Germany will block some members of an ultra-nationalist Russian motorcycle club from entering the country, government sources said Saturday, a day after Poland also announced an entry ban for the group which is blacklisted by the United States.

Some 50 members of the Night Wolves were due to set off from Moscow on Saturday on a motorcycle ride to Berlin they said was to mark the 70th anniversary of victory by Soviet forces over Nazi Germany.

News of the planned ride drew criticism from countries along the route, particularly in Poland, whose prime minister said the trip was a provocation.

The Night Wolves were blacklisted by the United States for their participation in Russia's annexation of Crimea from Ukraine last year. Its members also strongly back pro-Russian separatists in eastern Ukraine.
