President Barack Obama vowed on Wednesday to bring to justice the killers of the U.S. ambassador and three other diplomats in Libya as he sought to avoid election-year fallout from an attack that cast a spotlight on his administration's handling of "Arab Spring" unrest.
Standing in the White House Rose Garden, Obama condemned the attack in Benghazi as "outrageous and shocking" but insisted it would not threaten relations with Libya's new elected government, which took power in July after rebel forces backed by NATO air power overthrew Muammar Gaddafi.
The targeting of U.S. diplomats in deadly militant violence sparked by a U.S.-made film seen as insulting the Prophet Mohammad, could raise questions about Obama's policy toward Libya in the post-Gaddafi era as he seeks re-election in November.
Obama, apparently seeking to seize the initiative in the aftermath of the attack, pledged to work with the Libyan government to "see that justice is done for this terrible act."
"And make no mistake: justice will be done," Obama said, with Secretary of State Hillary Clinton at his side. He ordered increased security at U.S. embassies around the world, and a Marine anti-terrorist team was dispatched to boost security for U.S. personnel in Libya.
Ambassador Chris Stevens and three embassy staff were killed late on Tuesday when Islamist gun attacked the Benghazi consulate and a safe house refuge in the eastern city of Benghazi, the cradle of last year's uprising against Gaddafi's 42-year rule. Another assault was mounted on the U.S. embassy in Cairo.
Stevens, a 21-year veteran of the foreign service, was one of the first American officials on the ground in Benghazi during the uprising against Gaddafi last year.
Sean Smith, a foreign service information management officer, was identified as one of the diplomats killed. The names of the two others were withheld while the government notified their families.
LIBYA POLICY, CAMPAIGN IMPACT
Obama had hailed Libya's election in July as a milestone in its post-Gaddafi democratic transition and pledged that the United States would act as a partner even as he cautioned that there would still be difficult challenges ahead.
In the series of Arab Spring uprisings that shook the Middle East last year, Obama opted for a cautious strategy that steered clear of a dominant role for the U.S. military and drew criticism from Republican opponents at home for what was described as "leading from behind."
Before the full death toll and details of the Libya attack were known, Obama's Republican presidential challenger, Mitt Romney criticized the Obama administration's initial response and he repeated the charge on Wednesday.
"It's disgraceful that the Obama administration's first response was not to condemn attacks on our diplomatic missions, but to sympathize with those who waged the attacks," Romney told reporters in Florida.
Pushing back hard, Obama campaign spokesman Ben LaBolt criticized Romney for making a "political attack" at a time when the country was "confronting the tragic death of one of our diplomatic officers in Libya," and Obama then reiterated condemnation of insults to the beliefs of others.
"We reject all efforts to denigrate the religious beliefs of others," he said. "But there is absolutely no justification to this type of senseless violence."
Immediately after his speech, Obama, who was due to leave later in the day on a campaign trip to Nevada, visited the State Department to express solidarity with U.S. diplomats around the world.
The Libya crisis has come at a time when the spotlight was already on the Middle East amid escalating tensions between Obama and Israeli Prime Minister Benjamin Netanyahu over how to deal with Iran's nuclear program.
Clinton said the Benghazi attack was the work of a "small and savage group" and that U.S.-Libyan ties would not suffer.
But she seemed to take note that Americans might resent such an attack on U.S. personnel in a North African country they helped to bring out from under long authoritarian rule.
"I ask myself, how could this happen? How could this happen in a country we helped liberate, in a city we helped save from destruction?" Clinton said. "This question reflects just how complicated and, at times, how confounding the world can be."
