At least 19 people were killed and wounded dozens in a suicide attack at an education institute in the Afghan capital Kabul.
Police said that there was no immediate claim of responsibility for the blast on Friday.
Many of those living in the western area where the blast occurred are Hazara, an ethnic mostly Shia minority targeted in past attacks launched by the ultra-radical Islamic State and others.
The official death toll is likely to rise. A hospital source said 23 people had been killed. A Taliban source said 33 people had been killed and that female students were among the casualties.
Since taking over Afghanistan in August 2021, the Taliban have emphasised that they are securing the nation following decades of war, but in recent months there have been a series of blasts at mosques and civilian areas.
Teenage students were among the 24 people killed in a 2020 attack claimed by Islamic State at an education centre in west Kabul.
