Trussed up and forced to watch the burning fuse that will kill them

Nashaat Mahmood, 22, and Haidar Assad, 21, were both executed in an explosion meant to demolish a damaged building.

The young men - whose crime is not known - were tied up and placed in amongst the rubble, alongside the burning stick of dynamite so when the building finally blows up, they are killed. 

The video is once again trussed up to look like something for a Hollywood spy thriller, or video game, concealing some of their evil intent behind a glossy exterior.

 It begins with what looks like a pretend drone shot, taken from the sky and apparently zoning in on the two men.

The men's details are then flashed up across the screen, like they are characters being introduced in a computer game.

The reality is far worse: the two men have angered to despotic regime, and are to pay for it with their lives. 

According to the video, they were Shiite spies. ISIS are Sunni. 

It then cuts to a partially demolished building, believed to be somewhere in Anbar province.

The men are then led to the ruins, which seems to have been damaged in an airstrike, and made to sit in the middle to await their deaths.

The final moments of the video show the men's bodies, proving they are dead.
