In the latest shocking act of brutality by ISIS, the jihadist group recently published a video showing a young child beheading a prisoner in Syria.

The child is dressed in black fatigues and identified as one of the so-called "Cubs of the Caliphate" - a term used for child soldiers recruited, indoctrinated and trained by ISIS at special youth camps.

In the gruesome video the captive - apparently a Syrian army officer - is forced to lie on his stomach in front of the child, who then stands over him and saws his head off with a small knife. The young executioner then calmly places his victim's severed head on his dead body, while staring menacingly into the camera.

The video claims the execution took place in Syria's Hama province.

As in previous videos involving child executioners, an adult ISIS terrorist stands by and observes the grisly spectacle throughout.

The officer is believed to have been stationed in the ancient city of Palmyra, which was recently captured by ISIS after heavy fighting.

Following Palmyra's capture the jihadists destroyed several ancient artifacts, and conducted a brutal public mass-execution in the city's ancient Roman amphitheater. That slaughter was also carried out by child soldiers, seemingly all in their early-to-mid teens.

Although the latest video is being feted as the first of its kind, a similar video back in March also showed ISIS child executioners beheading captives.
