A fresh outbreak of infighting between foreign-backed Takfiri militants in Syria has left nearly 90 people dead, most of them from militants’ ranks.
Opposition sources on Friday said the battle took place in Abu Kamal in the oil-rich Deir el-Zour Province, near the border with Iraq.
The clashes pitted al-Qaeda-affiliated group al-Nusra Front against its main rival, the so-called Islamic State of Iraq and the Levant (ISIL).
The fatalities include some 60 militants from al-Nusra Front members.
Early on Thursday, ISIL militants took over parts of Abu Kamal; however, they were pushed back by al-Nusra Front forces.
ISIL militants, who retreated to a nearby area, have reportedly executed seven members of the rival Takfiri group.
Months of clashes between different armed groups have killed thousands of militants in Syria.
In late March, ISIL’s military commander Omar Farough al-Turki, was killed in clashes with al-Nusra militants in the northeastern province of Hasakah.
Last February, the so-called Syrian Observatory for Human Rights said infighting among extremist militants operating in Syria had left around 3,300 casualties since January. Similar clashes claimed over 1,000 lives in January alone.
Syria has been experiencing unrelenting militancy since March 2011. The Western powers and their regional allies — especially Qatar, Saudi Arabia and Turkey — are said to be supporting the militants operating inside Syria.
Reports indicate that more than 150,000 people have so far been killed and millions of others displaced because of the ongoing violence.
