Russia said on Wednesday it was barring entry to 21 individuals it accused of working with "the destructive British media" to promote anti-Russian narratives, APA reports citing Reuters.
The list includes journalists, experts and members of NGOs.
Their names were added to those of many hundreds of other Western nationals whom Russia has placed on its "stop list" since the start of the war in Ukraine.
Britain on Wednesday said it was imposing new sanctions on cryptocurrency networks it said were exploited by Russia.
