Russia has imposed an entry ban on 89 European politicians and military leaders, a move that has angered Europe and worsened its standoff with the West over Moscow's role in the Ukraine conflict.
The list, compiled by the Russian foreign ministry and handed to a European Union delegation in Moscow last week, includes outspoken critics of Russia as well as military and intelligence officials.
Since Russia annexed Crimea in March 2014, the EU has imposed economic sanctions, visa bans and asset freezes on scores of Russian and Ukrainian citizens and organisations.
A spokeswoman for EU foreign affairs said Russia had denied entry to a number of EU politicians, based on their inclusion on the previously confidential "stop list".
"We consider this measure as totally arbitrary and unjustified," she said.
The Russian Foreign Ministry did not comment
