Nasr Akr, an Al-Qaeda-inspired militant, was assassinated along with his aide in the Eastern town of Darna.
The Shura Council of Darna’s militants announced his killing on Wednesday, blaming it on ISIS Takfiri militants.
The killing sparked heavy fighting, leaving at least nine ISIS terrorists dead, according to witnesses.
The ISIS seized control of Darna last year. The ISIS group began as an Al-Qaeda affiliate, but later fell out with the terrorist network.
