The U.S. military said two American soldiers were killed and one was wounded by a roadside bomb in Baghdad on Monday, while Iraqi officials reported that at least nine Iraqis died in a series of bombings of Iraqi security forces. The deadliest attack was a roadside bombing against an Iraqi police patrol vehicle in Mahaweel, about 60 kilometers (35 miles) south of Baghdad that killed four policemen and three civilian bystanders, according to Iraqi police. The U.S. military said it could not immediately confirm that attack. The roadside bomb that killed the two American soldiers and wounded another occurred shortly before 10 a.m. in eastern Baghdad, the U.S. military was quoted as saying by the Associated Press.
