Russian Bikers' Trek to Celebrate WWII Soviet Victory Stokes Tension With Poland, Germany

The "Night Wolves" ride to celebrate the Soviet victory is ramping up tensions.

Among the bikers are members of the "Night Wolves," the pro-Putin group that blends black-leather biker culture with messianic Russian nationalism, Orthodox Christianity and Soviet military gear.

Polish border guards said today that they had stopped 10 of the bikers from entering, though Russian media reported that some had managed to cross individually. A number of riders had told ABC News they would try to cross alone.

The roughly two-dozen bikers left Moscow on Saturday, escorted by hundreds of others, many carrying Soviet flags or booming out Red Army songs, as part of the annual opening of the motor-cross season here.

Those taking part told ABC News the ride was purely about historical commemoration and thanking Red Army veterans.
