U.N. Fact-Finding Team Opens Probe into Deadly Strike on Iranian Primary School

Inquiry underway after two missile strikes killed 168 children as U.S. military investigation remains incomplete

By Avery Klein

A United Nations fact-finding mission has begun examining a lethal assault on the Shajareh Tayyebeh primary school that Iranian officials say killed 168 children, mostly girls. The strike occurred on the first day of U.S.-Israeli attacks on Iran. U.S. military investigators previously indicated it was likely that U.S. forces were responsible, but they have not reached a final conclusion; the Pentagon has elevated its probe.

U.N. Fact-Finding Team Opens Probe into Deadly Strike on Iranian Primary School

Key Points

  • A U.N. fact-finding mission has opened an investigation into a strike on Shajareh Tayyebeh School that Iranian officials say killed 168 children, mostly girls.
  • U.S. military investigators had earlier reported it was likely U.S. forces were responsible but had not completed a final conclusion; the Pentagon has elevated its probe.
  • The U.N. mission described its work as being at an early stage and said it had received credible reports supporting Iran's reported death toll.

A U.N. investigation has been launched into a deadly attack on a primary school in Iran that Iranian officials say occurred on the first day of U.S.-Israeli military action against the country, a member of the mission told reporters on Tuesday.

Iranian authorities in Geneva described the assault on the Shajareh Tayyebeh School as two missile strikes fired in rapid succession, reporting the deaths of 168 children, the majority of whom were girls.

Earlier reporting on March 5 indicated that U.S. military investigators believed it likely that U.S. forces were responsible for the strike, though those investigators had not reached a final determination and their work remained unfinished. The Pentagon has since elevated that probe.

Max du Plessis, a member of the U.N. Fact-Finding Mission on Iran, said at a Geneva press conference: "We’re at an early stage of that investigation," and added that the mission had received credible reports supporting the death toll provided by Iranian officials.

He emphasized the need for an independent inquiry given the scale of civilian loss. "It’s clear to us that whatever happens in respect of such an event, given the innocent lives that have been lost, there is a critical need for such an investigation to be done and for an independent outcome to follow," he said.

If an investigation were to confirm U.S. responsibility, the incident would rank among the most severe episodes of civilian fatalities in several decades of U.S. military strikes in the Middle East, according to observers cited in the reporting.


Context and procedural status

The U.N. mission has only recently begun its work on this case and has described its current phase as preliminary. At the same time, U.S. military investigators had earlier reported a likelihood of U.S. involvement but had not completed a final assessment.

The Pentagon has elevated the domestic probe, signaling a heightened level of scrutiny while both the U.N. inquiry and the U.S. military investigation proceed.

Given the early stage of the U.N. fact-finding mission, details remain limited and the outcomes of both investigative tracks have yet to be determined.

Risks

  • Uncertainty over investigative conclusions - both the U.N. inquiry and the U.S. military probe are incomplete, leaving the responsible party unconfirmed; this creates political and diplomatic risk for governments involved, which could affect defense contractors and geopolitical-sensitive markets.
  • Potential reputational and strategic fallout - if U.S. fault were confirmed, the incident could rank among the most severe civilian casualty events in recent U.S. military operations in the Middle East, introducing heightened geopolitical tensions that may influence defense and regional security-related economic sectors.
