Iraq Anniversary Photo Gallery FILE - This image made from a video from a U.S. Army Apache helicopter gun sight, posted at Wikileaks.org and confirmed as authentic by a senior U.S. military official, shows two men in the streets of the New Baghdad district of eastern Baghdad after being fired upon by the helicopter on July 12, 2007. Among those killed in the attack was Reuters photographer Namir Noor-Eldeen, 22, and his driver Saeed Chmagh, 40. Two children also were wounded. According to U.S. officials, two helicopters arrived at the scene to find a group of men approaching the fight with what look to be AK-47s slung over their shoulders and at least one rocket-propelled grenade. A military investigation later concluded that what was thought to be an RPG was a telephoto lens and the AK-47 was a camera. (AP Photo/Wikileaks.org, File)
