BAGHDAD, Sept 6 (Reuters) - A U.S. air strike on a Baghdad neighbourhood overnight killed 14 people and demolished several houses, the police said on Thursday. U.S. military spokesmen could not immediately be reached for comment. Two police sources said the air strike took place at about 3 a.m. (2300 GMT Wednesday) in the Washash neighbourhood, a stronghold of Shi'ite cleric Moqtada al-Sadr's Mehdi Army militia, in western Baghdad's Mansour district.
