Eye For Eye: Rival Syrian Terror Group Executes ISIS Fighters In New Video

A rebel group battling ISIS in Syria has turned the tables on its enemies by capturing and slaughtering dozens of Islamic State soldiers on camera.

A rival Islamist rebel group, Jaysh Al-Islam battling ISIS in Syria has turned the tables on its enemies by capturing and slaughtering dozens of ISIS fighters in new photos and video gone viral. Dressed in orange jumpsuits, the Islamic soldiers lead 13 shackled ISIS jihadis to their deaths.

Jaysh Al-Islam calls itself the 'Army of Islam' and reportedly commands as many as 25,000 loyal fighters following the merger of around 60 rebel factions inside Syria.

The ISIS fighetrs dressed entirely in black were given something to drink before each of their faces are clearly shown in the 19 minute-long propaganda video. The commander announces: 'Allah did not make a disease without appointing a remedy to it.' They are then shot in the back of the head at point blank range with shotguns.

Before they are killed, a Jaysh Al-Islam militant says:

'The most serious calamity for our jihad today is a group of people who grow at a time of division among Muslims. This group claimed to be the mother state and made Takfir [accused of apostasy] on other Muslims, shed their blood and looted their properties and dignities.

They worsened... the ordeal of Muslims by corrupting their religion and livelihood and killing the jihadi leaders who did their best to help our stricken nation. They wreaked havoc on our people in liberated areas and cut the supply route of jihadis. They left... Tehran intact and instead they attacked our mosques. This is the penalty for what they have committed. We also call on their fellows to repent.'
