WASHINGTON (Reuters) - Two of the four Marines seen in a video appearing to urinate on the bodies of dead Taliban have been identified, a Marine Corps official told Reuters, speaking on condition of anonymity.

The official added that the Marines believed the video was authentic. The two that were identified are still part of the 3rd Battalion, 2nd Marines, based out of Camp Lejeune in North Carolina. That unit served in Afghanistan's Helmand province from March until September of 2011, the official said.
