The U.S. military said nine of its soldiers were wounded in a roadside bomb attack in eastern Baghdad on Thursday, Xinhua reported.
"A coalition forces patrol was struck by two improvised explosive devices this morning in the eastern Baghdad district of Rusafa," the military said in a statement.
"Approximately nine coalition forces personnel were wounded in the attack and one vehicle was damaged," the statement said.
Meanwhile, a police source told Xinhua that two roadside bombs struck U.S. patrols near the Shaab Stadium in eastern Baghdad earlier in the day, destroying a U.S. Humvee.
The source could not tell whether the U.S. soldiers sustained any casualty as the troops sealed off the area.
The attack came just a few days before U.S. combat troops are due to withdraw from Iraqi towns and cities, raising fear for a rebound of terror attacks at a time when Iraqi security forces finally struggle to stand on its own.
