Don't forget the Russian Ambassador to Turkey Andrei Karlov, who was assassinated in Ankara by member of the Turkish police force in 2016.
Both Turkey and Russia play a dangerous game.
Historically there are no groups more hostile to each other than Slavs and Turks.
Been that way for most of the written history resulting it more than a dozen of wars between Turkey and Russia.
Although there was a remarkable rapprochment about the end of Cold War, more so recently.
It is not without inertia though.
