Jaaskelainen saved from Ki Sung-Yueng and then sprang to his feet to block Ben Davies' follow-up effort, while the hosts also survived a desperate scramble inside their own area in the dying stages.

English Premier League results:
Arsenal 1 Stoke 0
Everton 3 Aston Villa 3
Fulham 0 Manchester Utd 1
Newcastle 3 Chelsea 2
QPR 0 Norwich 0
Reading 2 Sunderland 1
West Ham 1 Swansea 0

For Valentine's Day, Cupid ditches arrows, opts for e-cards

Admit it. You've always wanted to love like John Travolta.

(Credit:
Screenshot by Chris Matyszczyk/CNET)

Romance isn't dead.

It's merely been reduced to the level of a friend request, a poke, and a privacy control.

Often in that order.

How else can one interpret the staggeringly predictable research -- performed on behalf of SOASTA, the oddly named company that performs cloud and mobile testing -- that suggests more than a third of American human beings will send an e-card for Valentine's Day?

It's true that some e-cards can be amusing, uplifting, even offering an instant surprise on an otherwise moribund day. But can they truly incite a loving feeling on America's most commercially amorous day of the year?

You will be stunned into loving only yourself for the rest of your days when I tell you that -- of the 2,474 American adults surveyed -- men seem a little keener on Valentine e-cards than women.

Indeed, this research offered that 47 percent of men between the ages of 35 and 44 indicated that the love of their life deserved merely a few clicks and a canned expression of love.

Next in enthusiasm were men aged 18-34, 41 percent of whom will let their fingers do the loving.

But let's not besmirch these men any more than they deserve. 41 percent of women aged 18-34 also claimed that e-cards were their chosen method to stroke their chosen one.

Clearly, convenience is at the heart of this e-card enthusiasm, just as it is at the heart of modern romance.

Respondents were radiant at the idea that e-cards are free. 35 percent beamed at the fact that they offer the possibility of animation. And a deeply serious 34 percent felt the need to point out they were environmentally friendly.

A surprisingly paltry 6 percent admitted that they loved e-cards because you could happily include NSFW content.

More Technically Incorrect

Because ours is an acquisitive society, those who send these free, convenient things to express their temporarily undying love actually expect something in return.

A kiss is expected by 8 percent. A fulsome 10 percent expect sex. They must be among those who believe you can get something for nothing.

There will be those who reach for their Latin and mutter: "Sic transit tragoedia mundi." (Oh, look it up, e-carders.)

But when a whole new personal version of oneself is being created and spun online, who can be surprised that other expressions of love might seem not merely passe but also downright unexpressive?

E-cards surely allow you a far greater breadth than paper cards or balloons to display precisely what you really feel about the most important person in your life.

Which, in the case of 3 percent of the respondents in this moving survey, is "the hot receptionist at work."

Thousands in Egypt defy curfews, protest Morsi

CAIRO Thousands of Egyptians marched across the country, chanting against the rule of the Islamist President Mohammed Morsi, in a fresh wave of protests Friday, even as cracks appeared in the ranks of the opposition after its political leaders met for the first time with the rival Muslim Brotherhood.

The protests continue a week of political rioting that engulfed the country and left up to 60 people dead. The violence prompted Morsi to declare a state of emergency in three restive Suez Canal cities, impose a curfew that thousands of the cities' angry residents defied in night rallies, and left him with eroding popularity in the street.

On Friday, thousands of protesters in the Mediterranean city of Port Said at the northern tip of Suez Canal, which witnessed the worst clashes and biggest number of causalities the past days, pumped their fists in the air while chanting, "Leave, leave, Morsi." They threatened to escalate pressure with civil disobedience and a work stoppage at the vital Suez Canal authority if their demand for punishment of those responsible for protester death is not met.

"The people want the Republic of Port Said," protesters chanted, voicing a wide sentiment among residents that they are fed up of negligence and mistreatment by central government and that they want to virtual independence.

"Your policy is: I don't hear, I don't talk and I don't see," read a flyer distributed by protesters.

Buses carrying protesters from two other Suez Canal cities of Suez and Ismailia carried more protesters to the Port Said rallies.

