The Syrian Observatory for Human Rights, a UK-based group that monitors the country's war through a network of sources, reported that there were divisions within Jaysh al-Islam, with many fighters unwilling to leave Douma.
The Russian Defense Ministry and Syrian rebel fighters struck a deal on Sunday for the Jaish al Islam, the biggest fighting group in the Damascus suburbs of eastern Ghouta, to leave the area for the opposition-controlled north.
A total of 2,963 militants and their families have evacuated Douma in three batches over the past few days under a deal concluded between the Islam Army and the Syrian government forces under Russia's mediation.
It is also unclear whether all of the Army of Islam fighters have agreed to leave and how long the evacuations will take. Syrian government forces responded by putting the town and other suburbs around Damascus under siege, bombing hospitals and residential areas, and blocking the entry of food and medical relief.More news: Cristiano Ronaldo sends message to Juventus fans who applauded his bicycle kick
