Homicide Bomber Kills Two

homicide attacker (search) detonated a car bomb Sunday near a joint U.S.-Iraqi checkpoint, killing three people and wounding seven, including four U.S. soldiers in the northern city of Samarra, the military said.

It was the first significant attack in Samarra (search) since U.S. troops moved back into the city earlier this month, claiming a success over insurgents who had made it a virtual "no-go" zone since May.

The dead in Sunday's attack included an Iraqi soldier, a civilian and the homicide bomber, said Maj. Neal O'Brien of the Army's 1st Infantry Division.

Four Americans and three Iraqi soldiers were also wounded in the explosion and evacuated to a nearby military hospital for treatment, O'Brien said.
