Western Iraq is comprised of a single province, Anbar, located to the west of Baghdad. It stretches northwest to the Syrian border and southwest to the Saudi Arabian border.

Moving from west to east, the cities of al-Qaim, Rawah, Haditha, Hit, Ramadi, Habbaniyah, and Fallujah make up the main population centers of the province. Anbar’s population is almost entirely Sunni Muslim.
