A convoy of trucks believed to be carrying supplies to a U.S. military base west of Baghdad was ambushed Tuesday, and reporters who arrived after the attack said they saw the bodies of at least seven people. The attack occurred in Habaniyah, 50 miles west of Baghdad and between the restive cities of Fallujah and Ramadi. The victims, all apparently Iraqi men in their 20s and 30s, were placed side by side in a ditch on the side of the road, the reporters said. Several bullet-riddled trucks were on fire and bystanders, including young boys, were seen taking items from the trucks. As some at the scene of the attack tried to put out the fires, a group of heavily armed and masked men came to watch.Hart Security Ltd., a Cyprus-based British security firm, announced that a convoy of trucks its employees were escorting had been "ambushed by insurgents" near Habaniyah.
