The United States says it is tracking a Russian military cargo ship as it makes its way to Syria carrying weapons, ammunition and a small number of Russian troops.

U.S. intelligence believes the Russians are sending the ship to help fortify its naval base in Syria as the situation in country continues to spiral out of control, Pentagon officials told CNN Friday.

Classified U.S. imagery shows the ship, called the Nikolay Filchenkov, began loading in the port of Sevastapol on the Black Sea on June 7 and is headed for the Syrian port of Tartus, where the Russians have a naval facility. The port is vital for Russian naval access to the entire Middle East.

Under maritime rules, Russia should declare what the ship is carrying when it enters the Mediterranean, U.S. officials said.

This may just be 'reinforcements' for the Russian base - or it could be something more.
