Lavrov said the document indicated that the samples from Salisbury contained BZ nerve agent and its precursor. He said BZ was part of chemical arsenals of the U.S., Britain and other NATO countries, while the Soviet Union and Russia never developed the agent.

Lavrov added that the Swiss lab also pointed at the presence of the nerve agent A234 in the samples, but added that the lab noted that its presence in the samples appeared strange, given the substance’s high volatility and the relatively long period between the poisoning and the sample-taking.

He noted that OPCW’s report didn’t contain any mention of BZ, adding that Russia will ask the chemical weapons watchdog for an explanation.

He said the analysis was done at the request of the Organization for the Prohibition of Chemical Weapons.
