Beirut: An elderly Syrian took part in stoning his daughter to death for alleged adultery in a video posted on YouTube by Daesh on Tuesday.

The execution took place in August or September in an Daesh-controlled rural area in the east of the central province of Hamah, according to The Syrian Observatory for Human Rights.

It was the latest in spate of videotaped executions that the militants have posted on social media as they impose their extreme version of Sharia across a swathe of Syria and neighbouring Iraq.

In the video, a bearded gunman in combat fatigues stands behind the father, who is dressed in the white robe and chequered headdress typical of the Syrian countryside.

They both face the young black-clad daughter as the gunman addresses her in the classical Arabic.

“The punishment is the result of crimes which you committed under no duress,” he says.

“You must accept the punishment of God. Do you accept the punishment of God?”

She nods her head in assent, then turns to her father and asks his forgiveness.

He refuses, saying “even if God forgives you, I will not”, until the assembled Daesh fighters persuade him to relent.

But it makes no difference to his daughter’s fate.

She is permitted to speak briefly before the stoning commences.

“I say to every woman: preserve your honour ... and I appeal to every father to pay attention to the surroundings your daughter lives in,” she says.

Her father then takes a rope, and ties it round his daughter’s waist before forcing her to lie down.

The Daesh gunman then orders punishment to begin and the father joins in stoning her to death.

The video drew condemnation from the mainstream Syrian opposition in exile.

“We condemn this horrible crime committed by Daesh against this woman in the Hama countryside,” the National Coalition said in a statement

“This crime has nothing whatever to do with the Syrian revolution.”

Update: The video has since been removed from YouTube for violating the site's terms of service.
