The US Department of State compared Russia's attempts to deny involvement in the poisoning of former spy Sergei Skripal and his daughter with the non-recognition of the occupation of the Ukrainian Crimea and the excesses of Russians in the Donbas, the US State Department spokesperson Heather Nauert wrote on her Twitter page on March 21.

"The United States and the United Kingdom were right not to send our Ambassadors to Russian MFA briefing to hear wild accusations and implausible denials. Russia was responsible for the nerve agent attack. Attempts to deny responsibility follow a familiar script: Crimea, MH17, Donbas, Litvinenko, doping, etc...,” she noted.

Reportedly, on March 20, Russian diplomats flew from London to Moscow, leaving Britain in accordance with the decision of the British government in connection with the poisoning of Sergei Skripal.

As a sign of solidarity with Britain, Poland can also expel Russian diplomats from the country. On March 18, Polish Prime Minister Mateusz Morawiecki discussed this issue with British Prime Minister Theresa May. The same issue was a main focus during the visit of German Chancellor Angela Merkel to Warsaw on March 19.

Earlier, Britain stated that it was suspending all contacts with Russia because of the Kremlin's possible involvement in the poisoning of Skripal.

Reference, on March 5, Skripal, convicted in Russia for espionage in favor of London, and his daughter were hospitalized in critical condition after being poisoned in one of the restaurants in the shopping center in the British city of Salisbury.
