An explosion happened outside an educational center in Pul-e-Khoshk area of Dasht-e-Barchi in the west of Kabul on Saturday evening, killing 18 people, the Ministry of Public Health said.
The ministry said 48 others were wounded in the explosion.
The Interior Ministry said that the suicide bomber was recognized by security guards of the educational center and detonated his explosives before reaching his target.
No group has claimed responsibility for the attack. Taliban rejected involvement in the attack.
The Kawsar educational center is located in a narrow street. The suicide bomber who was trying to enter the center was reportedly recognized in the middle of the street in the west of Kabul, according to eyewitnesses.
Eyewitnesses said dozens of students were in their classes when the attack happened. Videos on social media following the attack showed many teenagers who sustained injuries in the explosion.
A similar explosion happened in the west of Kabul in 2018, killing 48 students.
Abdullah Abdullah, head of the High Council of National Reconciliation in a statement condemned the suicide attack on a training center in Kabul, saying it is inhuman and against Islamic principles and values.
Sharhzad Akbar, the chairperson of Afghanistan Independent Human Rights Commission said “after a week of horrific violence across Afghanistan” the news on the attack “drains every last ounce of energy and hope.”
The attack happens amidst a sharp increase in violence across Afghanistan. At least eight civilians were killed in a roadside bomb blast in Ghazni city, south of Kabul, on Saturday. Meanwhile, six security personnel who were protecting the Kamal Khan dam in Nimroz province were killed in an attack by militants, according to local officials.
Pakistani envoy Mohammad Sadiq said Pakistan “condemns in the strongest possible terms the inhuman terrorist attack outside an educational center in Kabul.”
