A police official says 15 people were injured in the blast outside a bank in the one-time Sunni insurgent stronghold west of Baghdad. The injured included an Iraqi television cameraman. Police and a crowd gathered in the bank area after an explosion at 6:30 a.m. Wednesday. A second blast caused the casualties. The police official spoke on condition of anonymity because he was not authorized to talk to the media.
