Islamic protesters have pushed barricades and confronted police in front of the U.S. Embassy in Bangkok during a rally against a video produced in the United States that denigrates the Prophet Muhammad.

About 300 police officers were maintaining order Thursday as around 200 men and boys rallied. The protest was organized by a group called the Muslim Group for Peace. It was the second time in less than two weeks that Muslims had gathered at the embassy to rally against the film, which has sparked demonstrations in many Muslim countries.

Protesters said they want the U.S. government to punish the filmmaker.

They called for the U.S. ambassador to Thailand to receive a letter from them and pushed the barricades and policemen after the embassy rejected the demand. They later retreated.
