What We Know About the Sham-e-Hedayat School Grenade Blast in Kabul

An explosion at Sham-e-Hedayat private school in Kabul’s western Dasht-e-Barchi neighborhood injured dozens of people as students were leaving on 17 August 2026. The strongest available UN-linked casualty figure is at least 42 children aged 9 to 14; earlier Afghan media reports put the total number of injured people as high as 52.

The blast has been identified as a grenade explosion, but the person responsible, the motive and the precise circumstances remain unresolved.

What happened at the school?

The explosion occurred at about 4:30 p.m. local time in the courtyard of Sham-e-Hedayat private school in Mahdia Township, in Dasht-e-Barchi’s District 13. Health sources cited by local reporting said students had been dismissed from their classes when a grenade was allegedly thrown from a narrow alley opposite the school into the courtyard.

That account describes the reported trajectory of the grenade, not a confirmed reconstruction of the attack. Afghanistan’s Directorate of Mine Action Coordination reportedly examined the scene and confirmed that a grenade had exploded, consistent with information attributed to Kabul police.

How many children were injured?

Casualty figures varied in the first reports:

• Local reports cited totals of up to 52 injured people, most of them children.
• UN reporting later identified at least 42 injured children between 9 and 14 years old.
• Kabul police spokesman Khalid Zadran initially said only that “a number of children” had been wounded and that an investigation was under way.

The difference may reflect changing early counts, different definitions of the affected group or separate reporting from hospitals and witnesses. The UN’s age-specific figure is the clearest later assessment available in the supplied reporting, but it does not necessarily settle the broader total of injured people.

Who has been blamed?

No group had claimed responsibility in the reporting reviewed.

Taliban spokesman Zabihullah Mujahid said the Islamic State or groups affiliated with it may have carried out the explosion. He also said an investigation was under way and that Taliban security forces were working to identify and arrest those responsible. The statement presented Islamic State involvement as a possibility, not as a confirmed attribution.

Mohammad Mohaqeq, leader of the Islamic Unity Party of the People of Afghanistan, condemned the blast and called for an independent investigation. Reporting on his reaction also said he placed responsibility on the Taliban as the de facto authorities controlling security—an allegation, not an established finding.

Why Dasht-e-Barchi matters

Dasht-e-Barchi is a predominantly Hazara and Shiite area of western Kabul that has repeatedly experienced violence against religious and ethnic minorities. Human Rights Watch has documented repeated Islamic State-Khorasan Province, or ISKP, attacks against Hazaras and other religious minorities at schools, mosques and workplaces.

The neighborhood’s history includes the 2021 bombing near Sayed ul-Shuhada girls’ school and the 2022 bombing at Abdul Rahim Shahid High School. Those earlier attacks are part of the context behind concerns about a possible ISKP motive, but they do not establish that ISKP carried out the Sham-e-Hedayat blast.

UN calls for an independent investigation

Richard Bennett, the UN special rapporteur on human rights in Afghanistan, condemned what he described as a heinous attack harming children and said a full, independent investigation was essential to bring those responsible to justice.

The UN Assistance Mission in Afghanistan likewise called for an investigation into the circumstances of the explosion. The calls reflect the central evidentiary gap: the grenade has been identified, but there is no publicly verified account of who threw it, whether the school was deliberately targeted or whether any group directed the attack.

The timing after the Taliban takeover anniversary

The explosion came on 17 August, shortly after the fifth anniversary of the Taliban’s return to power in Kabul on 15 August 2021. Protests marking that anniversary were reported in several cities abroad amid criticism of Taliban human-rights policies.

That timing is relevant political context, but it is not evidence that the anniversary, the protests or any associated actor caused or directed the school explosion.

What remains unknown

The available evidence supports the conclusion that a grenade exploded at the school and that at least 42 children were injured. It does not yet establish:

• who threw the grenade;
• whether the device was thrown from the opposite alley as reported by a health source;
• whether the school, its students or the Hazara-Shiite community was deliberately targeted;
• whether ISKP or another group was involved; or
• whether the Taliban investigation will produce independently verifiable findings.

Until those questions are answered, the responsible account is a confirmed grenade blast with severe child casualties—but no confirmed perpetrator or motive.
