On April 14, the Syrian Arab Army and its allies liberated the town of Douma and thus the entire region of Eastern Ghouta, near the Syrian capital of Damacus. Government forces also captured all the infrastructure created by Jaish al-Islam in Douma.

A Syrian photographer, Wassim Essa, has released a big photo report showing Jaish al-Islam's key HQ in Douma.
