The former Soviet scientist, Vil Mirzanyanov, who 'blew the whistle' and wrote about the 'Novichoks', now lives in a $1 million home in the United States. The AFP news agency just interviewed him about the recent incident:
Mirzayanov, speaking at his home in Princeton, New Jersey, said he is convinced Russia carried it out as a way of intimidating opponents of President Vladimir Putin.
"Only the Russians" developed this class of nerve agents, said the chemist. "They kept it and are still keeping it in secrecy."
The only other possibility, he said, would be that someone used the formulas in his book to make such a weapon.
