US military investigators believe it is likely that US forces were responsible for an apparent strike on an Iranian girls’ school that killed scores of children on Saturday, but have not yet reached a final conclusion or completed their investigation, two US officials tell Reuters.

Reuters is unable to determine more details about the investigation, including what evidence contributed to the tentative assessment, what type of munition was used, who was responsible, or why the US might have struck the school.

US Defense Secretary Pete Hegseth on Wednesday acknowledged the US military was investigating the incident.

The officials, who spoke on condition of anonymity to discuss sensitive military matters, do not rule out the possibility that new evidence could emerge that absolves the US of responsibility and points to another responsible party in the incident.

Reuters cannot determine how much longer the investigation will last or what evidence US investigators are seeking before the assessment can be completed.

The girls’ school in Minab, in southern Iran, was hit on Saturday during the first day of US and Israeli attacks on the country. Iran’s ambassador to the US in Geneva, Ali Bahreini, said the strike killed 150 students. Reuters cannot independently confirm the death toll.

According to archived copies of the school’s official website, the school is adjacent to a compound operated by the Islamic Revolutionary Guard Corps (IRGC), the military force that reports to Iran’s supreme leader.

The Pentagon referred questions from Reuters to the US military’s Central Command, whose spokesperson, Captain Timothy Hawkins, says: “It would be inappropriate to comment given the incident is under investigation.”
