US, Israeli airstrikes destroy major bridge in Iran, killing eight

A strategic bridge under construction near the Iranian city of Karaj was destroyed in a dual-wave airstrike on Thursday, which U.S. and Israeli officials have confirmed as a joint military operation.

The B1 bridge, a cable-stayed structure intended to become the tallest in the Middle East, collapsed in flames after precision strikes hit the span. Iranian state media reported eight civilian deaths and several injuries.

The bridge was located on a major highway linking Tehran to western launch sites. According to a statement from U.S. officials, the structure was being used by Iran’s Islamic Revolutionary Guard Corps (IRGC) to transport missiles westward for potential strikes against Israel and American assets. The officials said the bridge was a legitimate military target.

President Trump posted video of the strike on social media, writing that the “biggest bridge in Iran comes tumbling down.” He urged Tehran to negotiate “before it’s too late” and warned of further strikes in the coming weeks if Iran does not change its course.

Iranian authorities have not confirmed the military use of the bridge. A spokesperson for the Iranian Foreign Ministry condemned the attack as an act of “state terrorism” and a violation of international law, warning that Tehran reserves the right to respond.

The strike comes after repeated warnings from the Trump administration. In recent months, the President had called on Iran to reach a new nuclear and security deal, stating that continued defiance would lead to consequences.

Military analysts noted that closing the Strait of Hormuz, a threat Iran has made in the past, would now carry greater economic costs for Tehran as its own infrastructure comes under direct attack.

No further details on the type of aircraft or munitions used have been released. The U.S. and Israeli governments have not commented on whether additional strikes are planned.
