ISIS forces children to execute people
Shocking pictures exposed two boys aged about 12 shoot prisoners in the head, Daily Mail.
The men were forced to kneel on the ground close to a wooded area in northern Iraq as two boys aim handguns at their heads.
The children were dressed in military outfits and had been given gun holsters and green hats for the execution.
The two prisoners were reportedly accused of being "crusader spies."
Pictures also show them, dressed in orange jumpsuits, lying dead on the ground.
