Russo-Turkish confrontation in Syria

The Turco-Russian confrontation refers to a conflict between Turkey and, initially, the Syrian government which turned into a military crisis between Turkey and Russia after the November 2015 shoot-down of a Russian Air Force Su-24 by the Turkish Air Force after an alleged airspace violation. Increased Russian military aggression and hostile Turkish territorial responses have all contributed to increasing escalation. Aerial confrontations between two nations have grown more common. Turkey accuses Russian Forces of violating Turkish sovereign airspace and war crimes against Syrian Turkmens. The Russian military has accused Turkey of illegal economic ties with ISIS and planning a military intervention in Syria.
