[21] According to the pro-opposition activist group the SOHR, ISIL took full control of al-Qadam, with 36 soldiers being killed and dozens of others wounded, captured or missing.

[20] In contrast, military sources initially reported control of al-Qadam was divided[22] and that ISIL failed to capture the central and western neighborhoods of the district.

During the night of 19 May, an agreement was put in place in southern Damascus between the Syrian Army and ISIL after the militants agreed to surrender their last positions in the Yarmouk Camp and Hajar Al-Aswad.
