President Donald Trump announced Thursday that US forces had destroyed Iran's tallest bridge, posting footage of the structure collapsing and warning of further attacks unless Tehran agrees to end the five-week conflict. The strike on the B1 suspension bridge in Karaj, west of Tehran, is part of an intensified campaign that has also targeted steel plants and a medical research institute, according to multiple reports.

Iranian officials reported at least eight people killed and 95 wounded in the attack, though the toll could not be independently verified due to reporting restrictions. Witnesses and state media said many people were picnicking near the bridge for the Nowruz holiday when it was struck twice, with a second strike hitting as emergency teams responded. BBC reporting indicated the attack took place while many families were in the area.

Coverage comparison

Reports from multiple outlets agree that the strike took place Thursday and that Trump claimed responsibility, sharing footage on social media and stating 'The biggest bridge in Iran comes tumbling down, never to be used again - Much more to follow!' However, sources diverge on civilian casualties and the bridge's status. Iranian state media and the deputy governor of Alborz province reported eight killed and 95 wounded, while other reports cited two people killed or mentioned up to 100 injured.

The BBC also reported that the bridge was still under construction, but its footage showed people near the bridge, suggesting it was functioning as a public space during the holiday. Trump's statement called the structure a 'major bridge' and warned of 'much more to follow,' while Iran's foreign minister condemned the attack as a strike on civilian infrastructure that 'will not compel Iranians to surrender.'

The strike is part of a broader campaign over the past two weeks that has also hit steel plants, universities, and a mosque, according to verified footage and satellite imagery reviewed by journalists. BBC Verify confirmed strikes on at least two steel plants and three bridges across Iran.
