Usual suspect

Toxin co-developer: Only Russia could be behind British poison attack.

PRINCETON: A Russian chemist who helped develop the Soviet-era nerve agent used to poison a former Russian double agent in southern England said only the Russian government could have carried out the attack with such a deadly and advanced toxin.

Vil Mirzayanov (pic), 83, said he had no doubt that Russian President Vladimir Putin was responsible, given that Russia maintains tight control over its Novichok stockpile and that the agent is too complicated for a non-state actor to have weaponised.

“The Kremlin all the time, like all criminals, denying – it doesn’t mean anything,” Mirzayanov said in an interview in his home in Princeton, New Jersey, where he has lived in exile for more than 20 years.

Sergei Skripal, a former Russian military intelligence agent who betrayed dozens of Russian agents to British intelligence, and his daughter are fighting for their lives after they were found on March 4 collapsed on a bench, having been poisoned with Novichok, according to British authorities.

British Prime Minister Theresa May said on Monday that it was “highly likely” that Putin was behind the attack, a charge Russia denies.

May on Tuesday gave Russia a midnight deadline to explain how the toxin showed up in the southern England cathedral city of Salisbury.

Russian officials have described the British allegations of Kremlin involvement as a “circus show”.

Mirzayanov said he spent years testing and improving Novichok, the name given to a group of chemical weapons that Russia secretly created during the latter stages of the Cold War. The weapon is more than 10 times as powerful as the more commonly known VX, another nerve agent.

The programmes eventually produced tonnes of the agent, the dissident said, which Russia has never acknowledged.

“Novichok was invented and studied and experimented and many tonnes were produced only in Russia. Nobody knew in this world,” Mirzayanov said in an interview on Tuesday.

In the early 1990s, as countries around the world began signing the Chemical Weapons Convention, a multinational arms treaty to prevent the development and use of chemical weapons, Mirzayanov grew angry that Russia was hiding Novichok’s existence.

He was fired and jailed after detailing the new generation of chemical weapons in a news article, though the charges were eventually dismissed under pressure from Western officials.
