US Strike on Iran Karaj Bridge: Trump Warns of Further Attacks

The United States conducted a strike on April 2, 2026, that destroyed the B1 Bridge, one of Iran’s largest infrastructure projects, as part of a conflict that has entered its fifth week. The attack targeted the 136-metre-high suspension bridge connecting the city of Karaj to the capital, Tehran.

Iranian state media reported that eight people were killed and 95 others were wounded in the strike. The $400 million structure, which some officials described as still under construction, was split in half after being struck twice in its center.

President Donald Trump claimed responsibility for the attack on Truth Social, posting footage of the collapse and stating, The biggest bridge in Iran comes tumbling down, never to be used again. He warned that much more to follow if a settlement to end the war is not reached, adding that the United States hasn’t even started destroying what’s left in Iran.

The strike follows a primetime speech given by President Trump on April 1, 2026, in which he described the war, launched by the U.S. And Israel on February 28, as a success nearing completion. He had previously threatened to bomb the country back to the stone ages if a deal was not reached.

Strategic Objectives and Iranian Response

Reporting from i24NEWS indicates that the strike on the Karaj bridge was specifically intended to sever supply routes for drones and missiles being transported to Iranian launch units targeting U.S. And Israeli forces.

Iranian Foreign Minister Abbas Araghchi responded to the attack, stating that striking civilian structures, including unfinished bridges, will not compel Iranians to surrender.

U.S. Fighter Jet Shot Down

On April 3, 2026, U.S. Officials confirmed that a two-seat F-15 fighter jet was shot down over Iran. A search operation was initiated on Friday to locate the crew. One pilot has been rescued and is alive, while the fate of the second pilot remains unclear.

Regional Escalation and Casualties

The conflict has resulted in more than 3,000 deaths across the Middle East. According to Iran’s deputy health minister, Israeli and American strikes have killed more than 1,900 people within Iran. At least 1,300 people have been killed in Lebanon, and 19 have died in Israel.

Casualties among U.S. Personnel include 13 service members killed in action and two additional deaths resulting from noncombat causes.

Military activity has expanded across the region. Reports indicate strikes in Tehran and Karaj, as well as major explosions at a missile base in Isfahan. Qatar and Kuwait have intercepted drones, while Saudi Arabia and the United Arab Emirates reported missiles and drones entering their airspace.

Economic Impact and the Strait of Hormuz

The war has caused a significant rise in energy costs, with Brent crude futures increasing by 7.78% to $109.03 a barrel.

President Trump stated on April 3, 2026, that with more time, the U.S. can easily OPEN THE HORMUZ STRAIT, TAKE THE OIL, & MAKE A FORTUNE. The European Union is currently considering an increase in its naval force to protect shipping routes in the Strait of Hormuz that have been disrupted by the hostilities.

The United Nations Security Council is expected to vote on April 4, 2026, on a proposal that would authorize defensive actions to ensure vessels can safely transit the waterway.

Within the U.S. Government, reports from CBS News and the BBC indicate that Defense Secretary Pete Hegseth has asked Army Chief of Staff Gen Randy George to step down from his position.
