Trump said the US was having “very good conversations” with Iran, even as Tehran closed the strait again on Saturday.

The reversal has left diplomacy uncertain, with just three days until the US-Iranian ceasefire is due to expire.

Iran’s deputy foreign minister, Saeed Khatibzadeh, said no date had been set for the next round of negotiations, adding that a framework of understanding must be agreed first.

State television also quoted the Supreme National Security Council as saying the US had put forward new proposals after talks mediated by Pakistan in recent days.

Tehran was considering them but had not yet responded, it said.

There was no immediate sign of direct talks taking place at the weekend, despite Trump saying on Friday that negotiations would take place.

As Iran reasserts control of the Strait of Hormuz and threatens US ships, both ceasefires are tentatively holding.

Naim Qassem, the secretary general of Hezbollah, said in a message released on Saturday that the 10-day ceasefire in Lebanon was a victory for his group.

The Shia cleric, 73, said Hezbollah was “fully open to cooperation with the Lebanese authorities in a new chapter built on achieving Lebanon’s sovereignty.”

The US has said Israel and Lebanon agreed that Hezbollah should be disarmed.

India’s foreign ministry says two Indian flagged ships were targeted in the Strait of Hormuz earlier today.

In a statement published on Saturday, a spokesperson said the Iranian ambassador was summoned to meet the foreign secretary this evening.

The secretary “conveyed India’s deep concern at the shooting incident earlier today involving two Indian-flagged ships in the Strait of Hormuz”, and the ambassador was to relay the message.

Donald Trump called a meeting in the Situation Room this morning to discuss negotiations with Iran and the reopened crisis surrounding the Strait of Hormuz, according to a report.

A senior US official told Axios that unless there is a breakthrough in talks, it looks as though the war could reopen within days.

There is still no firm date for talks to resume this weekend, despite Trump’s hopes to end the conflict before the ceasefire expires on Tuesday.

An official told the outlet that today’s crisis talks were attended by senior figures of government including JD Vance, Marco Rubio, Pete Hegseth and Scott Bessent.

Iran’s parliament speaker Mohammed Bagher Ghalibaf tells Iranian state TV that any actions that interfere with Iran’s control of the Strait of Hormuz – including mine clearing – will be considered in breach of the ceasefire arrangement.

He said: “The Americans have announced a blockade in recent days; this is a reckless and misguided decision. It is impossible for others to pass through the Strait of Hormuz while we cannot.

“If the United States does not lift the blockade, transit through the Strait of Hormuz will certainly be restricted.”

The Iran Revolutionary Guards Navy says in a statement aired on Iranian state TV that the Strait of Hormuz is closed as of Saturday afternoon and will remain shut until the US blockade against Iranian vessels is lifted.

The regional commander threatens the US navy with a “hard blow” if it attacks Iranian vessels.

Any vessel ignoring warnings will be targeted, he says.

Tankers in the Gulf came under fire on Saturday as Iran reimposed its blockade of the Strait of Hormuz, just hours after declaring the vital waterway had reopened to commercial traffic.

At least two vessels reported being struck by gunfire as they tried to cross the strait, after Tehran said it would be shutting the strategic chokepoint in response to the continued US blockade on Iranian ports.

Hopes for diplomacy were dashed as Iran’s new supreme leader Mojataba Khamenei said the nation’s navy was ready to inflict “new bitter defeats” on its enemies, with the US-Iranian ceasefire set to expire within days.
