Child executioners are shown in a new chilling execution video from the historic city of Palmyra in the Syrian desert. The young executioners-in-training in the video brutally killing a group of more than 25 regime soldiers who are lined up on their knees on the stage of the Roman amphitheater. The beautiful Greco-Roman ruins, listed as a UNESCO World Heritage Site, were once used for festivals. This time the amphitheater is covered in blood as the child murderers learn their trade.

Spectators look on as the execution takes place as though it were a performance rather than real death of people condemned for being government supporters.

ISIS is known for using children as ‘caliphate cubs’ for suicide missions and other activities. Over recent weeks more than 500 children have been kidnapped and there are fears that these children will be brainwashed into joining the group’s ranks and be trained to take part in terror attacks.
