According to the statement made by Serbian military and diplomatic services, the suspicious UAV was about 150 km from the plane of Sergey Shoygu, the Russian Minister of Defence. The device was spotted in Kosovo with the help of ground-based radars. After identifying the device, the Serbian Air Force deployed MiG-29 aircraft in order to eliminate the threat from an unauthorized drone. As a result, the drone did not cross the Serbia-Kosovo border.
