The Polish Foreign Ministry says it will not allow a nationalistic motorcycle group loyal to President Vladimir Putin to enter Poland.

The "Night Wolves" group had planned to enter Poland next week to commemorate the 70th anniversary of the end of World War II. Their plan was to cross several countries on their way to Berlin, following a path taken by the Red Army in its defeat of Adolf Hitler's Germany.

The Foreign Ministry in Warsaw said Friday that it gave a diplomatic note to the Russian embassy letting it know of the decision.

Poland's prime minister had called the plans by the bikers a "provocation."

The matter comes at a time of huge strain between the West and Russia.
