Washington, 6 April 2026 (dpa/MIA) - US President Donald Trump has again delayed his ultimatum for Iran to make a deal or face heavy attacks on its civilian infrastructure, outlining a new deadline for Tuesday evening.

In a series of interviews and an expletive-laden post on his Truth Social platform on Sunday, Trump doubled down on his threats to devastate Iran's power plants and bridges if Tehran does not end its blockade of the Strait of Hormuz.

The waterway, which is crucial to the global oil and gas trade, has been largely closed since the US and Israel launched large-scale attacks on Iran on February 28.

Trump told the Wall Street Journal that "if they don't do something by Tuesday evening, they won't have any power plants and they won't have any bridges standing."

He appeared to set out 8 pm on Tuesday (0000 GMT Wednesday) as the deadline in a post on Truth Social, after previously signalling an April 6 deadline.

Trump told US media outlet Axios that he sees a "good chance" that Iran reaches an agreement. "But if they don't make a deal, I am blowing everything up over there," he added.

In an earlier post, Trump said: "Tuesday will be Power Plant Day, and Bridge Day, all wrapped up in one, in Iran ..."

"Open the Fuckin' Strait, you crazy bastards, or you'll be living in Hell - JUST WATCH! Praise be to Allah," he continued.

In response, the speaker of the Iranian parliament, Mohammed Bagher Ghalibaf, warned Trump "won't gain anything through war crimes."

"The only real solution is respecting the rights of the Iranian people and ending this dangerous game," he added.
