A preliminary military investigation has found that outdated targeting data may have led to a mistaken U.S. missile strike on a school in Iran, according to officials familiar with the ongoing inquiry.

The findings contradict earlier assertions by President Trump that Iran could be responsible for the incident. The investigation is examining how intelligence failures and outdated information may have contributed to the targeting error.

The strike occurred amid heightened tensions between the United States and Iran, though specific details about casualties and the exact timing of the incident have not been disclosed by military officials.

Military investigators are focusing on the intelligence gathering and target verification processes that preceded the strike. The preliminary nature of the findings suggests the investigation remains active, with officials continuing to examine the circumstances that led to the school being targeted.

The incident raises questions about military targeting procedures and the reliability of intelligence data used in strike decisions. Officials have not indicated when the full investigation might be completed or what changes to targeting protocols might result from the findings.
