In which modern-day country is the site of the ancient city of Nineveh?

Nineveh was an ancient Assyrian city of Upper Mesopotamia, located in modern-day northern Iraq; it is on the eastern bank of the Tigris River, and was the capital of the Neo-Assyrian Empire. It was the largest city in the world for some fifty years until, after a bitter period of civil war in Assyria itself, it was sacked by an unusual coalition of former subject peoples, the Babylonians, Medes, Persians, Chaldeans, Scythians and Cimmerians in 612 BC. Its ruins are across the river from the modern-day major city of Mosul, in the Ninawa Governorate of Iraq. The two main tells, or mound-ruins, within the walls are Kouyunjik (Kuyuncuk), the Northern Palace, and Tell Nabī Yūnus.
