GALLERY: Violent anti-American protests enter their fourth consecutive day, spreading further through the Middle East and into other continents. Islamists here are seen at American embassies in Egypt, Tunisia, Iran, Iraq, Pakistan, Bangladesh, Sudan, Great Britain, and Kenya, among other countries.

Since Tuesday's 9/11 anniversary, American diplomatic offices in the Middle East have been under siege from Islamists angered by a YouTube clip allegedly criticizing Mohammed. In Benghazi, protesters raped and murdered America's ambassador to Libya, then killed three of his employees, then burned down the consulate entirely. In Cairo, Egyptian protesters destroyed the American flag and raised Al Qaeda's flag over the city's U.S. embassy. These attacks have spread to countries such as Tunisia, Morocco, and Yemen, where protesters are destroying American flags and buildings in the name of Islam.
