Egyptian demonstrators climbed the walls of the U.S. Embassy in Cairo today and pulled down the American flag to protest a film they say is insulting to the prophet Mohammad.
Update at 2:07 p.m. ET: CNN reports that U.S. security guards fired a volley of warning shots as the crowd gathered outside the embassy walls.
CNN adds that the embassy had been expecting a demonstration and cleared all diplomatic personnel earlier from the facility.
Reuters reports that protesters tried to raise a black flag carrying the slogan: "There is no god but Allah and Mohammad is his messenger."
The news agency says about 2,000 protesters have gathered outside the embassy and about 20 have scaled the walls.
