Happy 18th anniversary 🥳 to the 🌎Partnership Against the Spread of Weapons and Materials of Mass Destruction. DYK the Global Partnership has helped to destroy >41K tonnes of chemical weapons?

Finally, the section on Syria is basically the same as 2019 except for mention of confirmed use of chlorine by Syria in Kabana on May 19, 2019. Also mentions developments re: the @OPCW Identification and Investigation Team (IIT) which was stood up in 2019 to conduct attribution.

The Iran and Russia sections of the report are basically identical to the 2019 report. The only new material relates to action by @OPCW to include novichok agents on Schedule 1 of the CWC.

Happy to announce that my assessment of how drones, synthetic biology, 3D printing, the Dark Web, and malware can be misused by terrorist groups has been published by @twq
Read it to find out what seven deadly traits these emerging technologies share.

How did the Comprehensive Test Ban Treaty come about and why’s it important? Read Rebecca Johnson’s classic UNIDIR study ‘Unfinished Business: the Negotiation of the CTBT and the End of Nuclear Testing’ @Acronymist @ctbto

The Costanzi Research Group, horrified, stands with the Black community. #BlackLiveMattters

I am usually a measured person, but today, I am sad, frustrated, and angry. The killings of George Floyd, Breonna Taylor, and Ahmaud Arbery lay bare the deep wounds of racism that have plagued our country for too long.

Welcome to the new #OPCW Executive Council members, and our new EC Chair Ambassador Gómez @EESAenPaisesBaj we are looking forward to working with you!


@blumscientific @gregkoblentz @OPCW @UK_OPCW @CanadaOPCW @NLatOPCW @OPCW_ST Chemical precursor lists cannot be comprehensive. It is always possible to go back a step and work with upstream precursors. That being said, the new Australia Group chemicals are indeed the most obvious direct Novichok precursors and should be subject to strict monitoring.

Last February, the Australia Group chemical weapons precursors list has been amended to include 22 Novichok precursors. This complements the recent addition of Novichok agents to Schedule 1 of the Chemical Weapons Convention (CWC), which will enter into force in June.
