Turkish authorities have arrested a man suspected of killing a Russian pilot after his plane was shot down by a Turkish jet near the Syrian-Turkish border last November.
The man, identified as Alparslan Çelik, a fighter from a Turkish-backed Turkmen brigade in Syria, was detained on Friday in a restaurant in the Aegean coastal city of İzmir in a group of 14 people, all of whom were also detained. Çelik was arrested by a penal court of peace on Sunday.
Russian defense officials said at the time that the pilot had managed to eject from his stricken plane only to be killed by ground fire from militants inside Syria. His navigator survived but a Russian marine was killed during the rescue mission.
The incident wrecked relations between Russia and NATO member Turkey. Moscow responded with fury, calling the episode a pre-planned provocation and imposing a raft of economic sanctions in retaliation.
Turkey says it shot down the Russian jet in its air space after it ignored repeated warnings. Russia says it was flying over Syria and was struck unprovoked.
