Poland's foreign minister says "security regulations" were behind the decision to ban pro-Kremlin Russian bikers from riding through Poland as they mark the anniversary of the end of World War II.

It was Poland's second such ban on the nationalistic Nigh Wolves club since 2015.

In Moscow, Russia's Foreign Ministry said it had summoned Poland's ambassador to protest this "particularly cynical and malicious gesture aimed at deliberate deterioration in Russian-Polish relations. "

Witold Waszczykowski, foreign minister in Poland's right-wing government, said Friday that the bikers were refused entry into Poland due to security concerns. He did not elaborate.

The bikers were planning to pass through Poland on their way from Moscow to Berlin to commemorate the Russian and Allied defeat of Nazi Germany 71 years ago.
