The US says no ships passed through its blockade in the first 24 hours, and six merchant vessels turned around after "direction from US forces" - BBC Verify analyses the latest shipping data
The first 24 hours of the US naval blockade of Iran's ports have been notable for their inconsistency, writes our security correspondent - possibly because American forces were not yet ready for it
China's foreign ministry calls the blockade "dangerous and irresponsible", while Iran calls it a violation of its sovereignty
Image source, ReutersFollowing his post (see our last post), Donald Trump has just started speaking to journalists at the White House.
You can watch it live at the top of this page - we'll write up any key lines.
President Trump has posted again on Truth Social. "34 Ships went through the Strait of Hormuz yesterday, which is by far the highest number since this foolish closure began," he writes.
The BBC has not independently verified this claim.

I'm here at the White House, where journalists in the pool have just been told to assemble.
We don't yet know what we will be covering - but stay with us for updates.
Image source, ReutersDonald Trump's criticism of Pope Leo is "unacceptable", says Italian Prime Minister Giorgia Meloni.
"I find President Trump's words toward the Holy Father unacceptable. The Pope is the head of the Catholic Church, and it is right and proper that he calls for peace and condemns all forms of war," the Italian leader says in a statement.
It comes after the US president called the Pope "terrible", not long after the pontiff had condemned the US president's threat against Iran.

Image source, Truth SocialUS President Donald Trump appears to have deleted a controversial Truth Social post depicting him as a Christ-like figure.
The picture - which showed Trump with light emitting from his hands, held over a man in a hospital bed - was criticised by notable figures from both sides of the political spectrum, including some of Trump's most ardent supporters.
The BBC has contacted the White House for comment on why the post was removed. We have so far not received any response.
The original post - which we have shared a screenshot of above - came just hours after the US president posted a lengthy missive criticising Pope Leo XIV, calling him "weak on crime" and "terrible for foreign policy".
The two men have repeatedly sparred over the war in Iran, which the Pope has strongly condemned.

During a statement to the UK Parliament earlier today, Keir Starmer said Donald Trump’s threat last week to end a “whole civilisation” unless Iran agreed to reopen the Strait of Hormuz was “wrong”.
That’s a tad stronger than the prime minister’s initial response to the remarks during an interview last Thursday, in which he said they were “not words I would use”.
Speaking in the Commons, Starmer said Iranian civilians had already suffered "immeasurable harm” at the hands of the regime over “many long years”.
Image source, ReutersReturning to Lebanon, we can now bring you a statement from the International Committee of the Red Cross (ICRC), which says it is deeply concerned by attacks on medical workers in the country.
"The loss of those who dedicate their lives to saving others is gravely concerning, given the impact on the civilians who depend on their help," says Agnes Dhur, the head of the ICRC delegation there.
Dhur's remarks, shared by the Reuters news agency, come after reports of a strike on a Lebanese Red Cross centre in southern Lebanon on Monday.
The BBC has approached the Israel Defense Forces (IDF) for comment.

Two people in the northern Israeli city of Nahariya are being treated by medics following reports of strikes being fired at the city, according to Israel's Magen David Adom emergency service.
One of those being treated is a 60-year-old woman, who sustained minor injuries due to a "projectile", it writes on Telegram.
Lebanon's state-run National News Agency reports that Hezbollah today announced an air attack on the Liman barracks, north of Nahariya, as part of a wider set of strikes.
The Israel Defense Forces (IDF) says it has intercepted more than 10 missiles launched from Lebanon at Israel and its forces operating in southern Lebanon since this morning.
The military also said earlier today it was expanding its operations in the south of Lebanon.

