KABUL: A series of explosions at a high school and educational center in Kabul on Tuesday killed at least six people and injured many more, including students, police and health authorities said.

Two blasts occurred at the Abdul Rahim Shaheed High School in the capital’s western neighborhood of Dasht-e-Barchi. A nearby tuition center was also targeted in a grenade attack.

“According to initial figures, six of our compatriots were martyred,” Kabul police spokesperson Khalid Zadran said in a statement. “An investigation has been launched into the attack.”

The Ministry of Public Health said at least 20 people were injured.

Abdul Naser, an eyewitness, said the victims were mostly students.

“There was smoke all over the area following the blasts,” he told Arab News. “All casualties were young boys in their teens. We were all so scared.”

The city’s Emergency Hospital, which received some of the wounded, told the media all of them were between the ages of 16 and 19.

There has been no immediate claim of responsibility for the apparent attack and it is possible the death toll could rise.

In May 2021, there was a bombing at the Sayed Al-Shuhada girls’ school in the same area of the Afghan capital, which is home to a large Shiite Hazara community.

The attack killed at least 85 people, mostly teenage girls, as the students were leaving classes to break their Ramadan fast.
