Police report says 19 people were killed and 27 injured in a suicide bombing at an educational facility in Kabul, the capital of Afghanistan, authorities reported on Friday.
According to Khalid Zadran, the Taliban-appointed spokesman for the chief of the Kabul police, the explosion took place inside the centre in the Kabul suburb of Dashti Barchi.
The incident was not immediately attributed to anyone.
The Hazara ethnic minority has been a target of earlier attacks carried out by militant groups like Islamic State, among others, and many people residing in the western region of the area where the blast happened are Hazara.
Speaking on behalf of Kabul police, Khalid Zadran told Reuters that "a blast took happened inside an institute" and "the incident has [caused] injuries." He stated that security personnel had arrived to conduct an investigation.
Under the condition of anonymity, a witness told Reuters that a suicide bomber had set off explosives at a school.
"Attacking civilian targets reveals the enemy's barbaric depravity and lack of moral norms," interior ministry spokesman Abdul Nafy Takor tweeted.
Bloodied victims were seen being transported from the site in videos that were shared online and images that were released by local media, according to AFP.
Twenty-four people, including teenage students, were killed in an attack in 2020 at a school in west Kabul that was claimed by Islamic State.
The Taliban have emphasised that they are safeguarding Afghanistan after decades of war ever since they took control of the country in August 2021, but recent months have seen a string of explosives at mosques and in civilian areas.
