Trump’s post on social media came shortly after the U.S. military seized another tanker associated with the smuggling of Iranian oil, ratcheting up a standoff with Tehran over the strait through which 20% of all crude oil and natural gas traded passes.
“I have ordered the United States Navy to shoot and kill any boat, small boats though they may be...that is putting mines in the waters of the Strait of Hormuz,” Trump posted. “There is to be no hesitation. Additionally, our mine ‘sweepers’ are clearing the Strait right now.”
“I am hereby ordering that activity to continue, but at a tripled up level!” Trump added.
He also said the military is intensifying mine clearing operations in the critical waterway.
The move comes a day after Iran’s paramilitary Revolutionary Guards attacked three cargo ships in the strait, capturing two of them.
The Defense Department released video footage earlier on Thursday of U.S. forces on the deck of the Guinea-flagged oil tanker Majestic X, which was seized in the Indian Ocean.
“We will continue global maritime enforcement to disrupt illicit networks and interdict vessels providing material support to Iran, wherever they operate,” a Pentagon statement said.
Ship-tracking data showed the Majestic X in the Indian Ocean between Sri Lanka and Indonesia, roughly the same location as the oil tanker Tifani, earlier seized by American forces. It had been bound for Zhoushan, China.
The vessel previously had been named Phonix and had been sanctioned by the U.S. Treasury Department in 2024 for smuggling Iranian crude oil in contravention of U.S. sanctions on the Islamic Republic.
There was no immediate response from Iran on the news of the seizure.
