Fierce clashes between the Syrian regime and extremists have left 83 combatants dead in the country's north-west, AFP reported Friday (June 7th).
Clashes on the edge of the Idlib region have killed 44 pro-regime fighters and 39 extremists and members of other armed groups since Thursday, the Syrian Observatory for Human Rights said.
Extremists on Thursday launched an attack on regime forces, following a series of regime advances in the area.
The deadly assault, in a northern strip of Hama province, comes amid an escalation in violence in areas held by Tahrir al-Sham.
The Syrian regime and Russia have since late April ramped up deadly airstrikes and rocket fire on the region, and fighters have clashed on its edges.
Thursday's attack by Tahrir al-Sham and allied extremist groups on the village of Jibeen follows a series of regime advances in the region in recent weeks, the Syrian Observatory for Human Rights said.
The extremist alliance seized several strategic hilltops in its counterattack, said Observatory head Rami Abdel Rahman.
Meanwhile, regime airstrikes pounded the neighbouring province of Idlib and nearby areas on Thursday, as battles raged, the Observatory said.
One civilian was killed in the bombardment, according to the monitor.
