At least one civilian was killed and six others were wounded in an explosion in a Hazara-dominated area in the western part of Kabul city, a hospital source says.
A doctor in the Hakim Nasir Khesrow Balkhi local hospital said that two of the wounded people were in critical condition when they were admitted to the hospital.
There are reports that several wounded people had been taken to other nearby hospitals.
Taliban government chief spokesman Zabihullah Mujahid said in a statement that the blast occurred apparently after a fire broke out in a minibus and resulted in an explosion that killed one civilian and wounded two others.
“Investigation into the incident is ongoing,” Mujahid added.
A witness from the Shi’ite Muslim majority enclave told DPA that the blast was caused by a magnetic bomb attached to a passenger minibus.
Social media images show a huge fire and a plume of smoke rising above the city.
There was no immediate claim of responsibility for the blast.
Western Kabul has experienced regular bombings that are usually claimed by the Islamic State group.
It is the first explosion that has occurred in the neighbourhood since the Taliban took over leadership of the country earlier this year.
