US says commercial vessels continue to pass through open Strait of Hormuz

Iran’s Islamic Revolutionary Guard Corps (IRGC) Navy announced on Saturday that it had closed the Strait of Hormuz to all maritime traffic, citing what it described as US violations of ceasefire commitments and Israeli attacks in Lebanon.

Fars News Agency quoted a military source in the IRGC Navy as saying the strategic waterway had been “completely closed” as of Saturday morning.

In a subsequent statement, the IRGC Navy said the move was a response to “US breaches of commitments in implementing the ceasefire” and “Israeli attacks in Lebanon.”

The force warned all vessels against approaching the Strait of Hormuz, saying their security could be endangered if they ignored the warning.

US Vice President JD Vance said on Saturday he expected to travel to Switzerland within days for talks with Iran and that the negotiations could take place as soon as Sunday.

Vance, speaking to Fox News, said US special envoy Steve Witkoff and Jared Kushner were already on the ground for the talks. He said discussions with Iran were going well and that the United States would give negotiations a chance.

Vance said he was confident the ceasefire could hold. He also said there was no evidence Iran was closing the Strait of Hormuz, after Iranian military authorities said they would close it to vessel traffic.

"I expect that I will leave sometime in the next couple of days, but you know it's always a delicate coordination dance," Vance said.

Iran's Khatam al-Anbiya Central Headquarters said on Saturday it would close the Strait of Hormuz to vessel traffic, citing what it called US failure to implement the first clause of an agreement to end the war.

It also cited what it called Israel's continued breaches of a ceasefire in southern Lebanon and failure to withdraw from southern Lebanese territory.

The headquarters said the closure was the "first step" in Iran's response to what it called enemy breaches of commitments. It said further steps would follow if attacks continued.

US negotiators released a memorandum of understanding with Iran without waiting for its senior leadership to approve separate, still-secret proposals on how to implement the 14 points in the agreement, CNN reported, citing a source familiar with what Trump officials told top congressional lawmakers.

CNN had previously reported that US and Iranian officials were working on the proposals, including details on the future of Iran's nuclear program, citing US and regional officials.

The negotiators released the 14-point MOU in part because they did not want to delay the next phase of talks, CNN said. It said securing Iran's formal approval of the implementation proposals would have required more time.

The report also said US officials had described "gentleman's agreements" outside the written memorandum and that some senior administration officials had doubts Iran would meet commitments on its nuclear program.

US President Donald Trump said Iran had been "defeated militarily, with no Navy or Air Force," in a Truth Social post on Saturday.

"Funny how the Dumocrats like to say that Iran is in a stronger position today than they were three months ago," Trump wrote.

"That’s why I call them the Dumocrats!!!" he added.
