BAGHDAD (AP) -- The U.S. military says two American troops have been killed after coming under small-arms fire while distributing humanitarian aid in northern Iraq.
A senior U.S. military official in Iraq says preliminary reports indicate that the shooter was wearing an Iraqi army uniform and opened fire from a distance.
He says the attack took place as the servicemen were passing out blankets Tuesday afternoon near Baaj, west of the volatile city of Mosul.
The official spoke on condition of anonymity because he wasn't authorized to release the information.
He says it's not clear if the attacker was an Iraqi soldier or an insurgent in disguise and that an investigation is under way.
