Islamic State has released a video which shows a young boy being forced to execute a prisoner.
The boy, who's blonde and appears to be of European origin or descent, is shown lifting the gun from the holster, with a man dressed in army camouflage aiming it.
Then, holding the boy's hands around the gun, he's shown pointing it at a blindfolded prisoner.
Earlier this week, footage was broadcast by Isis which showed brainwashed youngsters detailing their dreams of becoming 'martyrs'.
The school-age children are called "the cubs of the caliphate" by a narrator and they are hailed as part of "the generation that will conquer Damascus, Baghdad, Jerusalem, Mecca, Al-Medina, Dabiq, Rome and Andalusia".
Isis has recruited thousands of children, abducted to convert them into suicide bombers or killers.
