Amid the intensifying conflict in Iran, a particularly devastating incident was reported on February 28 in the city of Minab, where a U.S. military strike allegedly hit the Shajareh Tayyebeh school, resulting in the deaths of more than 168 civilians, most of them young girls. The scale of the tragedy has made it one of the deadliest single attacks attributed to U.S. operations in recent decades, with initial internal military assessments reportedly acknowledging U.S. responsibility. The incident has since become emblematic of the broader civilian toll arising from ongoing U.S. and Israeli military actions within Iranian territory, raising urgent concerns about compliance with international humanitarian norms.
The magnitude of civilian casualties has triggered widespread calls for accountability. Members of the U.S. Congress, along with multiple human rights organizations, have demanded a formal and transparent investigation into the strike, including an assessment of whether it constitutes a war crime. In response, the U.S. Department of Defense has initiated an administrative inquiry through a designated investigating officer under the framework commonly referred to as an “AR 15-6” investigation. Parallelly, international scrutiny has intensified, with the United Nations Fact-Finding Mission on Iran prioritizing the case and indicating that the reported casualty figures appear credible at this stage.
This investigation is not occurring in isolation but forms part of a broader pattern of inquiries into civilian harm linked to U.S. military operations across various regions. Past studies examining such investigations, including extensive reviews of similar cases, have highlighted recurring gaps in transparency, accountability, and procedural rigor. These findings underscore the critical need for credible and thorough investigations, not only to establish legal responsibility but also to ensure redress for victims, prevent future harm, and maintain military discipline and public trust.
Under international humanitarian law, states are obligated to investigate incidents involving potential violations, particularly where there is evidence of large-scale civilian harm. War crimes, as defined under the Rome Statute of the International Criminal Court and rooted in the 1949 Geneva Conventions, encompass serious breaches such as willful killing of civilians, disproportionate attacks, and failure to take necessary precautions to minimize harm. Central to this legal framework are the principles of distinction, proportionality, and precaution, which require that parties to a conflict differentiate between civilian and military targets, avoid excessive force relative to anticipated military advantage, and take all feasible measures to protect civilian life.
However, the realities of modern warfare often blur the line between civilian and military spaces, complicating the application of these principles. While not every civilian casualty automatically constitutes a war crime, attacks that result in excessive, avoidable, or unjustified harm may cross that threshold. The Minab school strike, given its scale and the nature of the target, raises serious legal and moral questions in this regard. Furthermore, it highlights the broader challenge of distinguishing between lawful military conduct and actions that may amount to violations of international law.
The distinction between war crimes and crimes against humanity also remains significant in this context. While war crimes are tied specifically to conduct during armed conflict, crimes against humanity can occur even outside war and involve widespread or systematic attacks against civilian populations. As investigations proceed, the findings will be crucial in determining not only the legality of the strike but also the extent of accountability required under international law.
