US forces struck the B1 highway bridge between Karaj and Tehran on 3 April, killing 8 civilians and injuring 95. The bridge, the Middle East's tallest at 136 metres, carried commuter traffic. CENTCOM described it as a supply line to drone and missile units.
Every prior bridge strike in this campaign targeted military or industrial corridors. A 136-metre commuter bridge between 2 major cities is a categorically different target, and the civilian casualty count will fuel the humanitarian accountability track.
