Russian warships have entered Cuban waters for the first time since the end of the Cold War.
A Russian destroyer and two support ships sailed into Havana Bay on their way home from joint exercises with the Venezuelan navy.
It is the latest sign of improved ties between Moscow and communist-run Cuba, which were allies during Soviet days.
Russia has been angered by US plans for a missile defence system in Europe, and its support for Georgia in the recent conflict with Russia.
The Russian embassy in Cuba told the AFP news agency that the ships were on a friendly, working visit designed to “develop” relations and “co-operation” between the two countries.
But analysts say Moscow is sending a symbolic message to the US about the consequences of Washington’s activity in regions that Russia regards as its sphere of influence.
Cuba’s communist leadership was closely allied to Moscow during the Cold War, but relations have weakened since the fall of the Soviet Union in 1991.
This situation might need to be watched closely….or the possiblity of another missile crisis could be in the making.
