Islamists Storm US Embassy CAIRO | (Reuters) - Egyptian protesters scaled the walls of the U.S. embassy on Tuesday, tore down the American flag and burned it during a protest over what they said was a film being produced in the United States that insulted Prophet Mohammad. In place of the U.S. flag, the protesters tried to raise a black flag with the words "There is no God but God, and Mohammad is his messenger", a Reuters witness said. Once the U.S. flag was hauled down, some protesters tore it up and showed off pieces to television cameras. Others burned the remains outside the fortress-like embassy building in central Cairo. But some protesters objected to the flag burning. Many Muslims consider any depiction of the Prophet to be offensive."This movie must be banned immediately and an apology should be made," said 19-year-old Ismail Mahmoud, a member of the so-called "ultras" soccer supporters who played a big role in the uprising that brought down Hosni Mubarak last year. He called on President Mohamed Mursi, Egypt's first civilian president and an Islamist, to take action, without giving details of the film that angered him or other protesters.
