The United Nations has confirmed terrified families are being brutally shot by terrorists in Bakir, a small neighbourhood in east Mosul.
Sources suggest jihadis are transforming civilian homes into terror camps so they can defend themselves from Iraqi soldiers, who have killed more than 1000 ISIS militants and are close to regaining control of Mosul.
At least 12 civilians have been murdered for denying ISIS access into their homes, reports claim.
News of the brutal murders comes days after the terror group released a video titled, Explanation of How to Slaughter Disbelievers.
The professionally made film features a terrorist slashing the throat of a Christian victim, and a Kurdish soldier can also be seen exploding in the background.
During the harrowing 14-minute propaganda film, ISIS soldiers urged Muslims in Britain, USA and France to kill “disbelievers” in the name of Allah.
An armed terrorist featured in the video, said: “We must fight them. Even with the most basic equipment, they have kept crusaders sleepless and worried by fighting for ISIS.”
The explicit video also shows lifeless bodies of soldiers falling to the ground after they were executed from the back of their heads.
ISIS militants are also murdering people suggested of leaking information to Iraqi soldiers.
Anjou Choudhry, leader of ISIS, reportedly keeps his suicide vest on whilst sleeping in case he is caught by Iraqi soldiers.
