Russian special services have been monitoring Sergei and Yulia Skripal for at least five years, as it was stated in the letter of Mark Sedwill, the National Security Adviser, to Jens Stoltenberg, the Nato Secretary General, as Sky News reported.
According to the data, Yulia Skripal’s e-mail accounts were the target of the specialists of Russian intelligence service.
As it was stated in the letter, Russian special services were conducting experiments with the Novichok nerve agent for years, they put the nerve agent on the door-handle, in particular. It is known, that Skripals were poisoned in Salisbury this way.
Besides, the poisoning of Alexander Litvinenko in 2006 was mentioned in the letter as well.
The Organisation for the Prohibition of Chemical Weapons confirmed Britain’s conclusions that ex-GRU officer Sergei Skripal was poisoned with the nerve agent.
Ex-colonel of Russia’s GRU, Chief Intelligence Department, Sergey Skripal and his daughter Yulia, 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 were poisoned by his ex-colleague Andrey Lugovoy, who acted on orders from Moscow.
Earlier, MI6, the British secret intelligence, recommended that former GRU colonel Sergei Skripal and his daughter Yulia change identities and move the U.S. to avoid any new assassination attempts. This was decided after negotiations between MI6 and their counterpart from the CIA.
