The Strait of Hormuz remains open to all shipping except vessels linked to "Iran's ‌enemies", Iran's representative to the UN maritime agency said on Sunday, after US President Donald Trump threatened to target Iranian power plants if the waterway was not "fully open" within ⁠48 hours.

The threat of Iranian attacks during the US-Israeli war on Iran has kept most ships from getting through the narrow strait, the conduit for around a fifth of global oil and liquefied natural gas supplies, threatening a global energy shock.

Ali Mousavi said Tehran was ready to ‌cooperate ⁠with the International Maritime Organisation to improve maritime safety and protect seafarers in the Gulf, adding that ships not linked to "Iran's enemies" could pass the strait ⁠by coordinating security and safety arrangements with Tehran.

"Diplomacy remains Iran's priority. However, a complete cessation of aggression as ⁠well as mutual trust and confidence are more important," Mousavi said, adding that Israeli and ⁠US attacks against Iran were at the "root of the current situation in the Strait of Hormuz".

Earlier, Trump had threatened to "obliterate" Iran's power plants if Tehran did not fully reopen the Strait of Hormuz within 48 hours, a significant escalation barely a day after he talked about "winding down" the war.

"If Iran doesn't FULLY OPEN, WITHOUT THREAT, the Strait of Hormuz, within 48 HOURS from ‌this exact point in time, the United States of America will hit and obliterate their various POWER PLANTS, STARTING WITH THE BIGGEST ONE FIRST!" Trump said on social media.

Trump's ultimatum would expand the scope of US strikes to infrastructure that affects daily civilian life in Iran.

The threat of Iranian attacks has kept most ships from getting through the strait, a narrow waterway that serves as the conduit for around a fifth of global oil and liquefied natural gas supplies, threatening a global energy shock. Its near-closure sent European gas prices surging as much as 35% last week.
