The Dulaimi-ISIS alliance quickly drew support from other Sunni tribes as well as from a shadowy organization of former Baathists known as the Naqshbandi Order. The Sunni pact waged seesaw battles with army troops for several weeks for control of Ramadi and five other cities, but an uneasy truce settled over Fallujah, with ISIS firmly in charge of the center of town. It was the first time the terrorist group could officially claim an Iraqi city as its own.
