The Indus is a transboundary river of Asia and a trans-Himalayan river of South and Central Asia. The 3,180 km river rises in mountain springs northeast of Mount Kailash in the Western Tibet region of China, flows northwest through the disputed region of Kashmir, bends sharply to the left after the Nanga Parbat massif, and flows south-by-southwest through Pakistan, before emptying into the Arabian Sea near the port city of Karachi.
