UK military research boss says can't say yet whether nerve agent was made in Russia: Sky News

  • "We were able to identify it as Novichok, to identify that it was military-grade nerve agent," Gary Aitkenhead, chief executive of the Defence Science and Technology Laboratory at Porton Down in England, told Sky News.
  • Moscow has denied being behind the attack on Sergei Skripal and his daughter in the southern English city of Salisbury on March 4.

The head of Britain's military research center said on Tuesday it was unable yet to say whether the military-grade nerve agent that poisoned a Russian double-agent last month had been produced in Russia.

"We were able to identify it as Novichok, to identify that it was military-grade nerve agent," Gary Aitkenhead, chief executive of the Defence Science and Technology Laboratory at Porton Down in England, told Sky News.

"We have not identified the precise source, but we have provided the scientific info to government who have then used a number of other sources to piece together the conclusions you have come to."

However, he confirmed the substance required "extremely sophisticated methods to create, something only in the capabilities of a state actor".

He added: "we are continuing to work to help to provide additional information that might help us get closer to [the source] but we haven't yet been able to do that."

Moscow has denied being behind the attack on Sergei Skripal and his daughter in the southern English city of Salisbury on March 4.

After the first known use of a military-grade nerve agent on European soil since World War Two, Britain blamed Russian President Vladimir Putin for the attempted murder, and the West has expelled around 130 Russian diplomats.

Aitkenhead said the British government had "other inputs" it could use to determine the origin of the nerve agent, some of them intelligence-based.

"It is our job to provide the scientific evidence of what this particular nerve agent is - we identified that it is from this particular family and that it is a military grade, but it is not our job to say where it was manufactured," Aitkenhead added.

He reiterated that the substance could not have come from Porton Down. Russia's EU ambassador Vladimir Chizhov noted in an interview with the BBC last month that the British research lab is only eight miles (11 km) from Salisbury, insinuating that may have been the source.

The Foreign Office has said there was "not an ounce of truth" in his implication the nerve agent could have been linked to Porton Down.

Skripal's daughter Yulia is getting better after spending three weeks in critical condition due to the nerve toxin attack at her father's home in Salisbury, the hospital where she is being treated said last Thursday.

Her father remained in a critical but stable condition.
