The killings in Libya followed protests in Cairo, Egypt, where demonstrators stormed the U.S. embassy compound and tore down the U.S. flag, replacing it with a black flag symbolizing Islam.
U.S. officials believe the attacks were coordinated well in advance to be carried out on the eleventh anniversary of the 9/11 attacks.
U.S. embassies in Armenia, Burundi, Egypt, Kuwait, Sudan, Tunisia and Zambia all issued warnings Wednesday without mentioning specific threats, but saying that demonstrators in those countries could become violent and warned Americans there to be especially cautious.
