Insurgents are fighting each other in Syria. Hundred militants have been killed as al-Qaeda-linked groups clashed in the north of the crisis-hit country.

The so-called “Islamic State in Iraq and Levant” terrorists executed dozens of rival Nusra front insurgents in Syria’s northeastern province of Raqqah.

The London-based “Observatory for Human Rights” reported the executions, saying they occurred during the past two days.

Speaking on condition of anonymity, a member of the opposition Observatory said over 100 militants from the Nusra Front and the “Ahrar al-Sham” Brigade were executed during the infighting.

“About 70 bodies, most shot in the head, were collected and sent to the Raqqa National hospital,” a member of the observatory said, adding that, “Many of those executed had been wounded in the fighting.”

This comes as ISIL has managed to seize control of most of Raqqah, which has been its stronghold for months.

Fighting among different foreign-backed insurgent groups spread across northern Syria over the past week.

The so-called Syrian Observatory has said that at least 700 people, including civilians, were killed during nine days of infighting among the foreign-sponsored militants in Syria.
