Defence systems at Iraq's Ain al-Asad air base, which hosts U.S. forces, intercepted and shot down a drone while it was hovering near the base, Iraqi security sources said late on Thursday.
The sources said it was not clear whether the drone was on a surveillance mission or if it was carrying any explosives.
No damages or casualties were reported, the sources added.
Iraqi officials were not immediately available for comment.
