For the Third Time This Year, Chlorine is Used as a Chemical Weapon in Douma, Damascus

Translations:

As international concerns grow about Syria’s use of chemical weapons, new evidence of the Syrian military’s chemical weapon use continues to emerge from Syria. On the morning of February 1 2018, local activists reported the use of chemical rockets filled with chlorine against opposition held territory in the west of Douma, Damascus:

This represents the 3rd chemical attack reported in Douma since the start of 2018, with two earlier attacks on January 13, and January 22. While munitions are not known to have been recovered from the January 13 attack, munitions used in the January 22 attack were recovered and documented, as were munitions used in the February 1 attack. The design of the munitions recovered in both attacks are identical, and match a design of munition used in a January 30 2017 chlorine attack in Marj al-Sultan, around 8km southeast of Douma.

The rockets are based on modified Iranian 107mm artillery rockets, with the explosive warhead replaced by a large gas cylinder, and additional tail fins added to the rocket. In all three attacks the design of the rockets are identical, and in some cases rockets from the 2018 attacks share the same lot numbers, indicating they are from the same manufacturing batch. This strongly indicates that the rockets used in the 2018 attacks would have originated from the same source:

Using videos posted by Firas Abdullah on the day of the attack it is possible to geolocate the impact sites of three of the rockets used in the February 1 attack to farmlands on the west side of Douma. The warhead of a fourth rocket was photographed but not geolocated. The impact sites are less than 200m west from the only January 22 impact site it was possible to geolocate:

Multiple organisations and individuals have tracked the progress of fighting in the area on a regular basis, showing little movement in the front lines closest to the locations attacked, despite a recent attempt by government forces to capture the area. A map from pro-government “war correspondent, photographer and war map designer” Maxim Mansour posted on January 12 2018, the day before the January 13 chemical attack, shows government forces attacking the area:

Maps from the pro-government South Front website dated January 18 and January 29 show similar front line positions, with no change between the two dates. Maps from the pro-opposition FSA News also show the same front lines during that period, as does the conflict mapping website LiveUAMap. With this agreement among multiple sources about the position of front line positions the closest government positions to the impact sites would be 400-600m away.

It is also possible to establish the likely trajectory of rockets used in the February 1 attack. In one geolocated video, Firas Abdullah films the impact crater of one of the rockets:

The shape of this crater indicates the rocket would have come from the west, from the direction of the Syrian government positions around 1km away. In another video, we see an impact site where the warhead of the chemical munition is still embedded in the ground:

Based on the height of the north-south wall, and how close the warhead is to the wall, it would be extremely unlikely the munition could have come from the east, again indicating the munition would have come from government positions in the west. Further to the west, the 41st Regiment military base can be found 2km away from the impact sites.

SAMS-USA reported that “a SAMS-supported hospital in East Ghouta received 3 patients suffering from suffocation, a dry cough, and vomiting, all of which are consistent w/ the use of chlorine gas. Victims include 2 women & a 16-year-old.”. Ghouta Media Center reported that one civil defence member was injured in the attack. Local reports state the chlorine attack was then followed by a day of heavy shelling in Douma, resulting in the death of two children and multiple injuries.
