Iran says it is closing the Strait of Hormuz and accuses the US and Israel of violating the ceasefire deal, after Israel continued strikes on Lebanon.
Iran's Revolutionary Guard Corps Navy says the Strait of Hormuz is closed to all vessels, citing US and Israel ceasefire violations.
The Navy issued a strict warning to all vessels: "Do not approach the Strait of Hormuz; otherwise, your security will be jeopardized."
A US Central Command spokesperson says "traffic continues to flow" in the strait, with US forces "monitoring the situation", according to several media outlets.
US Central Command (Centcom) says commercial ship traffic in the Strait of Hormuz increased today and that 55 merchant ships transited.
In a statement on X posted after the Iranian military's announcement that it is closing the strait, Centcom says: "Commercial ship traffic in the Strait of Hormuz increased June 20 as US forces continued operating in the general area to support freedom of navigation.
"Safe passage through the international waterway remained intact today as 55 merchant ships transited, moving large amounts of cargo and more than 17 million barrels of oil to global markets."
It adds: "US forces remain present and vigilant to ensure all aspects of the agreement with Iran are adhered to, obeyed, and in full force and effect."
US Vice-President JD Vance tells Fox News that the Strait of Hormuz remains fully open, after being asked about reporting in the Wall Street Journal suggesting the Iranian navy were turning away ships.
"We’re not seeing any evidence that the Iranians are still closing down the Strait of Hormuz," Vance says.
"We actually got 16 million barrels of oil out of the Strait of Hormuz yesterday," Vance says. "So you’re seeing those ships move."
It comes as Israel and Hezbollah have both accused each other of violating a new ceasefire. The conflict raises questions about the future of a permanent US-Iran deal.
Pakistan's foreign ministry says talks will be held in Bürgenstock in Switzerland on 21 June, attended by US and Iranian representatives.
Mediators from Pakistan and Qatar will also attend, with Pakistan facilitating the process as mediator, according to a statement on X posted after the announcement from the Iranian military that it is closing the Strait of Hormuz.
The aim of the talks is "advancing the understandings reached" in the 14-point memorandum of understanding, it adds.
It comes after talks in Switzerland - due to be attended by Vice-President JD Vance - were postponed earlier this week, with the White House saying the logistics had not been "simple or predictable".
Hours before the White House issued its statement, Hezbollah-linked Lebanese media reported that the talks had been suspended due to Israeli air strikes in Lebanon.
The deal between Iran and the United States was always fragile and torturous in the making.
Already there are signs it is unravelling.
The partial reopening of the Strait of Hormuz, through which 20% of the world’s oil passes, was the principal achievement of the Memorandum of Understanding and a key priority for the United States seeking to avoid a global economic crisis.
Now after just a few days, the Iranian military says it’s closed again, with Iran citing "relentless and continuous" breaches of the ceasefire in Lebanon by Israel which continues to occupy a large chunk of the south of the country.
All eyes will now be on President Trump to see what pressure can be applied to its ally, Israel to force it to rein in its military operation in Lebanon.
It comes after a week of unprecedented criticism of Israel by the White House over its actions in Southern Lebanon, accusing the Israeli military of using excessive force.
