Insurgents in Iraq have ambushed a car in the northern city of Mosul, killing four people.
Witnesses say the attack occurred Friday at an intersection in the western part of the city. Three of the victims appeared to be Westerners, while the fourth apparently was their Iraqi driver. There has been no confirmation of the victims' nationalities.
The victims' bodies were seen lying on the road beside their car. One victim was nearly decapitated. After the attack, the car was set on fire.
The U.S. military believes some insurgents fled to Mosul early last month, before the U.S.-led operation to crush insurgents in the city of Fallujah. Violence in Mosul has increased in recent weeks, and the bodies of dozens of executed Iraqis have turned up in the city.
