OPCW chief rejects Russia claim of 2nd Salisbury nerve agent

The head of the global chemical watchdog agency has rejected Russian claims that traces of a second nerve agent were discovered in the English city where former Russian spy Sergei Skripal and his daughter were poisoned.

Britain blames Russia for the attack, which it says was carried out by smearing a Soviet-developed nerve agent known as Novichok on a door handle at Sergei Skripal's house in Salisbury. Moscow denies involvement.

Russian Foreign Minister Sergey Lavrov said Saturday that Moscow received confidential information from the laboratory in Spiez, Switzerland, that analyzed samples from the site of the March 4 poisoning in Salisbury.

He said the analysis - done at the request of the Organization for the Prohibition of Chemical Weapons - indicated that samples 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.

OPCW Director-General Ahmet Uzumcu told a meeting Wednesday of the organization's Executive Council that a BZ precursor known as 3Q, "was contained in the control sample prepared by the OPCW Lab in accordance with the existing quality control procedures." He added "it has nothing to do with the samples collected by the OPCW team in Salisbury." Britain's representative to the OPCW, Ambassador Peter Wilson, slammed the Russian foreign minister's comments as a breach of the treaty outlawing chemical weapons.

"The thing for me that was particularly alarming about Lavrov's statement is, first of all, the OPCW goes to enormous lengths to make sure that the identity of laboratories is confidential and, second of all, either the Russians are hacking the laboratories or they are making stuff up," he said. "Either way, that is a violation of the confidentiality of the Chemical Weapons Convention."
