Maxmpower, an Instagram channel dedicated to Russian military aviation, has posted what appears to be footage of a Russian combat jet approaching to within just several hundred yards of a US MQ-9 Reaper drone.
The video is accompanied by the phrase "Peek-a-boo my little one," and the hashtags #Su27, #Su30 and #Su35 It's not clear where and when the footage was shot.
Russia's defence ministry has not commented on the footage.
The Russian military has reported a considerable uptick in US and NATO airborne activity along Russia's western borders in the Black and Baltic seas, as well as around Russian military facilities in Syria, in recent years. In 2018 alone, air defence troops tracked around 3,000 foreign combat aircraft, around a third of them consisting of spy planes and reconnaissance drones. Over the same period, Russian warplanes have been scrambled repeatedly to intercept these aircraft and force them to change course.
