"At least 10 bus passengers were killed and around 40 were wounded in an accident on Saturday on the Kabul-Baghlan highway," a Baghlan security department spokesman said, as quoted by the TOLOnews broadcaster.
The incident occurred in the Malkhan area of the Salang Pass, according to the spokesman.
The Salang Pass is the primary mountain pass, located in the Hindu Kush mountains. The 2.67 kilometers-long (1.65 miles) Salang Tunnel, which runs underneath the pass, was completed by the Soviet Union in 1964. The tunnel connects northern Afghanistan with the capital city of Kabul and southern parts of the country.
