Photos: ISIS Releases Video Of A Child Beheading A Syrian Army Captain

World's most depraved islamist terrorist group, ISIS has released a sickening video in which it used a child fighter to savagely behead a Syrian army officer in the first execution of its kind.

The murder is understood to have taken at the Western Hir Palace in the province of Homs after the soldier was captured by jihadists at the nearby Al-Bosayri army checkpoint. The unnamed officer is believed to have been a regime leader in the ancient city of Palmyra, which ISIS captured in May.

In the past, ISIS have increasingly used young boys in their gruesome executions, with some children no older than 12 being forced to shoot the opponents at point blank range.

The video ends with the Isis child soldier decapitating the Syrian army captain and putting the head over his lifeless body as an older militant turns to the camera and makes a chilling threat to the West. 'Our goal is not only Palmyra or Homs or Damascus, rather our goal is to conquer Bayt al- Maqdes [Jerusalem] and Rome, God willing,' according to the UK-based Syrian Observatory for Human Rights, who say they were sent a copy of the video.
