A Russian motorbiker is greeted by Polish supporters of Russian motorbikers group "Night Wolves" after he crossed the EU border in Terespol April 27, 2015. Poland will not allow members of a Russian motorcycle club linked to President Vladimir Putin to cross its border and enter the European Union's territory, the Polish Foreign Ministry said on Friday, a decision Moscow said was politically motivated. Some 50 members of the Night Wolves, a group blacklisted by the United States for taking part in Russia's annexation of Crimea, are taking part in a bike ride from Moscow to Berlin, commemorating the end of World War Two.
