Iraqi security forces open fire at a drone above Baghdad's Green Zone

It was not clear if the drone was armed, but one Iraqi military officer said initial assessment suggests the drone was on a surveillance mission. The drone flew away amid the heavy gunfire to down it, said the sources. The Green Zone in the Iraqi capital houses the U.S. embassy, other missions and government offices.
