'U.S. Government Assessment of the Syrian Government’s Use of Chemical Weapons on August 21, 2013'

The Syrian regime has initiated an effort to rid the Damascus suburbs of opposition forces using the area as a base to stage attacks against regime targets in the capital. The regime has failed to clear dozens of Damascus neighborhoods of opposition elements, including neighborhoods targeted on August 21, despite employing nearly all of its conventional weapons systems. We assess that the regime’s frustration with its inability to secure large portions of Damascus may have contributed to its decision to use chemical weapons on August 21.
We have intelligence that leads us to assess that Syrian chemical weapons personnel – including personnel assessed to be associated with the SSRC – were preparing chemical munitions prior to the attack. In the three days prior to the attack, we collected streams of human, signals and geospatial intelligence that reveal regime activities that we assess were associated with preparations for a chemical weapons attack.
Syrian chemical weapons personnel were operating in the Damascus suburb of ‘Adra from Sunday, August 18 until early in the morning on Wednesday, August 21 near an area that the regime uses to mix chemical weapons, including sarin. On August 21, a Syrian regime element prepared for a chemical weapons attack in the Damascus area, including through the utilization of gas masks. Our intelligence sources in the Damascus area did not detect any indications in the days prior to the attack that opposition affiliates were planning to use chemical weapons.
Multiple streams of intelligence indicate that the regime executed a rocket and artillery attack against the Damascus suburbs in the early hours of August 21. Satellite detections corroborate that attacks from a regime-controlled area struck neighborhoods where the chemical attacks reportedly occurred – including Kafr Batna, Jawbar, ‘Ayn Tarma, Darayya, and Mu’addamiyah. This includes the detection of rocket launches from regime controlled territory early in the morning, approximately 90 minutes before the first report of a chemical attack appeared in social media. The lack of flight activity or missile launches also leads us to conclude that the regime used rockets in the attack.
Local social media reports of a chemical attack in the Damascus suburbs began at 2:30 a.m. local time on August 21. Within the next four hours there were thousands of social media reports on this attack from at least 12 different locations in the Damascus area. Multiple accounts described chemical-filled rockets impacting opposition-controlled areas.
Three hospitals in the Damascus area received approximately 3,600 patients displaying symptoms consistent with nerve agent exposure in less than three hours on the morning of August 21, according to a highly credible international humanitarian organization. The reported symptoms, and the epidemiological pattern of 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 – were consistent with mass exposure to a nerve agent. We also received reports from international and Syrian medical personnel on the ground.
We have identified one hundred videos attributed to the attack, many of which show large numbers of bodies exhibiting physical signs consistent with, but not unique to, nerve agent exposure. The reported symptoms of victims included unconsciousness, foaming from the nose and mouth, constricted pupils, rapid heartbeat, and difficulty breathing. Several of the videos show what appear to be numerous fatalities with no visible injuries, which is consistent with death from chemical weapons, and inconsistent with death from small-arms, high-explosive munitions or blister agents. At least 12 locations are portrayed in the publicly available videos, and a sampling of those videos confirmed that some were shot at the general times and locations described in the footage.
We assess the Syrian opposition does not have the capability to fabricate all of the videos, physical symptoms verified by medical personnel and NGOs, and other information associated with this chemical attack.
