A U.S. Marine lights up a cigarette to a wounded Iraqi who appeared to be a Republican Guard soldier as others Marines search around a bus shot earlier on the key road in Qat'at Sukkar in central Iraq March 27, 2003. Marines treated enemy wounded on Thursday and searched the blood-stained luggage of Iraqis killed inside a bus by a storm of bullets from advancing armoured units. Reporters counted four corpses outside the bus and marines said another 16 lay inside. All the bodies were adult men, wearing a mixture of civilian and military clothing and had papers that appeared to identify them as Iraqi Republican Guard.
