The death toll from the suicide attack Saturday in Afghanistan's capital has risen to at least 18 killed and 57 people wounded, including students, the interior ministry said.
The explosion struck outside an education center in western Kabul.
Interior Ministry spokesman Tariq Arian said that the attacker was trying to enter the center when he was stopped by security guards.
According to Arian, the casualty toll may rise further as family members of victims of the suicide bombing are still searching the several different hospitals where the wounded have been taken.
No group claimed immediate responsibility for the bombing. The Taliban rejected any connection with the attack.
An ISIS affiliate claimed responsibility for a similar suicide attack at an education center in August 2018, in which 34 students were killed, The Associated Press reported.
Earlier Saturday a roadside bomb killed nine people in eastern Afghanistan after it struck a minivan full of civilians, a local official said.
