The world's most notorious terrorist group ISIS, last weekend released a video showing the mass executions of prisoners.
This massacre is termed to be the biggest and most sickening of their executions as men in their hundreds were made to lay in shallow graves and were then sprayed with bullets.
The men are believed to be military cadets captured during their battle with the terrorists.
The men were brought to their death place in trucks and were heard in the video pleading for their lives before they were killed.
Some were even shot individually and their bodies dumped into the Tigris River, while an excavator is seen shifting piles of bodies as the executions continue into the night.
