Images have emerged of a heavily-built executioner ramming a knife through the chest of a man deemed to have committed â€œcrimes against the caliphateâ€.
The victim, named by news agency ABNA as Abdulhadi Essa al-Salem, was stabbed in the heart before being shot in the head in the ISIS stronghold of Raqqa, Syria.
Shocking photos, posted on Twitter by Syrian activist group Raqqa is Being Slaughtered Silently, show the victim then being crucified in public.
According to ABNA, he had been accused of co-operating with the US-led coalition against the heinous jihadi cult.
It is the latest gruesome method of execution carried out by ISIS extremists, who infamously set Jordanian pilot Moath al-Kasasbeh on fire before dumping rubble on his burning corpse.
Yesterday, The Express reported that ISIS â€“ also known as Daesh â€“ had thrown a man from a building feet first for allegedly being a homosexual.
The unidentified victim had been accused of â€œsodomyâ€, according to local sources, and was punished for his supposed crime by being pushed off the five-storey structure in Aleppo.
