President Barack Obama on Saturday mourned the week's attacks on a U.S. consulate in Benghazi, Libya which killed four Americans, including the U.S. ambassador to the country.
"These four Americans represented the very best of our country," he said in his weekly address, naming Glen Doherty, Tyrone Woods, Sean Smith, and Ambassador Chris Stevens.
Woods and Doherty were former Navy SEALs, while Smith had served in the Air Force and was a computer expert.
Violence erupted this week in Benghazi and elsewhere in the Arab world - from Morocco to Tehran - based in anger over an inflammatory anti-Islam film. The film was posted online this summer but discussed and aired only recently in portions of the Middle East.
Protesters clashed with police in some cities on Friday, gathering in public squares and outside of embassies.
On Friday, Obama and Secretary of State Hillary Clinton spoke at a Transfer of Remains ceremony near Washington, D.C. when bodies of the four were returned to the U.S. Clinton referred to the "awful internet video that we had nothing to do with" and called the violence "senseless and it is totally unacceptable."
In his weekly address, Obama reiterated his message from previous statements, that "those who attack our people will find no escape from justice.
"We will not waver in their pursuit. And we will never allow anyone to shake the resolve of the United States of America," he said.
The president said he and the country "reject the denigration of any religion, including Islam. Yet there is never any justification for violence."
Obama and Republican presidential nominee Mitt Romney exchanged sharp words regarding the response to the attacks in statements and interviews, with Romney saying the Obama Administration "sympathize(d) with those who waged the attacks" and Obama charging Romney "seems to have a tendency to shoot first and aim later."
