Kabul River, or Kabal River (Persian: دریای کابل), is a river that rises in the Sanglakh Range in Afghanistan, separated from the watershed of the Helmand by the Unai Pass. It is the main river in the eastern part of Afghanistan. It flows 700 km before joining the Indus River near Attock. It passes through the cities of Kabul, Chaharbagh, Jalalabad, and (flowing into Pakistan some 30 km north of the Khyber Pass) Nowshera. The major tributaries of the Kabul River are the Logar, Panjshir, Kunar and Alingar and Bara rivers.
