Islamic State fighters have largely withdrawn from a Palestinian refugee camp on the outskirts of Damascus after expelling their main rival, several residents and a Palestinian official said on Wednesday.
The pull-out from Yarmouk leaves al Qaeda-linked Nusra as the main group inside the camp.
The sources said hundreds of fighters of the hardline Islamic State had returned to their stronghold in neighboring Hajar al Aswad, from where they had launched their attack earlier this month.
"Most of them have withdrawn in mostly to-and-fro skirmishes that took place between them and their adversaries," resident Abu Ahmad Hawari said.
Alongside seeking to capture the camp, they sought to defeat their rival, the Hamas-linked Aknaf al Maqdis, an opposition group that was ideologically opposed to them.
Islamic State's arrival in Yarmouk had given the jihadist group a significant foothold a few kilometers from Syrian President Bashar al-Assad's seat of power.
