Asked to back up his claims, Yakovenko replied: "I cannot present you the evidence. This is some kind of information that we have." He claimed Moscow was the victim of an "aggressive anti-Russian campaign" by the British government, a "well-orchestrated campaign" to discredit Russia, supported by UK media.
Yakovenko said the Skripal suspects had officially confirmed their identities in a television interview and denied they were working for the GRU.

Asked about claims of GRU international computer hacking attempts, including at the Organisation for the Prohibition of Chemical Weapons in The Hague, he said: "of course I deny".
He said Russia was readying to ask "a lot of questions" at the OPCW in the coming days.
