March 16, (Al Jazeera) - At least 21 people have been killed and 38 others injured after a bus collided with an oil tanker in the Gerashk district of Afghanistan’s Helmand province, officials said.

The crash on the Kandahar-Herat highway involved a motorcycle, a fuel truck and a bus travelling from Herat city to the capital Kabul, said Sher Mohammad Wahdat, head of the information department for Helmand’s provincial government.

The bus driver lost control after colliding with the motorcycle and crashed with an oil tanker travelling in the opposite direction from the southern city of Kandahar to Herat, sparking a fire.

“On Sunday morning, 21 people were killed and 38 people were injured due to a collision between a tanker, a motorcycle and a passenger bus,” the provincial information department said in a post on X.

An investigation into the accident was under way, said Qadratullah, a traffic official in Helmand.

Helmand police chief spokesman Hzatullah Haqqani said 11 of the 38 injured people were transferred to hospitals with serious injuries.

Images shared by the information department on social media showed charred, twisted metal scattered across the highway and the crushed cabin of the tanker.

Cleanup crews were on site removing the debris, according to officials.

Traffic accidents are common in Afghanistan, mainly due to poor road conditions and driver carelessness.

The country’s low-lying roads and lack of traffic signs are also drivers of road accidents.
