Syrian regime forces and their allies shelled what they said were Islamic State and Jabhat al-Nusra positions on the southern outskirts of Damascus on April 20.

The offensive was launched after the initial failure of negotiations to evacuate Islamic State from areas including al-Hajar al-Aswad, and the Yarmouk camp, which houses a Palestinian population. There were at least 1,500 Syrian and Palestinians families besieged there, according to a Yarmouk Camp community group.

As the bombardment was ongoing, reports emerged of an agreement to withdraw by insurgents in the area. Reuters said “the army’s bombardment continued pending a full surrender deal.”
