Thank you for posting this. This has received very little coverage by the MSM. I have also mentioned it in a parallel discussion forum on ME updates in this blog.
Caitlin Johnstone also writes about this and also includes a sound recording made by the BBC world service of an interview with a journalist Jonathan Steele.
These whistleblower statements and the increasingly obvious politicisation and therefore lack of reliability and impartiality of the OPCW should be more widely circulated.
