Mosul is a major city in northern Iraq. Located some 400 km (250 mi) north of Baghdad, Mosul stands on the west bank of the Tigris, opposite the ancient Assyrian city of Nineveh on the east bank. The metropolitan area has grown to encompass substantial areas on both the “Left Bank” (east side) and the “Right Bank” (west side), as the two banks are described by the locals compared to the flow direction of Tigris.
