Two U.S. Navy guided missile destroyers were sent toward the coast of Libya following the killing of the U.S. ambassador to Libya and three consulate employees, Fox News reported citing unnamed military officials.
Ambassador Chris Stevens and three other Americans were killed on Tuesday after the diplomatic facility in Benghazi was attacked by an armed mob angry over a U.S.-produced film that is said to be insulting to Islam’s Prophet Muhammad.
According to Fox News, a team of about 50 U.S. marines was also sent to Libya and will be dispatched in the country’s capital of Tripoli.
