NATO says one of its unmanned drones has disappeared over Libya, denying reports that an attack helicopter has gone down.
Libyan state television broadcast images of what appeared to be aircraft wreckage on Tuesday.
It quoted an unnamed Libyan military official saying a NATO Apache attack helicopter was downed in Zlitan, about 85 miles (135 kilometers) east of the capital Tripoli.
A NATO spokesman says the alliance lost radar contact with an unmanned helicopter drone Tuesday morning and is looking into the incident. But the spokesman, wing commander Mike Bracken, says NATO has not lost any attack helicopters during its Libya mission.
He says the drone helicopter was performing intelligence, surveillance and reconnaissance over Libya.
