BEIRUT – Activists say Islamic militants have crushed a tribal uprising against their rule in eastern Syria following days of clashes.
The armed revolt by the Shueitat tribe in the eastern province of Deir el-Zour was the first sign of local resistance to the Islamic State group since its fighters swept into the province.
The Britain-based Syrian Observatory for Human Rights and Turkey-based activist Thaer ak-Deiri said Monday that Islamic State group fighters regained control of three villages of the Shueitat tribe.
Fighting between the two sides erupted July 30 and for a time the tribesmen managed to evict the Islamic State group fighters from their villages.
The extremist group has taken over much of northern and eastern Syria as well as western and northern Iraq.
