Insurgents attacked a U.S. Army patrol Saturday in Baghdad, killing one American soldier and injuring nine others, the U.S. military said. The unit came under coordinated attack, which included roadside bombs, small arms fire and rocket-propelled grenades, the military said. The statement did not say where the 7 a.m. attack occurred. However, three U.S. Army vehicles were seen on fire after an insurgent attack early Saturday on a police station in the Azamiyah district. One Iraqi policeman was killed.
