The aircraft entered Athens FIR (but not Greek airspace) and is making a patrol mission south of Crete.
In these minutes (11:40) the mission is still in progress.
South west of Crete the Turkish P-72A orbited over this Russian Navy Tug (SB742) underway (probably not alone) to Tartus, Syria (Mediterranean base of Russian Navy submarines)
