Militants fighting for the Islamic State terror group in Syria and Iraq have released a video they claim shows Jordanian pilot Maaz al-Kassasbeh being burnt alive while locked in a cage. The footage, which is titled 'Healing the Believers Chests' appears to show the captured airman wearing an orange jumpsuit as a trail of petrol leading up to the cage is seen being set alight. Flames are seen quickly spreading to the cage where they completely engulf the helpless pilot in images that are far too distressing to publish.
