(FNA) -- The sources said that Tahrir al-Sham Hay'at (the Levant Liberation Board), in a statement, has accused Jeish al-Islam of carrying out provocative moves to incite young fighters into internal clashes.

The sources added that Tahrir al-Sham threatened to punish Jeish of Islam over its provocative acts in Eastern Ghouta.

Jeish al-Islam said it wanted to dispatch its forces to one of the checkposts of Faylaq al-Rahman at the entrance of the town of Mesraba to back their comrades, but after arrival of their forces in the town of Arbin, Jeish al-Islam launched a surprised attack on Tahrir al-Sham's positions, said the statement.

It added that Jeish al-Islam will receive a crushing response and punishment over their attack on residential units and killing of the captives in Arbin.

According to reports, Jeish al-Islam has gained control over the town of Arbin and the settlement of Hazeh.

Local sources reported earlier today that over 100 militants, including a field commander of Al-Nusra Front (also known as Fatah al-Sham Front or the Levant Liberation Board), have been killed in clashes between rival terrorist groups in Eastern Ghouta.

The sources confirmed that more than 100 terrorists have been killed and many more have been wounded in fierce clashes between Al-Nusra and Faylaq al-Rahman with Jeish al-Islam in the Eastern countryside of Damascus.

They added that notorious commander of Al-Nusra, nom de guerre Abu Qazi, is among the terrorists killed in the clashes.

The infighting in Eastern Ghouta which started two days ago is still underway, the sources said, adding that the warring parties are pounding each others' position by mortar attacks
