You make a claim, you prove it. Can't get simpler than that.
But anyways, thanks for the citations and for proving yourself wrong.
Firstly, I will ignore the bellingcat link because that is a news agency.
Now, onto the link provided that of OPCW, since you didn't bother to read the very article you linked, let me ease the pain of opening a link for you. The report states, " The results show that no organophosphorous nerve agents or their degradation products were detected in the environmental samples or in the plasma samples taken from alleged casualties.", and also that, "The Fact-Finding Mission also issued a report on 2 July 2018 addressing allegations of chemical weapons use in Al-Hamadaniya, Syria on 30 October 2016, and Karm al-Tarrab, Syria on 13 November 2016. On the basis of the information received and analysed, the prevailing narrative of the interviews, and the results of the laboratory analyses, the FFM cannot confidently determine whether or not a specific chemical was used as a weapon in the incidents that took place in the neighbourhood of Al-Hamadaniyah and in the area of Karm al-Tarrab."
