On Sunday, the US military announced a "blockade" of Iranian ports to begin at 14:00 GMT on Monday. It said it would be "enforced impartially against vessels of all nations entering or departing Iranian ports and coastal areas".

But yesterday, ship tracking data analysed by BBC Verify showed that at least four Iran-linked ships crossed the Strait of Hormuz as the US blockade of Iranian ports began.

Later, the US Central Command (Centcom) insisted no ships had made it past its blockade - saying six merchant vessels "complied with direction from US forces" to turn around and "re-enter an Iranian port".

A US official told the BBC's US partner CBS that the US had interdicted two oil tankers on Tuesday, which were part of the six told to turn back by US forces.

Tracking data shows that one Iran-linked vessel, the Rich Starry, did indeed cross the strait, heading east. But it then seems to turn back upon reaching the Gulf of Oman - possibly under the instruction of US forces.

BBC Verify reported yesterday that at least one other vessel, the Christianna - which crossed the strait having called at Iran’s Bandar Iman Khomein - also changed direction.

Talks between the US and Iran could restart "in the next two days", Donald Trump has said, in an interview with the New York Post., external

The paper said that, in an initial phone interview, the US president said discussions were "happening, but, you know, a little bit slow" - before indicating more talks could happen in Europe.

About half an hour later, the paper says, Trump called their reporter back.

"You should stay there [Islamabad, where talks previously happened], really, because something could be happening over the next two days, and we’re more inclined to go there," he said.

"It’s more likely, you know why? Because the field marshal is doing a great job."

Trump was referring to Pakistan Field Marshal Gen Asim Munir - who he has previously called his "favourite".

The efficacy of the US naval blockade of Iranian ports has remained largely unclear during its first full day, with our security correspondent Frank Gardner suggesting a lack of preparation and transponder interference as possible explanations.

Shipping data analysed by BBC Verify shows that at least four Iran-linked ships, including two that visited Iranian ports, crossed the Strait of Hormuz on Tuesday.

A further three ships that were not linked to Iran were seen to have crossed the strait after the blockade started at 10:00 ET (14:00 GMT) on Monday.

On Tuesday, Adm Brad Cooper, the commander of US Central Command said: "A blockade of Iranian ports has been fully implemented."

"In less than 36 hours since the blockade was implemented, US forces have completely halted economic trade going into and out of Iran by sea," he added.

US Central Command earlier said that six merchant vessels turned around and re-entered an Iranian port after complying with "direction from US forces" - while ship tracking data analysed by BBC Verify showed two Iran-linked ships changing direction after travelling through the strait off the back of the blockade being imposed.

Oil prices were steady in Asia trade today as hopes of new US-Iran peace talks grow.

Donald Trump has suggested that talks could restart "in the next two days", though Tehran has said there is "no information" about any agreement for a second meeting.

The price of global benchmark Brent crude gained by 0.3% just above $95 (£70) a barrel, while US-traded oil was lower by 0.3% at just shy of $91.

Energy prices came down on Tuesday after Trump said that the White House was contacted by Iran in hopes of making a deal.

Major Asian markets also gained on Wednesday. The Nikkei 225 index in Japan was up by around 1%, while South Korea's Kospi exchange rose by 3%.

US President Donald Trump says the war with Iran is "close to over" during an interview with Maria Bartiromo on Fox.

In a preview clip of the interview posted to Fox News online, Trump is ask directly whether the war has ended.

"I think it's close to over, yeah," he replies. "I view it as very close to over."

The full interview is set to air at 06:00 ET (11:00 BST) on the Fox Business Network.

The first 24 hours of the US naval blockade of Iran's ports have been notable for their inconsistency.

At least four Iran-linked vessels have passed through the narrow Strait of Hormuz, two of them having come from Iranian ports: Bushehr and Bandar Imam Khomeini.

There are several possible explanations for this.

One is that US naval forces were not quite ready to enforce it yet. Another suggestion is that the vessels interfered with their onboard AIS transponders to mislead others as to their true whereabouts, a practice known as "spoofing".

Then there is the China factor. China is a major buyer of Iran's oil and it has made no secret of its displeasure over the restrictions on energy supplies coming out of the Gulf, calling the blockade reckless and dangerous.

China would prefer to resolve this crisis by peaceful, diplomatic means. But as the standoff continues there may well be discussions back in Beijing about whether it is now time to consider providing a naval escort for cargoes bound for China.

During an event on Tuesday, US Vice-President JD Vance said Trump wanted to make a "grand bargain" with Iran, BBC's US partner CBS News, reports.

Vance told the audience at a Turning Point USA event in Athens, Georgia, that negotiators "made a ton of progress" in Pakistan over the weekend.

But he said Trump is not looking for a "small deal" with Iran, and instead wants to strike a "Trumpian grand bargain", CBS says.

Vance noted there was a lot of mistrust between the two countries.

"You are not going to solve that problem overnight," he said, according to Reuters.

Donald Trump has hinted that a second round of talks with Iran could take place later this week.

It follows the collapse of negotiations in Pakistan last weekend, with Washington and Tehran failing to reach an agreement over the Strait of Hormuz and the future of Iran's nuclear programme.

US Vice-President JD Vance acknowledged that mistrust between the two countries, spanning several decades, could not be overcome overnight, but he believed the Iranian negotiators wanted to make a deal.

He reiterated that it was the Trump's policy that Iran could not have a nuclear weapon and that negotiations to that end were taking place.

Speaking to the New York Post yesterday, Trump said peace talks "could be happening over the next two days".
