Answer: Kabul River
Notes: Afghanistan has announced plans to construct a dam on the Kunar River, blocking its flow into Pakistan. The Kunar River is a major tributary of the Kabul River, which later merges with the Indus River in Pakistan. The river originates from the glaciated Hindu Kush Mountains in Chitral, Khyber Pakhtunkhwa, Pakistan. It flows into Afghanistan and joins the Kabul River there. The two main tributaries of the Kunar River are Bashgal (Landiasind) River and Pech River. The proposed dam may affect water flow and relations between Afghanistan and Pakistan.
