Article by @PACE_News calling on Russia to launch an investigation into the use of a #Novichok nerve agent against #Navalny & to accept a Technical Assistance Visit from the #OPCW. Interesting to consider desired objectives/outcomes of a TAV 1.5 yrs after the incident.
TAVs are normally requested much earlier, eg immediately after an incident. This being said, TAVs respond to needs of the requesting State Party, and there is no time limit to request one if requested expertise is available.
