Islamic State [Isis] jihadists say they have thrown a gay man off a rooftop and stoned him to death for blasphemy.

The jihadists have also published a photograph to corroborate the punishment handed over to the victim, by what they call as the Islamic court.

"The Islamic court in Wilayet al-Furat [Iraq-Syria frontier] decided that a man who has practiced sodomy must be thrown off the highest point in the city, and then stoned to death," read a statement released by the IS.

While the first picture released by the Sunni extremist group shows the homosexual man being dragged to the top of a building in an unknown location, the second image shows a man lying on the ground.

In a related incident another man in northern Syria was beheaded for blasphemy charges by the Islamists.

The latest grisly episodes have taken place after two gay men were stoned to death by the IS in November. The extremist organisation has sought to establish itself as a caliphate in the captured territories of Syria and Iraq forcing hardline Islamic Shariah principles.
