from the second article:
Meanwhile, additional data from Damascus about the actual chemical attack increases the doubts about Washington’s version of events. Immediately after the attack, three hospitals of Doctors Without Borders (MSF: médecins sans frontières) in the greater Damascus area treated more than 3,600 Syrians affected by the chemical attack, and 355 of them died. MSF performed tests on the vast majority of those treated.
MSF director of operations Bart Janssens summed up the findings: “MSF can neither scientifically confirm the cause of these symptoms nor establish who is responsible for the attack. However, the reported symptoms of the patients, in addition to the epidemiological pattern of the events — characterized by the massive influx of patients in a short period of time, the origin of the patients, and the contamination of medical and first aid workers — strongly indicate mass exposure to a neurotoxic agent.” Simply put, even after testing some 3,600 patients, MSF failed to confirm that sarin was the cause of the injuries. According to MSF, the cause could have been nerve agents like sarin, concentrated riot control gas, or even high-concentration pesticides. Moreover, opposition reports that there was distinct stench during the attack suggest that it could have come from the “kitchen sarin” used by jihadist groups (as distinct from the odorless military-type sarin) or improvised agents like pesticides
