"The Islamic court in Wilayet al-Furat decided that a man who has practised sodomy must be thrown off the highest point in the city, and then stoned to death," read a statement accompanying the images.

Wilayet al-Furat refers to an area stretching across the Syrian-Iraqi frontier, where the Euphrates flows from Syria into Iraq at the Albu Kamal-Qaim border crossing.

One image shows a man whom the terrorists claimed was “gay” being hurled off a building at an unspecified location in Syria or Iraq. The next shows the man lying on the ground.

The ISIS in November stoned two men to death in Syria, claiming they were gay.

In another separate incident the militant group beheaded a man in northern Syria after accusing him of blasphemy, a militant website and a rights group said on Tuesday.

The man was killed in a public square in the town of Sulouk on Monday in front of a crowd that included children, the British-based Observatory for Human Rights said.

Rights groups say ISIS has beheaded and stoned to death many people in areas it controls in Syria and Iraq for actions they see as violating their interpretation of law, such as adultery, stealing and blasphemy. They have also killed a smaller number of foreign captives.

A statement posted on a terrorist’s website said the man admitted to blasphemy before being killed in the countryside of Raqqa province, which the hardline group controls.

The website included images of crowds at the square. One photo showed a blindfolded man kneeling with his head on a wooden block as a masked man in black raised a sword over his neck.

The Observatory, which tracks the conflict using sources on the ground, said last month that ISIS had killed 1,432 Syrians off the battlefield since the end of June when it declared a caliphate in the territory under its control.

The group, which is being targeted by U.S.-led strikes in Iraq and Syria, has often displayed bodies in public after the killings.
