The nerve agent used to poison former Russian spy Sergei Skripal and his daughter in the UK could have been the BZ substance which is used by the US and the UK.
Russia publishes a report by an OPCW laboratory in Spiez, revealing the presence of a substance created in the US, UK and other NATO countries in the sample. The OPCW “could have been provided with a false sample in Skripal poisoning”.
No evidence given. Many competing and contradictory stories promulgated by Russian state-controlled media, the only connecting thread being to confuse their audience and exclude any possibility of Russian involvement https://euvsdisinfo.eu/disinformation-cases/?text=sergei+skripal&disinfo_issue=&date=
The Spiez laboratory has answered and debunked the Russian claims: twitter.com/SpiezLab/status/985243574123057152,
The OPCW have confirmed the UK findings in the case. "The results of the analysis by the OPCW designated laboratories of environmental and biomedical samples collected by the OPCW team confirm the findings of the United Kingdom relating to the identity of the toxic chemical that was used in Salisbury and severely injured three people." www.opcw.org/news/article/opcw-issues-report-on-technical-assistance-requested-by-the-united-kingdom/,
