Protests ignited by a controversial film that ridicules Islam's Prophet Muhammad spread throughout Muslim world.

A Libyan government militia guarding the main entrance of the U.S. consulate that was attacked last week, fixes a note written by Libyans against the attack, in Benghazi city on Sept. 18. An amateur video appears to show Libyans trying to rescue U.S. ambassador Christopher Stevens from a room filled with smoke at the U.S. mission where he was found unconscious after last week's attack by a mob protesting against a film that denigrates the Prophet Muhammad. The poster on left reads, "No to extremism, no to terrorism in free Libya".
