Source confirms video of Baghdad firefight

? A gritty war video circulating on the Internet that shows U.S. troops firing repeatedly on a group of men — some of whom were unarmed — walking down a Baghdad street is authentic, a senior U.S. military official confirmed Monday.

The official said the video posted at Wikileaks.org was of a July 12, 2007, firefight involving Army helicopters in the New Baghdad District of eastern Baghdad.

Among those believed to have been killed in that attack was Reuters photographer Namir Noor-Eldeen, 22, and his driver Saeed Chmagh, 40. Two children also were wounded.

The official, who spoke on condition of anonymity because he was not authorized to speak publicly about the video, said the military could not confirm the identities of the Reuters employees in the film.
