Incident in Salisbury

THE HAGUE, Netherlands — 4 May 2018 — In response to questions from the media, the OPCW Spokesperson stated that the OPCW would not be able to estimate or determine the amount of the nerve agent that was used in Salisbury on 4 March 2018. The quantity should probably be characterised in milligrams. However, the analysis of samples collected by the OPCW Technical Assistance Visit team concluded that the chemical substance found was of high purity, persistent and resistant to weather conditions.

Background

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 Prize for Peace.
