Protesters Storm US Embassy in Cairo

Upset about a movie they believe insults the Prophet Mohammad

Angry protesters climbed the walls of the U.S. Embassy in Cairo on Tuesday and hauled down the American flag, replacing it with a black standard with Islamic emblems, apparently in protest of the production of a film thought to insult the Prophet Mohammed.

The incident prompted a volley of warning shots to be fired as a large crowd gathered outside, said CNN producer Mohammed Fahmy, who was on the scene.

The replacement flag read, "There is no God but Allah and Mohammad is his messenger."
