Philip,
I don't think that Turkey would try to stop any Russian Navy vessels through the Turkish Straits. If they took the option for the likes of Kama then they would have to stop all the others. The Russian Navy "Syrian Express" from the Black Sea has been going on for years now transporting arms and supplies to Syria. After recently patching up relations with Russia I don't believe that they are going to go back down that slippery slope.
See list of Russian Navy vessels through the Bosphorus.

It looks likely that the main task force group is going through the Strait of Gibraltar? Tug Nikolay Chiker sent an international weather message during 18 GMT on HF using Morse Code.
Date/time, Lat/Long, course, speed groups from the message.
