Released by the Al-Hayat Media center, a propaganda arm of ISIS, the video purportedly shows the boy killing two alleged spies with a handgun.
The authenticity of the video, released by SITE Monitoring Service, could not be verified.
The video begins with TV-style interviews with both men, who claim they are spies against the militant group and are working in Syria and Turkey. They also confess to attempting to infiltrate the terrorist group.
The video was titled “Uncovering an Enemy Within” and features two men who appear to acknowledge they work for Russian security services.
One of the men says he was recruited by Russia’s Federal Security Service to get close to an unidentified “Islamic State fighters.”
The men claim they were hired to gather information on the ISIS, Ekurd.net reports.
The slender youth with shoulder-length hair appears to be younger than a teenager. Near the end of the video, he purportedly executes the kneeling men with a pistol.
