Islamic State (Isis) extremists have executed another young Iraqi man by throwing him from the top of a building after he was accused of being gay, say reports. The brutal execution is said to have taken place in the Isis (Daesh) stronghold of Kirkuk, 146 miles north of Baghdad.

The bloodthirsty terrorists have murdered dozens of allegedly gay young men by pushing them off buildings in their self-declared caliphate in Iraq and Syria. IS believe that homosexuality is incompatible with Islam and the punishment for committing homosexual acts is death.

The latest reported killing of a gay man comes in the month after IS-inspired gunman Omar Mateen killed 49 people at a gay nightclub in Orlando, Florida on 12 June. Mateen was shot dead by police at the Pulse nightclub and speculation after his death suggests that he may himself had been gay.

According to a report published by the ARA News network, but not independently verified by IBTimes UK, activists viewed IS footage of the man being thrown to his death. They added that onlookers then stoned the man's body as it lay on the floor after the fall.

The IBTimes UK has decided not to show the extremely graphic images of the man being executed.

"He was thrown off a roof in front of dozens of people," the report read. "Then Isis militants called on the people to stone the victim, although he was already dead. They started to barbarically stone his corpse."

The brutal punishments are often meted out by judges inflicting their own brand of Sharia law. A photo report published on IS channels says that the feared al-Hisbah religious police conducted the execution after the man practiced "liwat" or homosexual sex.

"Civilians who live under Isis suppression are forced to follow any order by the group, otherwise they could get killed," head of Nineveh media centre Raafat al-Zarari told ARA News. "People sometimes have no choice but showing loyalty to IS."

As well as the brutal killing the photo report also features the police burning cigarettes, which are illegal in the caliphate, and inspecting clothes of civilians living under their command.