We’ve verified footage showing the aftermath of what appears to be an Israeli strike in the small southern Lebanese town of Sir el-Gharbiya.
The video shows rubble where a building once stood and damage to the wall of a neighbouring structure. It is not clear what the intended target was.
We’ve confirmed the location of the footage and verified that it was first shared online earlier today, indicating that it’s recent.
Separately, the Israeli military says it is close to capturing the Hezbollah stronghold of Bint Jbeil in southern Lebanon.
Let's turn now to the situation in Lebanon, where fighting has continued despite a ceasefire between the US and Iran, which Israel says does not apply to its campaign against Hezbollah.
According to the latest figures from Lebanon's public health ministry, 2,089 people - including 166 children - been killed in the country since 2 March, reports the state-run National News Agency.
An additional 6,762 people have been injured, it adds.
Back in the UK Parliament in London, Prime Minister Keir Starmer has just finished updating MPs on the situation in the Middle East. Here's a quick rundown of what he said:
Bernd Debusmann Jr
Reporting from the White House
As we've reported, Donald Trump has threatened to strike forcefully any small Iranian "fast attack ships" that threaten the US blockade.
As Trump alluded to, most of the US strikes focused on Iranian naval targets have been larger vessels and submarines, which were seen as strategically important targets to ensure American military dominance in the Persian Gulf.
But for years - decades even - military experts have warned that smaller, much more difficult to detect Iranian boats could also pose a challenge, potentially operating much more as an asymmetric "swarm" than a larger, conventional naval target.
The US has, however, for months now been striking small boats closer to home, both in the Caribbean and Eastern Pacific as the Trump administration moved to stem the flow of illegal drugs passing through the region on their way to lucrative drug markets in the US.
While dozens of these strikes have been conducted, it has been a slow burn, with US Southern Command announcing single strikes as they are conducted. At most, they have amounted to a handful in a single week during busier periods.
Just yesterday, for example, the Pentagon announced two separate strikes in the Pacific, killing five people.
Trump might see this as a model that can be sustained over time to maintain pressure on Iran without a full-fledged return to the combat operations that we saw during earlier in the conflict.
Image source, ReutersIranian "attack ships" will be "eliminated" if they approach US naval blockade, Donald Trump says in a new post on Truth Social.
"Iran’s Navy is laying at the bottom of the sea, completely obliterated - 158 ships. What we have not hit are their small number of, what they call, “fast attack ships,” because we did not consider them much of a threat," Trump writes.
"Warning: If any of these ships come anywhere close to our BLOCKADE, they will be immediately ELIMINATED, using the same system of kill that we use against the drug dealers on boats at Sea."
Keir Starmer is delivering a statement on the Middle East in the UK Parliament - to follow along, tap the watch live icon at the top of the page.
It comes shortly after Trump's threatened blockade of Iranian ports came into effect - which the prime minister earlier said the UK was "not supporting".
Image source, ReutersPakistani Prime Minister Shehbaz Sharif says efforts are ongoing to resolve the conflict between the US and Iran.
It comes after negotiations between the two nations - held in Pakistan's capital, Islamabad, over the weekend - failed to amount to a deal.
"The ceasefire is still holding and, as I speak, full efforts are under way to resolve the outstanding issues," Sharif tells his cabinet, according to translation by the AFP news agency.
Ships should be prepared to encounter the US blockade, the UK Maritime Trade Operations (UKMTO) has warned in a new advisory.
The note to seafarers urges any vessels in the area to "maintain heightened situational awareness" and that more specific guidance is to follow.
The advisory says additional guidance for mariners regarding "how these measures will be applied in practice, including routing, verification and authorised transit producers, are in development".
UKMTO encourages anyone sailing the Gulf, Gulf of Oman, and the Arabian Sea east of the Strait of Hormuz to expect military presence and possible interception.
"These access restrictions apply without distinction to vessels of any flag engaging with Iranian ports, oil terminals, or coastal facilities," UKMTO said of the threatened blockade.
It adds: "Further clarification is expected to be provided through subsequent advisories as information becomes available."
It's 10:00 ET (14:00 GMT / 15:00 BST).
This is the time US President Donald Trump gave as the deadline for the start of a US imposed naval blockade of ships entering or leaving Iranian ports.
We'll bring you the latest on this story, and the impact of the blockade, as soon as we have it.
We're minutes away from President Trump's deadline for a naval blockade of Iranian ports. It's unclear exactly what might happen next, but here is what we know:

reporting from the White House
It's a busier than normal morning at the White House ahead of Donald Trump's 10:00 ET (14:00 GMT / 15:00 BST) deadline for a naval blockade of Iranian ports.
On the driveway near the press area, reporters - including many from Middle Eastern media outlets - have been broadcasting since early this morning.
As things stand, we have little expectation of seeing Trump in person or on camera today. His official schedule shows that all his events are closed today, including a dinner this evening with King Willem-Alexander and Queen Máxima of the Netherlands.
There are many unanswered questions on how the blockade will be implemented, what it will mean going forward and what exactly the Trump administration hopes to achieve.
According to US Central Command, the blockade will be enforced "impartially" against all vessels entering or departing Iran's ports and coastal waterways.
Domestically, the blockade could present something of a challenge for Trump. Oil prices have again surged past $100 a barrel, and prolonged high prices could upset a US electorate that is broadly concerned about high prices and among whom the war in Iran has proven unpopular.

BBC Verify has been checking satellite imagery to get an idea of which US Navy warships are in the Middle East after President Donald Trump said a blockade of Iran-linked ships would come into effect at 14:00 GMT (15:00 BST) today.
Satellite imagery from Saturday shows the USS Abraham Lincoln aircraft carrier positioned at the eastern edge of the Gulf of Oman, roughly 200km (124 miles) to the south of the Iranian coast.
This is the closest to the Gulf that we have observed the nuclear-powered warship since the start of the war.
Two other nearby warships visible in the imagery are consistent in size and shape with US Navy guided-missile destroyers.
They are likely to be part of the Lincoln’s carrier strike group, but we cannot identify exactly which vessels are visible.
