One activist said up to 100 fighters from the Nusra Front, another al Qaeda affiliate, and the Ahrar al-Sham brigade were killed. They had been captured by ISIL in the town of Tel Abyad, on the border with Turkey.
"About 70 bodies, most shot in the head, were collected and sent to the Raqqa National hospital," the activist said.
"Many of those executed had been wounded in the fighting. The fact that Nusra Front and Ahrar al-Sham are ideologically similar to the ISIL did not matter," he added.
