Insurgents in Iraq killed or wounded scores of people in several attacks on Saturday, including two American soldiers who were killed by a makeshift bomb on a road near Falluja and three more who died in a truck-bomb attack in Khaldiya, military officials said. On Sunday, a sixth American soldier was killed in the town of Bayji, about 70 miles north of Baghdad, after insurgents attack a military patrol at 10 p.m. on Saturday, said a spokesman for the Fourth Infantry Division, which controls the area.
