At least 19 people have been killed and dozens more wounded after an education institute in the Afghan capital of Kabul came under attack on Friday.
Many of those living in the western area where the blast occurred are Hazara, an ethnic minority targeted in past attacks launched by militant group IS, among others.
Kabul police spokesperson Khalid Zadran said that 27 people had also been injured in the attack, revising the number of wounded down slightly from the 29 announced earlier.
He said the attack took place at an education institute where an entrance exam was taking place.
Schools are normally closed in Afghanistan on Fridays.
"Attacking civilian targets proves the enemy's inhuman cruelty and lack of moral standards," he said, without specifying who they believed was behind the attack.
No group has claimed responsibility for the attack yet.
Since taking over Afghanistan in August 2021, the Taliban have emphasised that they are securing the nation following decades of war, but recent months have seen a series of blasts at mosques and civilian areas.
