Russian military intervention in the Syrian civil war

Turkish F-16 fighter jets shoot down a Russian Sukhoi Su-24 aircraft that had allegedly infringed its airspace near the Syrian border. Russia's Ministry of Defence denies the Su-24 entered Turkish airspace and initially said it was shot down by ground fire over Syria's Latakia Governorate. A video emerged of one pilot killed as local rebel Turkmen fighters shot at him while he was parachuting and a video of his body, while the fate of the other pilot is unknown but is presumed dead. A combat search and rescue mission by Russian forces failed to reach them. It is the first time a NATO member has shot down a Russian plane since the 1950s.
