The Strait of Hormuz has been completely closed, forcing tankers to turn back. Iranian broadcaster Press TV reported that maritime tracking data showed that the tanker Aurora, en route to the exit of the Strait, suddenly changed course near the coast of Musandam in Oman and made a 180-degree turn, returning to the Persian Gulf.
According to several shipping sources, the Iranian navy threatened ships attempting to pass through the Strait of Hormuz without Tehran's permission with destruction, adding that transit through the waterway remains closed.
"Any ship attempting to travel at sea... will be targeted and destroyed..." the message said.
The United States called on Wednesday for Iran to open the Strait of Hormuz "immediately, quickly and safely" after reports that the strategic waterway had been closed despite a US-Iran ceasefire.
Any shutdown "is completely unacceptable," White House Press Secretary Caroline Leavitt told reporters.
"I will reiterate the president's expectation and request that the Strait of Hormuz be reopened immediately, quickly, and safely."
Leavitt also said that President Donald Trump wants to see the waterway accessible to tanker ships without any restrictions, including fees.
"The president's immediate priority is to reopen the strait without any restrictions, whether in the form of taxes or otherwise," Leavitt said.
On the other hand, US Vice President JD Vance reiterated to reporters that if Iran does not fulfill its promises to reopen the Strait of Hormuz, the ceasefire will end.
"The president is very, very clear that the deal is a ceasefire, a negotiation. That's what we deliver, and what they deliver is that the straits will reopen. If we don't see that happen, the president is not going to abide by our terms, if the Iranians are not going to abide by their terms," ??Vance told reporters outside Air Force Two as he departed Hungary.
The comments echoed statements by White House press secretary Caroline Leavitt. Vance added that the deal is in "good shape" but vowed that the Iranian regime will face serious consequences if it violates the terms of the agreement.
"Basically, we're in a good position. They're reopening the straits. We have a ceasefire. And frankly, if they violate their part of the deal, then they're going to see some serious consequences," Vance said.