Last week's violence first erupted on the eve of the second anniversary of 2011 uprising that toppled down longtime authoritarian ruler Hosni Mubarak's regime. It accelerated a day later when security forces fired at protesters killing at least 11 dead, most of them in the city of Suez.

The next day, riots exploded in Port Said after a court convicted and sentenced to death 21 defendants — mostly locals — for a mass soccer riot in the city's main stadium a year ago. Residents saw the verdict as politicized. Over the next few days, around 40 people were killed in the city in unrest that saw security forces firing on a funeral.

Feb. 1 marks the first anniversary of the mass soccer riot in Port Said that left 74 people dead mostly fans of Al-Ahly, Egypt's most popular soccer team.

Egypt's main opposition political grouping, the National Salvation Front, called for Friday's protests in Cairo, demanding Morsi form a national unity government and amend the constitution, moves they say would prevent the Islamist from governing solely in the interest of his Muslim Brotherhood group.

"The policies of the president and the Muslim Brotherhood are pushing the country to the brink, but they are adopting the same language of the old regime and accusing their opposition of betrayal," the opposition said in a statement. "Instead of responding to the street demands, and working with the rest of the national forces that contributed in the revolution to rescue the nation, they are pointing their arrows to media to stifle freedoms," it added

However, the call came a day after the Front held a meeting with Morsi's Muslim Brotherhood under the aegis of Egypt's premier Islamic institution, Al-Azhar, in their first ever meeting. They and other politicians signed a joint statement denouncing violence.

The meeting appeared to have caused rifts within the opposition, with some saying the Front had handed the Brotherhood the high ground by signing a statement that seemed to focus on protester violence and made no mention of police use of excessive force or explicitly talk of political demands.

"Al-Azhar's initiative talks too broadly about violence as if it's the same to kill a person or break a window and makes no difference between defensive violence and aggressive violence, offering a political cover to expand the repression, detention, killing and torture by the hands of police for the authority's benefit," read a joint statement by 70 activists, liberal politicians, actors and writers.

"The initiative didn't represent the core of the problem and didn't offer solutions but came to give more legitimacy to the existing authority," it added.

Those who attended the Thursday's rare meeting between Egypt's rival political camps defended the anti-violence initiative.

Ahmed Maher, co-founder of April 6 group which led the anti-Mubarak uprising, said in a tweet: "I am against violence as a solution." An opposition party leader Ahmed Said said in a statement, "no one can say no to an initiative to stop violence."

Secret Video Shows Bomb Dogs Failing Tests

A new government investigation suggests that the Transportation Security Administration is not collecting enough detailed information to know if its bomb dogs are well trained and capable of finding bombs at the nation's airports, and includes secret video that shows the dogs failing tests to detect explosives.

TSA has been testing bomb dogs in Miami and Oklahoma City and will be testing them at Dulles airport, outside Washington, D.C., this month.

A GAO report released this week, however, says that the passenger-screening canines have not been adequately tested, and included secret video shot over the past year that showed the dogs failing to detect explosives properly at the test airports.

"As part of our review," wrote the GAO, "we visited two airports at which PSC teams have been deployed and observed training exercises in which PSC teams accurately detected explosives odor (i.e., positive response), failed to detect explosives odor (i.e., miss) and falsely detected explosives odor (i.e., non-productive response)."

The report also said that "TSA could have benefited from completing operational assessments of PSCs before deploying them on a nationwide basis to determine whether they are an effective method of screening passengers in the U.S. airport environment."

In a statement, the TSA said it "acknowledges the need to further examine the data collected over a longer term. To that end, the National Canine Program (NCP) will reestablish annual comprehensive assessments. Beginning in March 2013, TSA plans to expand the Canine Website to improve functionality and reporting capabilities addressing a GAO recommendation."

It also said that this month it would complete effectiveness assessments at Miami, Oklahoma City and Dulles airports, and that it would identify the proper places for the dogs to be deployed at 120 airports by the end of fiscal 2013.

The cost of keeping bomb-sniffing dogs on the government's payroll has almost doubled in the past two years, from $52 million to more than $100 million. Each TSA dog team costs the taxpayers $164,000 dollars a year.

