Wow! ISIS 'gun down 200 Syrian children' in horrifying mass execution video

Sickening new footage shows ISIS terrorists gunning down 200 Syrian children in a savage mass execution. The video, which was circulated online by a Yemen-based anti-ISIS activist, shows the children bound and forced to lie face down in a line. The killers then open fire with automatic rifles.

The authenticity of the video has not been confirmed, but the terror group's slick propaganda team is known to film their barbaric executions and circulate them. Islamic State is also known to have executed children in the past.
