THE HAGUE, Netherlands — 12 April 2018 — The Organisation for the Prohibition of Chemical Weapons (OPCW) transmitted yesterday to the United Kingdom of Great Britain and Northern Ireland (UK) the report of the OPCW’s mission to provide requested technical assistance in regard to the Salisbury incident on 4 March 2018.
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.
The UK’s delegation to the OPCW requested that the Technical Secretariat share the report with all States Parties to the Chemical Weapons Convention (CWC) and to make the Executive Summary of the report publicly available.
The Director-General, Ambassador Ahmet Üzümcü, thanked the four OPCW designated laboratories that supported the technical assistance request for their swift and thorough analysis.
The United Kingdom of Great Britain and Northern Ireland requested technical assistance from the OPCW Technical Secretariat, under subparagraph 38(e) of Article VIII of the Chemical Weapons Convention, in relation to an incident in Salisbury on 4 March 2018 involving a toxic chemical—allegedly a nerve agent—and the poisoning and hospitalisation of three individuals.
The OPCW team worked independently and is not involved in the national investigation by the UK authorities. No State Party was involved in the technical work carried out by the Technical Secretariat.
OPCW designated laboratories are a lynchpin of the Organisation’s verification regime and its capacity to investigate allegations of the use of chemical weapons. They must be able to perform off-site analysis of chemical samples collected by OPCW inspectors from chemical production facilities, storage depots and other installations, or from the site of an alleged use of chemical weapons. These laboratories offer the necessary assurance to our States Parties that chemical analyses needed to make determinations or to clarify issues occurring during OPCW deployments are carried out competently, impartially, and with unambiguous results.
As the implementing body for the Chemical Weapons Convention, the OPCW oversees the global endeavour to permanently and verifiably eliminate chemical weapons. Since the Convention’s entry into force in 1997 – and with its 192 States Parties – it is the most successful disarmament treaty eliminating an entire class of weapons of mass destruction.
Over 96% of all chemical weapon stockpiles declared by possessor States have been destroyed under OPCW verification. For its extensive efforts in eliminating chemical weapons, the OPCW received the 2013 Nobel Peace Prize.
