At least 19 people were killed and 32 others injured when a fuel tanker burst into flames in a tunnel north of the Afghan capital Kabul, a local official said on Sunday.
The Salang tunnel – located between the provinces of Parwan and Baghlan – is about 2.67 kilometers long and was built in the 1960s. It is a vital link between the north and the south of the country.
A Parwan provincial spokesman, Hekmatullah Shameem, said the tanker caught fire in the Salang tunnel on Saturday night.
Rescue teams are working at the scene of the incident and there are fears the death toll could rise, he added.
The cause of the fire was not immediately clear.
