US President Donald Trump said that the United States was behind the destruction of Iran’s largest bridge. He also warned that more attacks could follow.

The strike targeted a major suspension bridge located between Tehran and Karaj. The bridge stood 136 metres tall and was valued at around $400 million. The attack came just a day after Trump threatened to bomb Iran “back to the Stone Age”.

Casualties Reported After Massive Explosion

According to local authorities in Karaj and Iranian state media, at least eight people were killed in the attack. Around 95 others were injured.

Reports said the central section of the bridge was hit twice. The structure collapsed onto the road below, sending up thick black smoke. Later images showed a large gap in the middle of the bridge, which had been one of Iran’s key infrastructure projects.

Trump Issues Warning of Further Strikes

Trump spoke about the attack on his Truth Social platform. He said, “The biggest bridge in Iran comes tumbling down, never to be used again,” and warned there would be “much more to follow” if a settlement was not reached.

It remains unclear whether civilians were on the bridge at the time of the strike. However, visuals suggested that a truck was present on one side. One video circulating online showed a projectile hitting a section of the bridge that had already been damaged.

Threats to Intensify Attacks on Iran

In his first national address since the conflict began, Trump described the joint US and Israeli military actions, launched on February 28, as a success. He said the operation was “nearing completion” and claimed that the US would achieve all its strategic goals “very shortly”.

At the same time, he repeated a strong warning about targeting Iran’s energy infrastructure. “We are going to hit every one of their electric generating plants very hard and probably simultaneously,” he said. Such an attack could disrupt electricity supply for millions of people.

Strikes on Key Infrastructure Continue

Since the conflict began, the US and Israel have targeted several important infrastructure sites in Iran. There has also been discussion in the US about a possible high-risk operation to seize radioactive material stored deep underground in Iran.

However, Trump dismissed concerns about those materials, saying they were buried so deep that “I don’t care”.

Meanwhile, Iran reported that the Pasteur Institute of Iran in Tehran was hit on Thursday. This came shortly after Israel claimed it had struck a facility linked to Iran’s Revolutionary Guard, which it said was used to fund armed groups across West Asia.

Iran Promises Strong Retaliation

Iran responded strongly to the attacks. Officials said they would launch “more crushing, broader and more destructive” strikes in the future.

Ebrahim Zolfaqari, spokesperson for Iran’s military headquarters, said the conflict would continue until the “permanent regret and surrender” of Iran’s enemies.
