During the last 48 hours, the Syrian Arab Air Force (SyAAF) stepped up its bombing camping on ISIS positions in al-Hajar al-Aswad and the Yarmouk camp, which boosted the SAA advance there.
From its side, the ISIS-linked news agency Amaq claimed that ISIS fighters had killed 22 soldiers of the SAA during clashes in the Yarmouk camp and the districts of al-Hajar al-Aswad and al-Tadamon on May 12.
Earlier this week, Syrian opposition sources revealed that the besieged fighters of ISIS in southern Damascus are facing catastrophic circumstances. According to the sources, most of the terrorist group ammunition and fuel depots were destroyed and remaining fighters are suffering from shortage in food, water and medical supplies.
Local observers believe that these conditions will lead to the collapse of the ISIS defense in southern Damascus very soon.
