The sick video, obtained by the Washington Examiner, was shared on a private online group chat used by the extremist group, the report says.

It is not clear when the footage was filmed.
In the 30-second video, the militants - who have recaptured most of Afghanistan following the US's exit last month - can be heard chanting "Mujahideen" as they hold up the severed head.
One man can be seen holding two blood-drenched knives and eventually holds them up in the air while another six fanatics carry rifles.
According to the report, it is believed the victim was an Afghan soldier because of his dark green uniform.
The Arabic term Mujahideen means Muslims who fight on behalf of Islam.
In the clip, the men can also be heard praising the Taliban's supreme leader Hibatullah Akhundzada.

The footage ends with the fanatics saying they must shoot the victim's body because "he has to look shot."
This comes as the "lions of Panjshir" resistance fighters have "seized three provinces from the Taliban" fuelling hopes of a crushing fightback.
A news outlet released fresh footage of the brave soldiers conducting military drills and walking through mountain ranges ahead of their bloody battle with the extremists.
Aamaj News reports that Dara, Abshar and Paryan districts have fallen back into the hands of the National Resistance Front (NRF) but that the situation for civilians is "catastrophic".
Panjshir province - which also resisted Soviet occupation 40 years ago - had been regarded as an impenetrable natural fortress.
The Taliban hadn't previously breached the 60-mile valley over the course of the past 26 years.
It comes as a journalist covering the conflict said the resistance had "taken up positions in the mountains and gorges".
Radio Free Europe's Frud Bezhan tweeted: "Fighting is ongoing in Panjshir, last pocket of resistance to Taliban rule in #Afghanistan.
"Taliban control main town and main road in the valley.
"Resistance has taken up positions in the mountains and gorges, and are attacking static Taliban positions."
The "Lions of Panjshir" are in part led by Ahmad Massoud, the son of a legendary freedom fighter known as "The Lion" who defended the valley in the 80s and 90s.
And along with them is Amrullah Saleh, the former vice president of Afghanistan, who declared himself the country's rightful leader as decreed by the constitution.
"There is no doubt we are in a difficult situation. We are under invasion by the Taliban," he said in a video message to the BBC.
He added: "We will not surrender, we are standing for Afghanistan."
