U.S. embassies in Cairo, Sudan, Tunisia, and Yemen were all under siege Friday as protesters angered by an anti-Muslim film continue to demonstrate. Two people were killed and at least 28 were wounded during protests in Tunisia, according to state television. In Cairo, rioters continued to clash with police outside the embassy, leaving 27 injured. In Sudan, 3 are reported dead after protesters attacked the German Embassy, while others reportedly broke into the U.S. Embassy. A U.S. Marine Corps security team is being sent to Yemen and Sudan to defend U.S. posts, military sources tell CNN.
