Each man is forced to give interview before their murder in which they admit to spying on the terror group's location, movement and armament.

All nine of them - blindfolded with hands bound behind their backs - are then escorted outside by masked terrorists who eventually instruct them to kneel and place handguns to their heads.

They pull the triggers without hesitation, sending their victims jerking forward until their limp bodies hit the dusty ground.

The masked ISIS commander who introduces the latest senseless propaganda video says the men 'were sentenced to death for betraying the religion of Allah'. 

Graphic footage ultimately shows the deceased captives resting perfectly still in a shallow pool of blood.

But the scenes in which the senseless murders take place come six minutes and 30 seconds after the start of the seven minute video.

It begins with a bizarre setup of a masked ISIS commander sitting in a corporate office, flanked by two other soldiers.

He say that Islamic State succeeded in arresting an entire 'cell' of spies who were tasked with monitoring their locations back to their commanding officer.

The unnamed militant then claims three of the men who squealed on the others, adding: 'We took the investigation to a judge and after collecting evidence, they were sentenced to death for betraying the religion of Allah.' 

Each of the nine kidnapped men are then forced to give interviews before their impending doom - presumably under duress - in which they confess to being spies.

Their nationalities and professions are as yet a mystery, but some of the men look visibly terrified as they speak in trembling Arabic. 

This is the second video of an Islamic State execution to surface this week following the equally brutal mass murder of eight 'informers'.
