ISIL crucifies eight opposition fighters
The Syrian Observatory for Human Rights said on Sunday that the incident happened in Deir Hafer in the east of Aleppo Province.
The Britain-based group said the ISIL will keep the crucified bodies in the city’s main square for three days.
Earlier on Saturday, a video footage showed militants shooting three men execution-style outside of the Syrian city of al-Raqqa.
Al-Qaeda militants are later seen throwing the dead bodies into a cleft in the rocks a few miles south of the execution site.
Clashes between the rival militant groups still continue despite an order by senior al-Qaeda leaders to stop the infighting.
Infighting has plagued militant groups fighting the Syrian government, as the army continues to gain more ground.
The army has captured most of the militant-held towns along the mountainous border with Lebanon since its November offensive began.
Syria has been gripped by deadly violence since March 2011. Over 160,000 people have reportedly been killed and millions displaced due to the violence fueled by the Western-backed militants.
The West and its regional allies including Qatar, Saudi Arabia, and Turkey are giving financial and military support to the militants.
Syrian President Bashar al-Assad has recently said the Takfiri war in his country has strongly shifted in favor of government forces as they have made continuous gains in their fight against the terrorists.
