New evidence compiled by CNN suggests the United States military was responsible for a devastating strike on an elementary school in southern Iran that killed scores of children. This attack represents the deadliest incident of civilian casualties in the ongoing conflict between the US, Israel, and Iran, which has now lasted nearly a week.

CNN's investigation, reported by Isobel Yeung, provides compelling imagery and analysis pointing to American involvement in the strike. The bombing occurred amid escalating tensions and military operations in the region, where cross-border bombardments and drone attacks have become increasingly common. Iranian communications have been severely disrupted, making independent verification challenging.

The school bombing has intensified international scrutiny of military operations in the region. As Iranian hardliners gather in Tehran to mourn the death of the Supreme Leader, the civilian death toll continues to rise. The incident raises serious questions about military targeting protocols and the protection of civilian infrastructure during armed conflicts.
