Syrians walk amid the rubble of destroyed buildings following reported air strikes by regime forces in the rebel-held area of Douma, east of the capital Damascus, on August 30, 2015.
In the wake of the purported attack, an Engineering Assessment of two chlorine cylinders observed at the scene, a document which was allegedly excluded from the final report, was conducted in order to evaluate the possible means by which they could have been delivered at the locations.
While the final report said that engineering experts had been asked to assess the trajectory of each of the two cylinders, the newly-unveiled findings lay out competing hypotheses to determine whether the holes in the roof and the positions of the cylinders could be "accounted for by anything other than cylinders being dropped from the sky".
