Watch: ISIS vows to kill all agents cooperating with 'Western Crusaders'

ISIS delivered a message to Western agents: "Even if you develop your information security and convince yourselves that you will never be overcome, you will never get away from us."

ISIS has vowed to kill all the agents who collect information for the Western coalition's campaign against it, delivering a direct message to the West that it will never succeed in infiltrating into the organization.
A video titled "Running away would not help you," released Tuesday by IS’ province in Deir ez-Zor, shows the terror organization killing two alleged spies by blowing up the building where they stayed.
In the beginning of the video, ISIS delivered a message to Western agents: "Even if you develop your information security and convince yourselves that you are protected and you will never be overcome, you will not get away from us." 
"You do not fight us – you fight against almighty Allah who knows and sees everything. Where would you hide?"
With images of US President Barack Obama lighting on fire in the Oval Office at the White House presented in the background, ISIS threatens spies: "If you help the Crusaders for the money, know that Allah will foil the apostates' conspiracy against us."
"We are killing you in every possible way, and we have additional means to do so."
The two alleged spies talking in the video said they have provided the anti-ISIS Western coalition with pictures of ISIS activists and bases in Syria as well as information on ISIS’ relations with local citizens under its control. They claimed that they spied for the West because they were offered good payment and suitable working hours.
The video ends with sophisticated retaliation by ISIS against the two alleged spies. After presenting an aerial image of the building taken in January 2013, probably by one of the spies captured, an ISIS fighter is seen blowing up the building where the two stayed by pressing a button on a cellphone.
In this video, ISIS not only mocks the spies by using the images they have taken to document their killing, but also ridicules the West, using the same method of killing against its spies as it has been using against ISIS fighters in Syria in its aerial campaign.
