U.S. intelligence officials are examining video of a militant group in Niger, looking for clues to the identity of the men who ambushed and killed four U.S. special operations soldiers earlier this month.
The video, which shows a group of young men on motorbikes brandishing rifles and machine guns, was provided to ABC News by Ret. Lt. Col. Rudolph Atallah, a former U.S. military expert on West Africa. He says it came from villagers in the vicinity of the attack.
