ISIS militants are using weird sick notes in a desperate bid to escape fighting on the frontline, documents reveal.
Coalition forces found documents that belong to the Tarek ibn Ziad battalion that operates in the war-torn country.
Tarek ibn Ziad is understood to be a terror cell made up of mainly European fighters tasked with carrying out attacks in the Middle East. "He was a reflection of the brutality of this terrorist group", Muhammad Yawar, an Iraqi journalist, said confirming the executioner's death.
The stronghold has been widely regarded as their Iraqi based since they seized power back in 2014, but their position is weakening.
According to a report from Iraq's ARA News station, the executioner died Sunday in an ambush attack in Ninevah.
The hulking man who was pictured with his face masked and wearing black robes from head to toe in ISIS (Islamic State in Iraq and Syria) propaganda photos and videos as he butchered his victims was known as "Abu Sayyaf".
Abu Sayyaf, infamous for his beefy physique and pitch-black clothing that covered him from head to toe, was gunned down Sunday by several shooters who rode up to him in a vehicle near Mosul, ARA News reported.
Abu Sayyaf had beheaded hundreds of people in front of the camera.
Western Mosul is now the new battlefield for Iraqi government forces, who with the help of the US-led coalition force, succeeded in liberating east Mosul a week ago.
The executioner, whose name translates to "father of swordsmith" was known for collecting the heads of his victims and throwing them away in the same hole.
