“Thirty four employees of French diplomatic missions in Russia have been declared persona non grata,” Russia’s foreign ministry said in a statement, adding that they have two weeks to leave the country.

Moscow made the announcement after summoning France’s ambassador to Russia, Pierre Levy, and telling him that the expulsion of 41 employees of Russian diplomatic missions was a “provocative and unfounded decision”, the statement said.

“It has been stressed that this step causes serious damage to Russian-French relations and constructive bilateral cooperation,” the foreign ministry said.

France “strongly condemns” the expulsion of 34 of its diplomats by Russia, the foreign ministry in Paris said for its part.

Saying the step had “no legitimate basis”, the ministry said in a statement that “the work of the diplomats and staff at (France’s) embassy in Russia… takes place fully within the framework of the Vienna Convention on diplomatic and consular relations”.

On the other hand, Paris expelled the Russian staff in April on suspicion of being spies.
