Six Democratic U.S. Senators have expressed shock over an airstrike on an Iranian girls' school on February 28, which independent analysis suggests may have been conducted by the U.S. military. According to Jin10, the senators issued a joint statement calling for a comprehensive and impartial investigation into the incident, which could be one of the most severe cases of civilian casualties caused by U.S. military actions in the Middle East in decades if confirmed. They urged U.S. Defense Secretary Pete Hegseth to explain to the public and Congress how and why the attack occurred. The U.S. Department of Defense has announced an ongoing investigation into the matter. Meanwhile, U.S. President Donald Trump has attributed the attack to Iran, although U.S. media and some experts suggest a higher likelihood of U.S. military involvement.
