"Two civilians have been killed and three others were wounded" when a bomb exploded on a minibus in the Dasht-e-Barchi district of Kabul, the Taliban's interior ministry spokesman Sayed Khosti told reporters.

"In another explosion in the same area, one woman was wounded," he added, specifying that the second blast was also a bomb.

There was no immediate claim of responsibility for the attacks.

Dasht-e-Barchi is largely populated by the mostly Shiite Hazara community, who for years have been the target of violence by the jihadist Islamic State-Khorasan (IS-K) group.

In November, a similar bomb attack on a minibus in Dasht-e-Barch killed two people and wounded five others. That attack was claimed by IS-K.

The Taliban has vowed to crush this rival extremist group, launching crackdowns against hideouts used by the militants, especially in the country's south and east.

Friday's bus bomb is the first fatal attack reported by the Taliban for several weeks.

But Kabul has been hit by repeated blasts lately that the Taliban say have been non-fatal.

The Taliban came back to power after a two decade absence on August 15 when the previous government's resistance melted amid the final stages of a US military withdrawal from the country.

The Taliban's first stint in power lasted from 1996 to 2001, before a US invasion late that year toppled the Islamists.
