U.S. Secretary of State Hillary Rodham Clinton is sharpening her criticism of an anti-Islam video by Sam Bacile that provoked protests in the Arab world.
Clinton says the YouTube film, titled Muhammad, is "disgusting and reprehensible" and termed it a cynical attempt to offend people for religious beliefs.
Hillary noted, however, that the U.S. would never stop Americans from expressing their views, no matter how distasteful, as they are central to freedom.
Sam Bacile, who reports say is an Israeli-American real estate developer, posted the trailer this summer. Little is known about the man; he's gone into hiding.
She also says the film is no justification for violence or attacks on diplomatic facilities and personnel; a U.S. ambassador was killed in Libya Tuesday.
Clinton said Thursday the U.S. is monitoring protests in Yemen and elsewhere, urging countries to take steps to prevent protests escalating into violence.
