On March 21, an intense fighting continued between the Syrian army and the joint militant forces led by Hayat Tahrir Al-Sham in the Qabun industrial area in eastern Damascus.
As the militants’ attempt to seize this important industrial area and to link up the militant-held Qabun pocket with the militant-held region of Eastern Ghouta entered the third day, the issue of the casualties suffered by the sides became very important.
Thus, according to pro-militant sources between 70 and 90 members of the Syrian army and its allies had been killed and over 100 pro-goovernment fighters had been injured since the start of the clashes. The majority of these casualties were suffered by government forces as a result of attacks of suicide vehicle-borne improvised explosive devices.
The number of killed pro-government fighters is at least partly confirmed by pro-government media activists. The official pro-government narrative denied such a high number of casualties.
In turn, according to pro-government sources, between 90 and 110 members of militant groups (mostly Hayat Tahrir al-Sham) were killed in failed attempts to seize the Qabun industrial area.
While the provided numbers cannot be confirmed independently because the sides hide their casualties on a constant basis, they allow to evaluate the intensity of the ongoing clashes in eastern Damascus and the importance of the area for government forces and their opponents.
