MOSCOW – The Russian Foreign Minister says that Moscow received a document from a Swiss laboratory that analyzed the samples in the poisoning by neurotoxic agents of an ex-Russian spy, which points to a nervous agent of western design as a possible cause.  Minister Sergey Lavrov said on Saturday that Moscow received confidential information from the laboratory in Spiez, Switzerland, which analyzed samples from the March 4 poisoning site of Sergei Skripal and his daughter in the English city of Salisbury.
He said: the analysis was carried out at the request of the Organization for the Prohibition of Chemical Weapons.
The OPCW report confirmed the British findings that the Skripals were poisoned with a military-grade nerve agent, but did not say who was responsible.
Britain accused Russia of poisoning them with a Soviet design agent, an allegation that Moscow denies.
Lavrov said that the document indicated that the Salisbury samples contained the age of the nerve BZ nt and its precursor. He said that BZ was part of the chemical arsenals of the United States, Great Britain and other NATO countries, while the Soviet Union and Russia never developed the agent.
Lavrov added that the Swiss laboratory also noted the presence of nerve agent A234 in the samples, but added that the laboratory noted that its presence in the samples seemed strange, given the high volatility of the substance and the relatively long period between poisoning and taking samples.
He noted that the OPCW report contained no mention of BZ, adding that Russia will request an explanation from the chemical weapons supervisor.
Britain said Agent A234 belonged to the family of soviet design nerve agents nicknamed Novichok.
Yulia Skripal, 33, was released from the hospital this week. His father remains hospitalized but British health officials say he is improving.
