GAZA STRIP -- Dozens of Palestinians in Gaza Strip on Wednesday burned an American flag in front of the United Nations headquarters to protest a U.S. film mocking the Islamic prophet Muhammad.

About 100 members of the militant group Popular Resistance Committees chanted anti-American slogans and called for the death of the California filmmaker behind the movie.

“We call upon Arab and Islamic countries to expel American ambassadors until Obama administration apologizes to Muslims around the world,” said one protester, who would only identify himself as Abu Mussab.

Leaders of Hamas, which controls Gaza Strip, called for more protest on Friday.
