A suicide bomber struck an education centre in a Shiite area of the Afghan capital on Friday, killing 19 people and wounding 27, a Taliban-appointed spokesman for the Kabul police chief said.

The explosion inside the centre in the Dashti Barchi neighbourhood of Kabul populated mostly by members of Afghanistan's minority Shiite community took place in the morning hours, said the spokesman, Khalid Zadran.

The victims included high school graduates, both girls and boys, who were taking a practice university entrance exam when the blast went off, Zadran said. The centre is known as the Kaaj Higher Educational Centre and helps students prepare and study for college entrance exams, among its activities.

Zadran said education centres in the area will need to ask the Taliban for additional security when they host events with big gatherings, such as the study prep on Friday.

The suicide bombing was the latest in a steady stream of violence since the Taliban seized power. No one immediately claimed responsibility for the attack

The Islamic State group the chief rival of the Taliban since their takeover of Afghanistan in August 2021 has in the past targeted the Hazara community, including in Dashti Barchi.

Our teams have dispatched at the site of the blast to find out more details, Abdul Nafi Takor, a Taliban-appointed spokesman for the Interior Ministry, said earlier.

The US charge d'affaires for Afghanistan, Karen Decker, condemned the attack in a tweet.

Targeting a room full of students taking exams is shameful; all students should be able to pursue an education in peace & without fear," she said. We hope for a swift recovery for the victims & we grieve with the families of the deceased.

Afghanistan's Hazaras, who are mostly Shiite Muslims, have been the target of a brutal campaign of violence for the past several years, blamed on the regional affiliate of the Islamic State group. Militants have carried out several deadly attacks in Dashti Barchi, including a horrific 2020 attack on a maternity hospital that killed 24 people, including newborn babies and mothers.
