U.S. President Donald Trump stated on Wednesday it may never be determined who carried out the February 28 airstrike on a girls’ school in Minab, Iran, which killed more than 175 children and teachers on the opening day of the Iran war.

Speaking to reporters, Trump cast doubt on the prospect of establishing accountability. “I don’t know that they are ever going to solve that problem in terms of whose fault was it because there were missiles flying all over the place,” he said. He added that he had seen no evidence pointing to U.S. involvement, stating, “I don’t think it was us.”

Reuters reported in March that an initial internal Pentagon investigation indicated U.S. forces were likely responsible for the deadly strike. Sources cited by the news agency suggested the attack may have resulted from the use of outdated targeting data. The Pentagon has since elevated the probe but has not publicly acknowledged any preliminary findings or accepted responsibility. Under international humanitarian law, deliberately striking a school constitutes a war crime.

The attack triggered widespread international condemnation, with the United Nations human rights office describing the incident as “absolutely horrific.” Trump initially suggested, without providing evidence, that Iran bore responsibility, but later walked back that claim, maintaining that nobody purposefully attacked the school.
