JUST IN: New Footage Emerges Showing Moment of U.S.-Israeli Airstrike on Iran’s B1 Bridge in Karaj
Dramatic new video footage has surfaced capturing the moment a major U.S.-Israeli airstrike hit the B1 suspension bridge near Karaj, west of Tehran, severely damaging the structure and reportedly cutting it in half. Iranian officials say the attack killed at least eight civilians and injured up to 95 others, with some reports indicating the death toll may have risen to 13.

The B1 bridge — one of Iran’s tallest and most ambitious infrastructure projects, intended as a key link between Tehran and Karaj (and ultimately toward the Caspian Sea region) — was struck in at least two waves. Footage circulating on social media and shared by international outlets shows large explosions engulfing sections of the bridge, followed by thick plumes of smoke and the dramatic collapse of the roadway deck. President Donald Trump publicly claimed responsibility, posting video of the strike and stating: “The biggest bridge in Iran comes tumbling down, never to be used again — Much more to follow!”
Iranian state media described the casualties as civilians, including families picnicking nearby during the Nowruz holiday period (Nature Day celebrations). The bridge was reportedly still under construction or recently nearing completion at the time of the attack.
Details of the Strike and Damage
- The bridge, a high suspension structure, sustained catastrophic damage to its central span, with sections visibly severed.
- Reports indicate a “double-tap” pattern: an initial strike followed by a second wave targeting responders or the damaged area.
- Iranian officials condemned the targeting of civilian infrastructure as a “moral collapse” and vowed retaliation, with some threats mentioning bridges in Israel or the Gulf.
This incident fits into a broader pattern of U.S.-Israeli strikes on Iranian infrastructure amid the ongoing conflict, which has already seen significant U.S. aircraft losses (including multiple F-15Es, an A-10, AWACS, tankers, and numerous MQ-9 drones).
Broader Conflict Context
The Karaj bridge strike occurs as:
- Iran continues asymmetric responses, including recent barrages of ballistic missiles and drones toward the UAE, and a claimed attack on an Israeli-linked ship at Bahrain’s Khalifa Port.
- The Strait of Hormuz remains heavily disrupted, with selective commercial transits but no full reopening expected soon.
- Diplomatic signals remain mixed: Iran’s Parliament Speaker has expressed openness to talks with Gulf countries, while former FM Zarif urges declaring victory and negotiating.
- Ukrainian President Zelensky is in Istanbul today meeting Turkish President Erdogan, amid Turkey’s mediation role across multiple crises.
Reflecto News will continue monitoring verified casualty figures, official statements from Washington and Tehran, any Iranian retaliation, and the humanitarian and logistical impact of the damaged bridge on the Tehran-Karaj corridor.
