Story summary

On February 28, a UN-backed report found reasonable grounds to conclude that the US committed war crimes in Iran, focusing on two airstrikes: one hit Shajareh Tayyebeh Primary School in Minab, killing over 150 civilians, including approximately 120 children; another strike hit a sports complex and residential area in Lamerd, reportedly killing 22 people. The report also accused Iranian authorities of human rights violations during the country’s protests. In response, the White House dismissed the UN Human Rights Council's findings as "unserious nonsense," asserting that Iran is responsible for war crimes and terrorizing the world by seeking nuclear weapons.
