U.S.: hunt down perpetrators of Benghazi attack

The United States on Wednesday vowed to avenge the killings of its ambassador to Libya & other Americans, moving warships toward the Libyan coast & preparing to track the suspected perpetrators with surveillance drones, officials said.

The slain ambassador, Chris Stevens, helped save Libya's eastern city of Benghazi in the work of last year's revolution. They died there Tuesday night, along with another diplomat & State Department security officers, when a mob stormed the U.S. Consulate & set it ablaze.

The Benghazi consulate was of several American diplomatic missions that faced protests after the world wide web release of a film that ridiculed Muslims and depicted the Prophet Mohammed as a kid molester, womanizer and ruthless killer.
