Donald Trump has given Iran 48 hours to reopen the strait of Hormuz to shipping or face the destruction of its energy infrastructure, as Tehran launched its most destructive attack yet on Israel.
The ultimatum, made just a day after the US president said he was considering “winding down” military operations after three weeks of war, came as the key oil passage remained effectively closed and thousands more US Marines headed to the Middle East.
Trump wrote on Truth Social that the US would “hit and obliterate” Iranian power plants – “starting with the biggest one first” – if Tehran did not fully reopen the strait within 48 hours, or 23:44 GMT on Monday according to the time of his post.
Tehran in response said it will “irreversibly destroy” essential infrastructure across the Middle East, including vital water systems, if the US follows through on Donald Trump’s threat.
