Cooperation between Russian and Ukrainian intelligence services is impossible in the current conditions, Sergei Naryshkin, chief of the Russian Foreign Intelligence Service, said on Sunday.

"After the state coup in that country, under the current authorities, such cooperation is impossible," he said in an interview with the Deistvuyushchiye Litsa (Political Actors) with Nailya Asker-zade on the Rossiya-1 television channel.

The two countries’ intelligence services used to maintain cooperation relations before 2014, he noted.
