KABUL: A bomb blast on a minibus killed at least four people and injured several others in the Afghan capital on Saturday, police said.

The explosion in an eastern district of Kabul was the latest in a series of deadly attacks that have rocked Afghanistan in recent months, a little under a year since the Taliban takeover.

A team of Taliban security personnel had been deployed to the area to investigate the bombing, police spokesman Khalid Zadran told AFP.

No group has so far claimed responsibility for the bombing that occurred in a district mainly inhabited by members of the Sunni Pashtun community.

Four bombs kill at least 16 in Afghanistan

While the number of bombings has fallen across the country since the Taliban seized power in August, attacks have ticked up recently.

Dozens of civilians were killed in Kabul and other cities in primarily sectarian attacks during the holy month of Ramadan, which ended on April 30 in Afghanistan, with some claimed by the Islamic State group.

Many of those attacks targeted the Shiite Hazaras and Sufi communities.

Some of the bombings struck minibuses ferrying passengers from offices or markets to their homes.

But the deadliest attack during Ramadan came in the northern city of Kunduz, where a bomb targeting Sufi worshippers tore through a mosque on April 22.

At least 33 people were killed in that blast and scores more were wounded.

The regional branch of IS in Sunni-majority Afghanistan has repeatedly targeted Shiites and minorities such as Sufis, who follow a mystical branch of Islam.
