Ukraine's state security service, the SBU, banned 23 Russian citizens from entering this country; they are the same diplomats who had been ousted from the United Kingdom because of the high-profile case of Sergei Skripal. This was mentioned in the message of the SBU's press service.
'The SBU banned entrance for those twenty-three Russian citizens, connected to Russian special services and expelled from Great Britain due to the poisoning of Sergei Skripal and his daughter,' the message reads.
SBU head Vasyl Hrytsak added that 'the actions of these people are an insolent mockery over one of the key functions of any diplomatic office, defined by the 1961 Vienna Convention, which is encouraging friendly relations between countries'. According to him, Russian spies have been using diplomats' disguise to resort to cynical provocations, which aim to undermine the basics of international stability and security.
Ex-colonel of Russia’s Main Intelligence Agency, Sergey Skripal and his daughter, poisoned in the center of Salisbury town in the evening of March 4, are still struggling for life in the intensive care unit of the local hospital. The British special services suppose that Skripals was poisoned by his ex-colleague Andrey Lugovoy, who acted on orders from Moscow.
Later, Theresa May, British Prime Minister, stated that Russia was highly likely to be involved in Skripal’s case. Later, Britain had officially confirmed the use of Novichok nerve agent in Salisbury. Due to this, British representative accused Russia of violating of UN Charter and Chemical Weapons Convention at the UN Security Council session.
