"In order to identify the air target and prevent the violation of the state border of the Russian Federation, a Su-30 fighter jet of the air defense forces was taken into the air. The crew of the Russian fighter identified the aerial target as a reconnaissance UAV MQ-9A Reaper of the US Air Force," the NDCC said in a statement.
The drone changed its course after spotting the Russian jet and did not violate the country's airspace, the statement added.
The MQ-9 Reaper is a reconnaissance and attack drone with a wingspan of 20 meters (66 feet), a maximum weight of 4.7 tonnes and an endurance of 27 hours.
