On 20 April 2008, Georgian officials claimed a Russian MiG-29 shot down a Georgian Hermes 450 unmanned aerial vehicle and provided video footage from the ill-fated drone showing an apparent MiG-29 launching an air-to-air missile at it. Russia denies that the aircraft was theirs and says they did not have any pilots in the air that day. Abkhazia's administration claimed its own forces shot down the drone with an L-39 aircraft "because it was violating Abkhaz airspace and breaching ceasefire agreements." UN investigation concluded that the video was authentic and that the drone was shot down by a Russian MiG-29 or Su-27 using a R-73 heat seeking missile.
