I have no idea who bombed the Turks. The Russian military had the order to avoid or ignore them but Turks are shooting at Russian air assets at the same time and it produces nuisance. All in all Russians are flying CAS for the Syrians on the ground and they might easily illiminate Turks for attack or even US forces.
All this conflict is a Charlie Foxtrot of enormous proportions.
There were rumors of a couple of Mig-23s dashing away from the area with wings folded at Mach 2.3. So maybe they were Syrians who bombed the Turks.

Turkish television stations are airing footage of Syrian “refugees” heading to Greece.
