ISIS has released a sickening video showing them execute a prisoner in Afghanistan - where it is embroiled in a bloody war with the Taliban. In the footage, released by the slick propaganda machine of ISIS, men in desert combat gear and masks are seen drilling with rifles and engaging in hand-to-hand combat at a camp in the war-ravaged country. At the end of the propaganda film, a column of men are seen leading a prisoner, clad in the terror group's trademark orange jumpsuits, to the final place the man will ever see. After a speech, the leader pulls a handgun and - harrowingly - the prisoner turns around to say something and twists to get away. However, the murderous jihadi pulls the trigger then shoots him on the ground in scenes far too harrowing to show. In slickly-produced propaganda videos, Islamic State urges the people of Afghanistan to join their ranks and accuse the Taliban of working with their mortal enemy Iran. The Afghanistan-based jihadis have been in a series of clashes with ISIS as they struggle for control of Nangarhar province, which borders Pakistan. ISIS has released a series of bloody execution videos - which even the Taliban has blasted as extreme. Although the Taliban controls or threaten around one third of Afghanistan, according to US estimates, some militants have shifted their allegiance to Islamic State, which has begun challenging Taliban units in pockets of the country. There is along tradition of mistrust between Pashtun Muslims and Arab Muslims and the Taliban, which seeks political and military power in Afghanistan sees ISIS as a threat to its ambitions. Hundreds of fighters for both sides have now been killed in fighting, creating an even more toxic environment in Afghanistan
