The document was purportedly issued in May by ISIS’ Fallujah province and was recently obtained by the Iran-backed Popular Mobilization Units in the city of Karamah, located 16 kilometers northeast of Fallujah.

In the document, ISIS’ leadership in the war-ravaged Fallujah explains to the organization’s jihadists how to prepare for the upcoming battle for the city.

“You should plant explosives in the city’s houses, mosques and squares, and blow them up before the Shi’ite Popular Mobilization Units and the apostate Iraqi army enter the city. You should spread photos of these explosions and present them as Shi’ite attacks that aim to take revenge against Sunnis,” ISIS’ leadership in Fallujah stated.
