The video clip lasts a mere 35 seconds . It 's night . Six men , illuminated by a flashlight , are sitting with their hands tied behind their backs and with various types of blindfolds . More men huddle behind them in the dark . In front of them is a pit , apparently freshly dug , and on the other side of the pit sits another man similarly bound and blindfolded . Two seconds into the clip , someone says , `` Jahiz ? '' `` Ready ? '' At three seconds a man extends his right arm into the light , holding a pistol . At six seconds the first shot is fired into the back of the first man 's head . The man with the pistol moves decisively , without hesitation , shooting one after the other in the back of the head . It would appear he has done this before many times . Eleven seconds into the video clip , you can hear what sounds like open faucets . It 's the sound of blood gushing from the head wounds . And the gushing sound gets louder and louder . Twenty-six seconds after the first shot is fired , a total of 14 men -- some of whom appear to be teenagers -- are dead or dying , some slumping into the pit . This video clip was one of a variety recently obtained by CNN from Syrian activists . They document atrocities committed not by the regime of President Bashar al-Assad , but rather by members of the Islamic State in Iraq and Syria , known as ISIS , which emerged last year as a major power in opposition-controlled parts of northern Syria . In the areas controlled by ISIS , public floggings and executions have become commonplace . Most recently ISIS has battled other opposition groups in fighting that has left well over 2,000 people dead . Even Al Qaeda 's leader , Ayman Al-Zawahiri , has demanded ISIS leave Syria . The material CNN obtained provides a snapshot of the inner workings of ISIS , a group using methods and tactics not unlike those of the regime that Syrians rose up against almost three years ago . The material provided by the activists was found in a house in Aleppo occupied by one `` Abu Ahmed Al-Iraqi , '' or `` the Iraqi . '' As is so often the case with members of these radical groups , this is not his real name . He abandoned the video clips , as well as the camera they were shot with , when ISIS retreated from the area during fighting against other opposition groups . Activists describe Abu Ahmed as an `` amir , '' a commander , responsible for carrying out justice , ISIS style . He is , in effect , judge , jury and executioner . He appears to be the man who carried out the executions described above . The other clips include eight interrogations of men , most of whom are members of opposition factions not affiliated with ISIS , all operating in or around the town of Al-Bab , northeast of Aleppo . It 's not clear whether Abu Ahmed Al-Iraqi is doing the interrogations , but the strong Iraqi accent of the interrogators leaves no doubt about where they come from . No torture occurs on camera , but it 's clear the subjects are under duress . They are all blindfolded , and several sweat profusely . The line of questioning is persistent , always focusing on the activities and opinions of opposition members . Not once in the course of the lengthy interrogations is a single question posed about the Assad regime . In fact , it 's not even mentioned . There are veiled threats ; one of the men , who identifies himself as a doctor named Basil , is asked if he ever wants to see his two children again . Another young man , Mohamed , is told to speak the truth to `` save himself . '' He responds by saying , `` I will speak the truth , even if I lose my head . '' ISIS is clearly worried that many Syrians view them as unwanted interlopers . Thousands of young men have flocked from around the world , including Europe and North America , to join the fight against the Assad regime , and many of the more radical among them have joined ISIS and other jihadi groups . At one point the interrogator demands of the aforementioned Mohamed : `` Did n't people say ISIS are strangers ? That they wear `` chabounat ? '' Chabounat is a derisive term referring to the short jalabiyas , or robes , worn by hard-line Islamists to copy the attire of the Prophet Mohammed . Chabounat in this case might be the equivalent of petticoats . Mohamed wisely claims complete ignorance . From the video clips , it appears that Abu Ahmed has made a life for himself in Syria . In a series of clips he is instructing a young woman in a black coat how to use an AK-47 assault rifle and a pistol . Her face is exposed -- she is not wearing the `` niqab , '' which completely covers the face and has become de rigueur dress for women in areas controlled by ISIS . She speaks with a Syrian accent . He 's also getting around in a late-model black BMW SUV . And in another video clip , he is doing target practice in the garden of a high-walled villa . A fancy car , nice house , interrogations and mass executions : meet the new boss in this part of Syria . Same as the old boss .
Videos obtained by Islamic opposition activists show executions , interrogations . The ringleader , Abu Ahmed al-Iraqi , may be leader of Syrian State in Iraq and Iraq . ISIS is a jihadist group opposed to the regime of Syrian President Abu Ahmed al-Iraqi . Al Qaeda leader Bashar al-Assad calls for the group to leave Syria .
