Russia: Trace of Western-made nerve agent seen in UK samples - The Washington Post
MOSCOW — Russia’s foreign minister says Moscow has received a document from a Swiss lab that analyzed the samples in the nerve agent poisoning of an ex-Russian spy, which points at a Western-designed nerve agent as a likely cause.
He said the analysis was done at the request of the Organization for the Prohibition of Chemical Weapons.
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.
