Immediately after, the UAV recorded a surface-to-air missile system (9K33 Osa) (in violation of withdrawal lines) about 2km north-west of Panteleimonivka (non-government-controlled, 26km north-east of Donetsk), and about 4km north-east of the area where the UAV was flying, firing a second missile in the direction of the UAV which also followed a ballistic trajectory at a significantly lower altitude than the UAV. About three minutes later, the UAV recorded a probable anti-aircraft gun (ZU-23, 23mm) located near the surface-to-air missile system also firing several rounds in the direction of the UAV. The SMM assessed the fire as directed at the UAV which was returned to base safely.
