Islamic State's chief executioner has reportedly been stabbed to death during an ambush in Iraq.
Nicknamed Abu Sayyaf, he has beheaded more than 100 people and is among the terror group's most feared decapitators, The New York Evening reported.
He was often also seen in videos posted by the group and was known for collecting the heads of victims, placing them in a hole in the region of al-Khasafa.
Sayyaf was said to be leading Isis in the Nineveh State, on the outskirts of Mosul, when he was killed by an unknown group who attacked the territory.
A source told Alsumaria News: "The armed group ambushed him at al-Dawasa region, in the western side of the city, and stabbed him several times. He died immediately."
However there have also been various reports from some news outlets claiming he was shot by gunmen.
Abu Sayyaf can be translated to mean "father of swordsmith" and an Isis branch in the Philippines holds the same name, it is known for kidnappings and beheadings.
