At least 19 students were killed, and several wounded when a suicide bomber detonated himself among students inside an educational institute in west Kabul.
Khalid Zadran, Taliban's Kabul Police spokesman, said that preliminary information shows that 19 people lost their lives and 27 others were injured.
The attack took place at around 7 a.m. local time.
"It was a powerful one and was heard in distant areas of Dasht-Barchi," an eyewitness said.
Eyewitnesses said that the suspect entered Kaaj Academy in Kabul's Hazara-dominated PD-13 area after he killed the security guards. Videos shared by locals show dead bodies and injured people at the scene.
"We hope that the educational centers will always inform the local police about their special programs," Zadran added.
Many eyewitnesses confirmed to Etilaatroz that the number of victims is more than 60, mostly girls.
A representative of the academy told Zan Times that a preparatory exam was scheduled for today with over 300 students in attendance.
The Taliban has confirmed the blast but offered no further details.
Last Friday, at least seven people were killed and 41 injured in an explosion near a mosque in Kabul.
