ISIS has released a significant new execution video from the historic city of Palmyra, in the Syrian desert.
Child executioners are shown in the video being forced to brutally slaughter a group of more than 25 regime soldiers.
The video shows the soldiers lined up on their knees on the stage of the Roman amphitheatre, which had formerly been used for an annual festival in the city.
A baying crowd of men and boys gathered in the restored ruin waiting for the slaughter, many wearing military uniforms and headscarves.
On a command, the condemned soldiers are killed simultaneously with a shot to the head.
ISIS captured the historic city on May 21, and has been systematically destroying the city’s treasured ancient monuments.
The group was accused of executing hundreds of people in and around Palmyra since it swept into the city in May, after a lightning advance across the desert from its stronghold in the Euphrates Valley to the east.
