WASHINGTON — U.S. forces struck a major bridge in Iran on Thursday, partially destroying the structure in an operation aimed at disrupting Iranian military supply lines amid the ongoing conflict with Iran and Israel.
The strike targeted the B1 bridge, also known as the Bileghan Bridge, which connects Tehran to the city of Karaj in Alborz province west of the capital. Iranian state media and local officials reported that the attack killed eight people and wounded 95 others.
A U.S. military official confirmed that American forces carried out the strike, describing the bridge as a planned route for moving missiles and drone components to launch sites in western Iran. The official spoke on condition of anonymity.
Iranian Deputy Governor of Alborz province Ghodratollah Seif said the casualties occurred among people near the bridge, according to state media reports. Details on the exact circumstances of the deaths and injuries remained unclear, with some accounts indicating the bridge was under construction or recently completed.
U.S. President Donald Trump posted on social media celebrating the strike, sharing video footage and writing that “the biggest bridge in Iran comes tumbling down, never to be used again — Much more to follow!” Trump also warned Iran to “make a deal before it’s too late.”
The strike occurred as part of broader U.S. and Israeli military operations against Iran that began on Feb. 28. U.S. officials have said the campaign targets Iranian missile and nuclear capabilities as well as leadership and military infrastructure. Iran has responded with missile and drone attacks on U.S. and Israeli positions and regional allies.
Iranian officials have described the bridge as a key civilian transportation link and one of the tallest in the region. They did not immediately comment on its military significance but condemned the strike as targeting infrastructure.
A U.S. defense official told reporters that the operation sought to prevent the transfer of weapons across the bridge. Details on the method of the strike, including the type of munitions used, were not disclosed by U.S. authorities.
The conflict has escalated since late February, with both sides reporting strikes on military and, in some cases, civilian sites. Casualty figures from the wider fighting have varied widely depending on the source, and independent verification has been limited.
As of Thursday evening, there were no immediate reports of further U.S. or Iranian strikes directly linked to the bridge attack. Iranian state media said rescue operations were underway at the site, while U.S. officials provided no additional updates on the operation’s outcome.
The Pentagon did not immediately respond to requests for comment on the strike’s impact on Iranian military movements. Iranian authorities have vowed to continue resistance against what they call aggression by the United States and Israel.
