Footage of the beating of Sunnis by Shi'a Iraqi soldiers is available here. Obtained by a British public television station, the footage shows the Sunnis being beaten with fists, kicked, and beaten with the butts of weapons. While the beatings are taking place, American soldiers taunt the Sunnis and cheer on the Shi'a soldiers, then help load the victims into the back of a truck.
The beatings were witnessed by two journalists from the First Cavalry division. According to the British television station, American troops threatened the journalists and held them under armed guard, threatening to seize their footage. A U.S. Army commander reports that he has taken action to suspend the platoon sergeant.