"They want to do the right thing," aviation expert Jeff Price told ABC News, "but the homework hasn't been done. A lot of money gets spent before they know something works."

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 organization 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.

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 organization 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 furor 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.

Oil prices rise after upbeat US, China data

NEW YORK: Oil prices finished higher Friday in New York, buoyed by greater optimism about global growth following encouraging indicators from the US and China.

A barrel of West Texas Intermediate, the US benchmark, settled 28 cents higher at US$97.77 on the New York Mercantile Exchange.

Even stronger was the price of European oil benchmark Brent futures, which closed at US$116.76 a barrel on the Intercontinental Exchange, up US$1.21. The close was Brent's highest level since May 2012.

Oil prices got a lift from Friday's monthly US nonfarm labour payroll data.

Although the number of net jobs added in January came in below expectations, markets were heartened by a significant upward revision in the 2012 monthly figures.

The Labor Department reported employers added 157,000 jobs in January and upped its estimate for December jobs growth to 196,000.

After a sweeping annual revision of earlier data, the department also said monthly job growth averaged 181,000 in 2012, well above the prior estimate of 153,000 jobs.

The US jobs report was not the only strong data point released Friday, said Dominick Chirichella, an analyst with the Energy Management Institute. There was also strong manufacturing data in the US and China, the world's two biggest energy consumers.

"Pretty much everything across the board was positive," Chirichella said.

The one exception was Wednesday's report on the US economy for the 2012 fourth quarter, which showed gross domestic product shrank 0.1 per cent, the first contraction since the 2009 recession.

But the oil and equity markets "ignored" the GDP reading, Chirichella added.

"Crude is being lifted with all the other markets, even though the underlying fundamentals do not necessarily justify that," said Matt Smith, an analyst with Schneider Electric. "Demand is relatively flat and supply is at a 20-year high."

Oil prices have also been supported by the fall in the US dollar against the euro. Because oil is traded in US dollars, it becomes cheaper for consumers who use other currencies to purchase the commodity.

Still, prices of US benchmark WTI continued to be weighed down by problems at the Seaway pipeline.

The pipeline has encountered operational problems that have limited the flow of oil from the Cushing, Oklahoma-based trading hub to refineries on the US Gulf Coast, producing a glut of oil at landlocked Cushing that has pressured prices.

Next up for 3D printing: a moonbase?

We've put man on the moon. Perhaps setting up a 3D moonbase will be next.

The European Space Agency (ESA) and architecture and design firm Foster + Partners are jumping on the 3D-printing bandwagon and exploring the feasibility of using three-dimensional printing to create buildings on the moon.

Engineering teams from both parties are investigating the properties of lunar soil, known as regolith, to see if the material could be used to print "bricks" for a moonbase, thus solving the sticky issue of transporting construction materials from our planet. Previous research from Washington State University and NASA has suggested that moon rocks could be used to print useful objects like tools or replacement parts.

Here's how the plan works in theory. A capsule, housing the 3D printer, is sent down to the moon's surface. Once it's landed, an inflatable dome that can house four people springs up as a base, and layers of regolith are built up to cover the inflatable shape -- operated by a robot -- to solidify a protective shell.

Once complete, the moonbase imagined by ESA and Foster + Partners should offer protection from meteorites, gamma radiation, and temperature fluctuations. The planned site for the new building is at the moon's southern pole.

Preliminary tests of this concept are already under way, as researchers have used simulated lunar soil to create a 1.5-ton building block mockup in a vacuum chamber to echo typical lunar conditions. Perhaps in the future this will be a way to afford further explorations of the moon while offering astronauts additional protection.

We have, of course, already seen some unusual uses for 3D printing -- everything from meat and printable robots to 3D replicas of yourself.

Janjaap Ruijssenaars of Amsterdam-based Universe Architecture has created the concept of a 3D-printed house created from slot-in components that can be printed and then reinforced at otherwise-weak joints. In addition, Studio Softkill recently announced a new concept design called Protohome that uses printed, fibrous pieces to construct a "web" rather than a solid mass when building a home.

Once assembled, inflated domes are covered with a layer of 3D-printed lunar regolith by robots to help protect the occupants against space radiation and micrometeoroids.
