DUBAI, United Arab Emirates (AP) — President Donald Trump has ordered the U.S. military to “shoot and kill” small Iranian boats that deploy mines in the Strait of Hormuz, he said Thursday, a day after Iran again displayed its ability to thwart traffic through the channel.

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, adding that U.S. minesweepers “are clearing the Strait right now.”

“I am hereby ordering that activity to continue, but at a tripled up level!” he added.

Meanwhile, it was still unclear when, or if, the two sides would meet again in the Pakistani capital, Islamabad, where mediators are trying to bring the countries together to reach a diplomatic deal.

Negotiations initially planned for this week have not happened. Iran insists it will not attend until the U.S. ends its blockade on Iranian ports and ships. America insists it will not take part until Tehran opens the strait to international traffic.

Pope Leo XIV, returning home from a trip to Africa, urged the U.S. and Iran to return to talks to end the war.

The Defense Department released video footage earlier Thursday of U.S. forces on the deck of the Guinea-flagged oil tanker Majestic X, which was seized in the Indian Ocean.

The footage emerged a day after Iran’s paramilitary Revolutionary Guard attacked three cargo ships in the strait, capturing two of them, in an assault that raised new concerns about the safety of shipping through the waterway.

The powerful head of Iran’s judiciary, Gholam Hossein Mohseni Ejei, said three “violating ships” in the strait were “subject to enforcement” on Wednesday.

“The show of strength by the armed forces of Islamic Iran in the Strait of Hormuz is a source of pride,” he wrote Thursday on X, claiming that the Americans “lack the courage” to approach the strait.

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, which was seized earlier 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 against the Islamic Republic.

There was no immediate response from Iran about the seizure.Trump this week extended a ceasefire to give the battered Iranian leadership more time to come up with a “unified proposal” on ending the war, while maintaining an American blockade of Iranian ports.

In a separate post Thursday, Trump claimed a leadership rift between moderates and hardliners was confounding Iran.

“Iran is having a very hard time figuring out who their leader is! They just don’t know!” Trump said.

The president has repeatedly said over the course of the ceasefire that began on April 8 that his team is dealing with Iranian officials who want to make a deal, while acknowledging that his decision to kill several top leaders has come with complications.

Iran’s president and its parliament speaker posted almost identical statements on social media declaring that the country has no hard-liners or moderates.

“We are all Iranians and revolutionaries,” they said.

A spokesperson for the Iranian Foreign Ministry said Trump’s claim of a leadership rift was “a form of deflection.” Other Iranian officials said on social media that the country was united.

Elsewhere on the diplomatic track, Lebanon and Israel were set to hold a second round of talks in Washington to discuss the possibility of extending a truce between Israel and the Hezbollah militant group.

The latest war between Israel and Hezbollah started two days after Israel and the U.S. launched attacks on Iran, after the Tehran-backed militants fired rockets into northern Israel.

In a new show of the fragility of the ceasefire that went into effect Friday in Lebanon, Hezbollah said it attacked Israeli positions in southern Lebanon, targeting Israeli soldiers in the village of Taybeh.

Each side has accused the other of breaching the 10-day truce.
