US President Donald Trump says Iran could be “taken out” in one night as the deadline set for the country to open the Strait of Hormuz to shipping traffic approaches.

On Saturday, Trump gave Iran 48 hours to comply or risk facing “hell”.

He later threatened that the US would blow up Iran’s power plants and bridges if Tehran failed to adhere to his warning.

The US president said Iran had until Tuesday at 8 p.m. ET (1 am WAT) to make a deal.

In a press conference on Monday, Trump reiterated and intensified his threats.

“The entire country could be taken out in one night, and that night might be tomorrow night,” he said.

“We have a plan, because of the power of our military, where every bridge in Iran will be decimated by 12 o’clock tomorrow night, where every power plant in Iran will be out of business – burning, exploding and never to be used again, I mean complete demolition – by 12 o’clock.

“And it’ll happen over a period of four hours if we want it to. We don’t want that to happen.”

Meanwhile, Iran has reportedly rejected a ceasefire proposal and has insisted for a permanent end to the war.
