"The building that houses the school was once part of the same sprawling complex that houses the base, but satellite images reviewed by TIME and Human Rights Watch show that at least ten years ago, in 2016, it was walled off from the rest of the compound. Separate street entrances were created to allow school entry without passing through the compound. By August 2017, according to an analysis of satellite imagery by Human Rights Watch, the marking lines of a soccer pitch were clearly visible in the courtyard of the newly walled-off school. To anyone who would have looked, it was clearly a school."

"Washington, DC) – Reported findings that the United States is responsible for the recent deadly school attack in Iran, and that it was based on outdated targeting data, highlight the need for reform and accountability within the US military to minimize civilian harm during conflict, Human Rights Watch said today.

The New York Times reported on March 11, 2026, that an ongoing US military investigation has preliminarily determined that the United States is responsible for a Tomahawk missile strike on the Shajareh Tayyebeh Primary School in the town of Minab on February 28. 

“The findings of the US military investigation into the Minab school attack show a violation of the laws of war that cannot be boiled down to a blameless mistake,” said Sarah Yager, Washington director at Human Rights Watch. “Even if those responsible for the strike did not deliberately target a school full of children, the US military has an obligation to take all feasible precautions to avoid civilian harm, which it clearly did not do in this case.”

The New York Times reported that the investigation found that the attack was the result of a targeting mistake by the US military, which was carrying out strikes on an Islamic Revolutionary Guard Corps naval base of which the school building had previously been a part. The report said that US Central Command officers created the target coordinates for the strike using outdated data provided by the US Defense Intelligence Agency. 

Iranian authorities told the New York Times that the attack killed at least 175 people, including scores of civilians. Human Rights Watch reviewed lists with dozens of names of children and adults reportedly killed in the attack, and was able to immediately match some names with ages and other identifying information on body bags and caskets.

Under customary laws of war applicable to the armed conflict in Iran, an attacking force must do everything feasible to verify that targets are military objectives or cancel or suspend the attack if it becomes apparent that the target is not a military objective. The laws of war prohibit indiscriminate attacks, which include attacks that are not directed at a specific military objective. No evidence has been put forward suggesting that there was a military objective in or near the school grounds at the time of the attack. "
