Moscow will retaliate shortly over the expulsion of Russian diplomats following the poisoning of an ex-spy in Britain, the Russian Foreign Ministry said.
The ministry’s spokeswoman Maria Zakharova said the Russian response will come “in the nearest time”.
Two dozen countries, including the US and many EU nations, have ordered more than 150 Russian diplomats out this week in a show of solidarity with Britain.
Ms Zakharova said the expulsions came after “colossal” pressure from Washington and London, adding that the nations that succumbed to it “made a grave mistake”.
She denounced Britain’s assertion that Russia was behind the nerve agent attack on ex-spy Sergei Skripal and his daughter as a “swindle” and an “international provocation”.
Ms Zakharova insisted that Moscow is demanding access to materials of the investigation.
