The crash on the Kandahar-Herat highway involved a motorcycle, a fuel truck and a bus, said Sher Mohammad Wahdat, head of the information department for Helmand's provincial government, adding 38 people were injured.

Photos in local media showed a tanker on fire on the dusty road and the wreckage of vehicles from the accident, which occurred in the Gereshk district of Helmand.

Traffic accidents are common in Afghanistan, with poor infrastructure exacerbated by decades of war that ended when foreign troops left in 2021 and the Taliban took over. Southern Helmand province, a Taliban stronghold during the war, saw some of the country's most intense fighting.
