Baghdad Security Districts:
The southern provinces of Maysan, Dhi Qar, Muthanna, and Basra are populated almost entirely by Shi’a Arabs, in the major cities of Amarah, Nasariyah, and Basra, as well as in the rural marshlands. Of these provinces, Basra is the primary economic hub.
The mid-Euphrates region of Iraq lies south of Baghdad. Its main cities include Karbala, Hillah, Kut (الكوت), Diwaniyah (الديوانية), and Najaf (النجف). The population is predominantly Shi'a in the south and generally a mixture of Sunni and Shi'a to the north of Hillah and northwest of Kut. Iraqi Security Forces (ISF) play an important role in this region, particularly the 8th Iraqi Army Division led by the capable General Othman Ali Ferhood.
The Iraqi province of Diyala lies to the north of Baghdad. Its shares its eastern border with Iran, its northern border with Kurdistan, and its western border is shaped by the flow of the Tigris River. The Diyala River, a tributary of the Tigris, flows south through Diyala before meeting with the Tigris just south of Baghdad. Diyala's main cities include Baqubah (its capital), Muqdadiyah, Balad Ruz, Khalis, and Khanaqin. The province has a mix of Sunni Arab, Shi'a, and Kurdish residents.
