A group of Bedouins stormed an international peacekeepers' camp in Egypt's Sinai Friday to protest against a film mocking Islam, sparking clashes that left three people injured, a security official said.

The Bedouin broke through the fence of the Multinational Force and Observers (MFO) compound and set fire to an observation tower.

In the ensuing clashes two Colombians and an Egyptian were injured, the official said, adding that the extent of their injuries was not immediately clear.
