Over the past months different people and groups have repeatedly asked @OPCW to investigate allegations of the use of Chemical Weapons in different conflicts. You often read "Where is OPCW?".

And the Art IX saga at the @OPCW regarding the #Navalny poisoning enters another round. Note verbale by the Russian Federation from 2 November: opcw.org/sites/default/… A few observations (thread). RU refutes the replies by UK, GER, FR and SWE saying "the responses [...] do not contain the necessary information and [the RU side] perceives them to be formalities with no substance that are propagandistic in nature"
