US military strikes Karaj B1 Bridge twice — second hit while rescuers on scene, 2 killed

·Karaj, Iran

US forces struck the B1 bridge on the Karaj northern bypass west of Tehran on April 2, twice in quick succession. Iranian state media reported the death toll rose to 13 (up from the initial report of 8). The bridge was still under construction at the time. Iran's FM condemned the strike as targeting civilian infrastructure and a potential war crime.

The US military struck the B1 Bridge in Karaj (Tehran-Karaj highway) twice on April 2 (D34). The IDF specifically denied striking the bridge, confirming it was a US operation. Strike 1: - Killed 2 people (per Fars News Agency) - Several others injured Strike 2: - Struck while 'rescue forces were assisting the victims of the first attack' (Fars) - Timing: approximately 17:30 local time (second strike per video timestamp) Attribution: IDF statement: 'IDF denies striking the bridge' — confirms US military carried it. The B1 Bridge is the Middle East's highest bridge, inaugurated earlier in 2026, on the main Tehran-Karaj highway (Iran's 3rd-largest city, ~2 million). Targeting it twice in one day — and hitting it while rescue workers were on scene — escalates the tactical pattern beyond standard infrastructure targeting. Note: Striking an area known to have civilian rescue workers present raises questions under international humanitarian law and may be cited by Iran and international bodies as a war crime.
