There has been serious conflicts between two neighbouring nations regarding the sharing of water from this river. Identify the river from the following :

The Helmand River (also known as the Hirmand) is the longest river in Afghanistan, perfectly matching the description provided:

• Origin: It originates in the Sanglakh Range of the Hindu Kush mountains, west of Kabul.
• Course and Destination: It flows for approximately 1,150 km before draining into the Hamoun wetlands (Hamun-e-Helmand), a seasonal endorheic lake system on the border of Afghanistan and Iran.
