Riders from a Russian nationalist motorcycle group on Saturday began their run commemorating the Red Army’s offensive against Nazi Germany, despite Poland’s announcement that it would refuse to let them in the country.
About 20 bikers including members of the Night Wolves group set off from Moscow with the aim of crossing into Poland before eventually reaching Berlin on May 9. Poland, alarmed by the aggressive nationalism of the Night Wolves, on Friday said it wouldn’t allow them entry.
The Night Wolves were part of a larger group of several hundred bikers who rallied to mark the start of motorcycling season despite temperatures of 4 degrees (39 F) and intermittent rain mixed with snow.
