On September 17, a UN fact-finding mission reported reasonable grounds to believe that the United States committed war crimes by striking a school and a sports facility in Iran, resulting in over 150 civilian deaths including around 120 children. The mission also found Iranian authorities guilty of crimes against humanity during their violent suppression of anti-government protests starting in December. The report will be submitted to the UN Human Rights Council but neither US nor Iranian missions responded immediately to comments from Reuters.
