(Adds details) BAGHDAD, Sept 10 (Reuters) - Seven U.S. soldiers were killed and 11 injured in a vehicle accident in western Baghdad on Monday, the U.S. military said. It said two suspects being transported in the vehicle were also killed. The military said the cause of the accident was under investigation. While U.S. soldiers are periodically killed in nonbattle-related circumstances in Iraq, such a high toll from one accident on the ground is rare. There were no further details.
