Today, on the anniversary of the attack on Duma, we are releasing our new interactive web portal, making available our dataset of 345 chemical weapons attacks over the course of the Syrian war. We hope this will give a sense of the scale of the challenge. https://chemicalweapons.gppi.net 

We will be releasing more web essays, reports and briefings in the weeks and months to come. In the meantime, you can always re-read our study from last year, detailing the strategic and operational logic of the Syrian regime's chemical weapons campaign. https://chemicalweapons.gppi.net/
