Thousands of protesters have gathered outside the American embassy in the Egyptian capital Cairo to express their anger at a film produced in the US which they say humiliates the prophet Mohamed. Some of the protesters entered the embassy compound and tore down the American flag. From Cairo, here is Jon Leyne.
The protesters outside the American embassy in Cairo included hard line Islamists known as Salafists and also members of a football supporters' club known as Ostras. They were angry about the film they say is anti-Islamic which they complained is about to be shown in the United States. Early in the protest, the small group managed to get inside the embassy compound. They pulled down the Stars and Stripes which is flying at the half mast for the anniversary of the September 11 attacks and replaced it with an Islamic banner. A handful of protester continued sitting on the wall, but the embassy compound was surrounded by Egyptian riot police and there was no sign of any confrontation.
Some news just in. Militias in Libya have stormed the American consulate in Benghazi, the country's second largest city. Reports say they were also protesting against an American film which allegedly humiliated the prophet Mohamed.
