Amman: The al Qaeda-linked Islamist State of Iraq and the Levant executed dozens of rival Islamists over the last two days as the group recaptured most territory it had lost in the northeastern Syrian province of Raqqa.
One of the activists, who spoke from the province on condition of anonymity, said up to 100 fighters from the Nusra Front, another al Qaeda affiliate, and the Ahrar al-Sham brigade, captured by ISIL in the town of Tel Abyad on the border with Turkey, the nearby area of Qantari and the provincial capital city of Raqqa, were shot dead.
There was no independent confirmation of the report.
“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.
ISIL's growth has alarmed Western nations, who are pushing the opposition to attend peace talks in Switzerland in 10 days' time, and has helped President Bashar al-Assad to portray him as the only secular alternative to Islamist extremism.
Fighting between the ISIL and rival Islamists and more moderate rebels have killed hundreds of people over the last 10days and shaken the hardline militant group led by foreign jihadists.
But the ISIL regrouped and recaptured much of its strong holdin Raqqa city on Sunday, activists said, dealing a blow to rival rebel groups backed by Gulf Arab and Western states.
In Raqqa, the only provincial capital under rebel control, activists said ISIL fighters battled remnants of rival Islamist units including the Nusra Front in several neighbourhoods.
To the north, ISIL recaptured the town of Tel Abyad on the border with Turkey over the weekend.
As a result, Turkish authorities closed a border crossing near the town and pulled out the facility's staff, according to the Syrian Revolution Coordinating Union, an opposition monitoring group.
