A car bomb exploded near a U.S. patrol Tuesday near the northern town of Beiji, killing four Iraqi civilians and injuring 19 people, two of them American soldiers, the U.S. military said. Another soldier from the 1st Infantry Division was wounded when insurgents fired a rocket-propelled grenade at an American tank south of Beiji, 250 kilometers (155 miles) north of Baghdad. The two attacks occurred about 9:10 a.m., the military said.
