LONDON — The international watchdog agency that monitors the use of chemical weapons said Thursday that its independent investigators had confirmed Britain’s assertions that the chemical used to poison former Russian double agent Sergei Skripal and his daughter was a military-grade nerve agent known as Novichok.
The Organization for the Prohibition of Chemical Weapons sent a team to Britain from March 21 to March 23 where they took blood samples from Yulia and Sergei Skripal and the Salisbury police officer and first responder Nicholas Bailey.
In a report published Thursday, the organization said they confirmed “the findings of the United Kingdom relating to the identify of the toxic chemical that was used in Salisbury and severely injured three people.”
The inspectors said that the nerve agent was of “high purity” with “the almost complete absence of impurities.”
British officials, speaking on condition of anonymity to discuss the case, said that the high purity of the chemical points toward its creation in a sophisticated laboratory.
Boris Johnson, Britain’s foreign secretary, said in a statement: “There can be no doubt what was used and there remains no alternative explanation about who was responsible — only Russia has the means, motive and record.”
Britain said that Russia — in violation of chemical weapons treaties — has produced the Novichok class of nerve agents in the last 10 years.
The report comes a day after Yulia Skripal, 33, said that she had a “a totally different life than the ordinary one I left just over a month ago.” She was recently discharged from Salisbury district hospital, where her father Sergei remains “seriously ill,” she said.
In a statement issued via the police, she said rejected assistance from the Russian Embassy “at the moment.”
Yulia and her father Sergei, a former Russian double agent, were found March 4 slumped over on a park bench in Salisbury, a quiet city in the southwest of England.
