Demonstrators in Egypt and Libya held anti-U.S. protests Tuesday expressing anger about a U.S.-made film they say is offensive to Islam's Prophet Muhammad.

Some 2,000 demonstrators gathered outside the U.S. embassy in Cairo, including Salafist Muslims and feisty soccer fans who were involved in the political protests that brought down the former government. A group of protesters breached the wall, pulled down the U.S. flag and replaced it with an Islamic banner.

An official at the embassy told VOA that no guns were drawn and no shots were fired during the incident. He said all the employees on the compound were safe.

In neighboring Libya, an angry mob gathered outside the U.S. consulate in Benghazi and set fire to the building in protest about the film.

It is not clear if the two incidents were coordinated.

Media reports say the film about the prophet was financed by expatriate members of Egypt's Coptic Christian minority group.

The protests coincide with the 11th anniversary of September 11 terrorist attacks in the United States.
