The Black Sea Fleet flagship Moskva enters to port of Sukhum

For a better look at the Moskva guided missile cruiser, click on the picture below.

I would note that while the Mosvka's primary mission might be to monitor the movement of NATO vessels in the Black Sea (which be conducted from the Sukhum port mainly by electronic means), the Moskva also provides advanced anti-air capabilities to Abkhazia as it is equipped with long range anti air radars and missiles.
