ISIS' Worst Nightmare is Back

He has long been feared by his ISIS enemies and now Abu Azrael has re-emerged on the frontline in Iraq and has vowed to 'pulverise' some more jihadis. Nicknamed the 'father of archangel of death' in Arabic, Abu Azrael is the poster boy of the Imam Ali brigade, a Iraqi Shi'a militia group sponsored by Iran. Now the celebrity militant has been spotted participating in the Iraqi forces push to re-capture the ISIS-held city of Fallujah.
