A United States surveillance drone has been intercepted above the Ukranian region of Crimea, a Russian state arms and technology group said today.
"The drone was flying at about 4,000 metres (12,000 feet) and was virtually invisible from the ground. It was possible to break the link with US operators with complex radio-electronic" technology, said Rostec in a statement.
The drone fell "almost intact into the hands of self-defence forces" added Rostec, which said it had manufactured the equipment used to down the aircraft, but did not specify who was operating it.
