Kabul , Afghanistan ( CNN ) -- A Taliban-affiliated website has released video that purports to show suicide bombers who targeted Kabul 's Intercontinental Hotel in June preparing for the attack in the hills and studying a tiny model of the hotel in detail . The video -- released on a Taliban-affiliated website in the past few days -- is an hour long . It includes testimony and footage - -even gymnastics -- from the seven attackers who killed 11 more people when they laid siege to a government conference at the hotel for six hours . The attack -- one of the most brazen and penetrating to hit the capital -- was eventually suppressed by special forces , helicopters and a drone . One of the apparent suicide bombers , Naseer Ahmad Anas , speaks of his motivation to take his own life and that of others . `` My message is life is too short , '' he says . `` You can die of cancer , or a car accident . If you want God 's blessing , be a suicide attacker . '' CNN can not prove the authenticity of the elaborate video . The images also show masked and uniformed men training in the hills , the exercises they undertake clearly designed to show they are a more disciplined force than parts of the Taliban have been in the past . In one scene , they appear to attack an Afghan military vehicle , killing the troops and stealing their weapons and uniforms . The footage is undated and the mountainous location where it was shot is unclear . The hotel attackers are also filmed in a room sitting in a circle , surrounding a realistic mock-up of the Intercontinental Hotel . A tutor , whose face and voice are not discernible , offers tactical tips for the assault . `` Those of you with machine guns and rocket-propelled grenades , get on the roof and use it as a control tower , so the enemy ca n't enter easily . '' The video shows footage of the attack obscured by darkness , but the tracer fire of the attackers , and their NATO and Afghan opponents is visible . The attack caused considerable concern in Kabul , the first of several attributed to the Haqqani network that penetrated the capital 's so-called Ring of Steel . The video is possibly also the first detailed glimpse of a part of the insurgency that is rapidly becoming America 's main opponent here . The Haqqani network , a group of militants active in Afghanistan 's east but accused of receiving sanctuary and logistical support in Pakistan , were blamed for the Intercontinental Hotel attack and some observers have suggested the pictures are in fact a rare insight into the network . The insurgent group -- which is linked to the Taliban but often considered a more sophisticated and independent adjunct to it -- has rarely been filmed .
The hour -long video was released on a the Intercontinental Hotel -affiliated website . The attack was one of the most brazen to hit America . The video includes testimony and footage from 11 attackers who killed seven at Taliban .
