The dreadful video shows at least eight civilians gathered in a building by ISIL militants who then shoot them at close range.
The militants, who don's speek Arabic and seem to be from Chechnya, remain indifferent to the victims begging not to kill them.
An old man and a young boy are among the victims, while a number of dead bodies already lie on the ground.
Location of the crime is not identified in the video but some media reports said it was in Deir ez-Zour.
The ISIL has been killing Syrian civilians and many army soldiers, some in very vicious ways, using the extensive support given by the US and its allies to the massive war which has been ripping Syria part for more than three years.
The group which first entered as al-Qaeda’s representative was later disbanded by the terrorist group leader Aymen Zawahiri and replaced with al-Nusra Front.
