Sergey Lavrov, the Foreign Minister of Russia, says that Russia's bombing campaign will continue until terrorist organisations like ISIL and Jabhat al-Nusra are defeated; the Syrian opposition's High Negotiations Committee has voiced outrage at an ongoing government offensive backed by Russian air power and called for a halt to air strikes against civilians, among other demands.
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.
