The B1 bridge, which connects the city of Karaj to the capital, Tehran, was struck twice, with a section still under construction. Iranian Foreign Minister Araghtchi condemned the attacks on civilian structures, asserting they would not compel Iran to capitulate. In a statement on Truth Social, US President Trump warned of further infrastructure destruction, including bridges and power plants, if Iran does not engage in negotiations. US military sources indicated that the bridge’s destruction would hinder Iran’s ability to distribute components for ballistic missiles and drones.
