A disturbing video has emerged purporting to show the moment an ISIS fighter celebrates as he 'wins' the chance to become the next suicide bomber.

In the propaganda clip a young man with a walkie talkie strung around his neck holds out his hands to another bearded jihadi who picks the man's right hand, which is revealed to contain a white stone - apparently the ticket to become the next killer.

The bearded man leaps with joy and hugs members of the group before taking what looks like a backpack from a man holding a rifle.

The man who was holding the stone then kisses him on the head as the 'suicide bomber' smiles with joy as his fate is seemingly decided.

The video then cuts to footage of a makeshift armoured car driving through a village.

Next, a plume of smoke is seen rising from behind some buildings in an attempt to illustrate an attack.

It is not possible to verify if the man actually carried out a suicide bomb attack. 

ISIS are desperately attempting to promote their work as many of the terror group's fighters begin abandoning the sick cause.

On Thursday, cowardly ISIS fighters were caught fleeing Mosul in women's clothing after wives and girlfriends were ordered to evacuate the city.

As the battle to liberate Mosul raged into its fourth day in Iraq, the terror group's commander Abu Bakr al-Baghdadi reportedly told women affiliated with the group's leaders to get themselves out of the firing line.

But it appears terrorists have used it as an opportunity to escape capture, by dressing in dresses.

Meanwhile, militants armed with assault rifles and explosives attacked targets in and around the northern Iraqi city of Kirkuk early on Friday in an assault quickly claimed by the Islamic State group and likely aimed at diverting authorities' attention for the battle to retake IS-held Mosul.

Multiple explosions rocked the city and gun battles were underway, said witnesses in Kirkuk, speaking on condition of anonymity as they were concerned for their safety. Much of the fighting was centered on a government compound in the city.

ISIS said its fighters were behind the attack, which the extremist group said targeted the Iraqi government. The claim was carried by the IS-run Aamaq news agency and could not immediately be verified.

Iraqi and Kurdish forces backed by U.S.-led coalition support launched a multi-pronged assault this week to retake Mosul and surrounding areas from IS.

The operation is the largest undertaken by the Iraqi military since the 2003 U.S.-led invasion.

Iraqi officials said they had advanced as far as the town of Bartella, 15 kilometers (9 miles) from Mosul's outskirts, by Thursday.
