Heavy Security for Prophet Film Protest in Bangkok More than 700 police will be on guard at the U.S. Embassy in Bangkok as protests against an anti-Islam film produced in the United States spread to Thailand. The U.S. Embassy says it plans to close at midday Tuesday ahead of the protests planned to start shortly afterward. Embassy spokesman Walter Braunohler says Thai police have told the embassy to expect "a large number of demonstrators." He says the embassy is unaware of any threat to Americans but U.S. citizens should exercise caution. Bangkok's police commissioner says security will include hundreds of anti-riot police and plainclothes officers. The Muslim group organizing the protest, the International Al Quds Federation of Thailand, called for a peaceful protest on its Facebook page.
