Iranian state television has shown images of what it says is an unmanned US drone captured in its airspace.
The Revolutionary Guards said they had brought down a ScanEagle - one of the smaller, less sophisticated drones employed by the Americans.
Rear Admiral Ali Fadavi told the Fars news agency that the drone had conducted several reconnaissance flights over the Gulf in recent days.
