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.
