A new ‘execution’ video features rebel Syrian fighters forcing ISIS captives to kneel in the dirt at gunpoint – only for them to do something completely unexpected.

Mirroring the slick production values of ISIS propaganda video, the footage opens with captives being led along a dusty road in orange jumpsuits by men in balaclavas.

The captives- some apparently in their teens – are then forced to kneel in the dirt while the members of the al-Shamiyya Front (a coalition of northern Aleppo-based rebel factions) proudly display their pistols.

They then point the weapons at the back of the militants’ heads.

It appears the ISIS fighters are about to die in yet another harrowing execution video from the war-torn region.

Suddenly a message flashed up on the screen: “Muslims are not criminals.”

Astonishingly, the masked men holster their weapons and walk away.

Another rebel then appears and lectures the jumpsuit clad ISIS militants on justice – powerfully showing them the mercy the terror group has denied to so many of its victims.

Sheikh Mohammed Khatib, President of the Sharia Office of al-Shamiyya, says: “To the champions of our revolution and the hope of our people, justice will guide us, Islam needs us.”

” We have allowed you a way out… we do not seek any fame”

“If you desire to execute us, here are our swords, such executions will only consolidate our faith.

“Kindness is the premise of our lives”

The men are then apparently imprisoned for their sickening crimes.
