As it was reported, the BZ substance was found in the reference samples prepared by the laboratory in accordance with the existing systems of investigation quality control. The samples do not have anything in common with the samples taken in Salisbury.
“We should not doubt the credibility of the OPCW laboratories. The laboratories managed to define the active substance applying proved procedures. No other chemical substance found,” the message says.
As it was reported, Sergey Lavrov, Russian Foreign Minister, on April 14 suggested that BZ substance was used in Salisbury, referring to Swiss Center of radiologic and chemical-biological testing in Spiez. Later, the representatives of the center denied the claim.
Britain informs that Sergei Skripal and his daughter were poisoned by Novichok nerve agent, which was developed in the former Soviet Union and produced in Russia.
