President Donald Trump on Thursday issued a fresh warning to Iran, urging Tehran to strike a deal "before it is too late," even as US strikes targeted key infrastructure, and major bridge near the capital.Posting on Truth Social, Trump shared a video of Karaj bridge being hit in Iran. "The biggest bridge in Iran comes tumbling down, never to be used again, Much more to follow!" he wrote.

He added a direct warning to Tehran saying, "It is time for Iran to make a deal before it is too late, and there is nothing left of what still could become a great country!"The remarks came after US strikes reportedly hit a major highway bridge connecting Tehran to Karaj.

Iranian media described it as one of the highest bridges in the Middle East.

The structure, identified as the B1 bridge in Karaj, was still under construction and was part of a key highway project linking the region to the capital. The 136-metre-high bridge was partially destroyed in the attack, according to Iranian state media.Several people were reported injured in the strike, which Tehran said was carried out by the United States and Israel.

Iranian authorities also claimed that a historic medical facility in Tehran was struck. Images released by the health ministry showed significant damage to a building identified as the Pasteur Institute of Iran, a century-old research centre.The latest strikes come amid intensifying hostilities in the region, with Washington stepping up pressure on Tehran while continuing military operations. Trump’s warning signals a hardening stance, as the US pushes for a deal even as the conflict widens on the ground.
