Which means they found something and are still investigating. It clearly says "Work by the team to establish the significance of these results is on-going. The FFM team will continue its work to draw final conclusions.". Chlorine is used in chemical weapons and that's what they found. Nowhere in the report does it say they found nothing... Previous reports for other sites confirm the use of chemical weapons. So even if they find they didn't use them on this occasion, they still used them in this conflict and Russia still tried to cover it up. Literally no one else is siding with Russia and Syria on this.
