Family photographs are seen stuck to a door of an armoured vehicle as a US marine from the 3/5 Lima company aims his rifle during operations in the restive city of Fallujah, 13 November 2004, 50 kms west of Baghdad. US troops tightened their grip on Fallujah but clashed with rebels in Iraq’s third city of Mosul and outside Baghdad where insurgents shot down a Black Hawk helicopter injuring three crew members.
