The disturbing clip shows the UK-backed Nour al-Din al-Zenki terrorists in the back of a truck with poor lad – who they accuse of being a spy.
The young boy is said to be a soldier for Liwaa al-Quds – a group which supports Syrian Government Bashar al-Assad and Syrian army.
He is seen in the back of a truck in the Palestinian refugee Handarat Camp in northern Aleppo.
One of the group terrorist mercilessly slaughtering the child. The boy can been seen in ragged clothes and surrounded by the smug militants.
One of the terrorist holds his hair and another slaps him in the face.
Faced down on the back of the truck with his hands bound, the boy appears to have been tortured – before his throat is slit by a small knife.
The Nour al-Din al-Zenki group is part of the Levant Front, made up of the Islamic Front and the Free Syrian Army – who are fighting to overthrow the Assad government.
The video is too horrific to be shown, Mirror Reports.
