Video shows Syrian rebel group executing 18 ISIS fighters

A Syrian rebel group operating around Damascus has executed 18 alleged members of the Islamic State of Iraq and al-Sham (ISIS) in a video mimicking the extremist organization's own productions. The video, which emerged overnight, shows fighters from Jaysh al-Islam wearing the orange prison clothes that ISIS victims often sport. The ISIS prisoners however are wearing black clothes and chained together wearing ankle and hand shackles with metal balls attached. The nearly 20-minute production mimics many aspects of ISIS's own execution videos, with similar sound effects and visuals.
