Mohammad Bagher Ghalibaf, the Iranian parliamentary speaker who led negotiations in Islamabad, has mocked Donald Trump in a post on X referencing US plans to blockade the Strait of Hormuz.

"Enjoy the current pump figures. With the so-called 'blockade', Soon you'll be nostalgic for $4–$5 gas," the post says, accompanied by a map appearing to show petrol prices around Washington DC.

In an earlier statement carried by Iranian outlets Ghalibaf said Iran will not "surrender under threats".

Oil prices jumped above $100 a barrel as energy markets reopened on Sunday after talks between the US and Iran ended without a new deal and Donald Trump said he would blockade Iranian ports.

Global benchmark Brent crude is up by 7.5% at $102.37, while West Texas Intermediate is 8.3% higher at $104.56.

The failure of negotiations at the weekend has raised concerns that the war will continue to deepen the energy crisis.

Three Iranian-flagged vessels have sailed through the Strait of Hormuz and into the Arabia Sea since Donald Trump announced the US would be blockading the strait, according to data from MarineTraffic.

US Central Command says the blockade will start on 13 April at 10:00 ET (14:00 GMT), and would be enforced against "all maritime traffic entering and exiting Iranian ports".

Three legal experts have told the BBC that a blockade could violate maritime law. One also questioned whether a blockade, which is enforced militarily, would violate the current ceasefire agreement.

At least 60 vessels have passed through the strait - an average of 10 a day - since the ceasefire was announced last Tuesday evening.

This is a significant increase from before the ceasefire, but still a fraction of the volume pre-war, when about 138 ships passed through the strait each day, according to the Joint Maritime Information Centre.

Iranian Foreign Minister Abbas Araghchi says Tehran engaged in "good faith" with the US during peace talks in Islamabad, Pakistan.

In a post on X, he adds: "When just inches away from 'Islamabad MoU', we encountered maximalism, shifting goalposts, and blockade."

He signs off: "Good will begets good will. Enmity begets enmity."

Centcom has said that a blockade of traffic entering and exiting Iranian ports will begin at 10:00 ET (14:00 GMT) on Monday.

In a post on X on Sunday, it says the blockade will be enforced "impartially against vessels of all nations entering or departing Iranian ports and coastal areas".

It also says that it will not block vessels in the Strait of Hormuz if they are heading "to and from non-Iranian ports".

The failure to find a solution to reopening the Strait of Hormuz is understood to be one of the reasons talks between the US and Iran broke down over the weekend.

After the talks concluded, US President Donald Trump said on Truth Social that the US would "begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz."

Later, Iran's Islamic Revolutionary Guard Corps (IRGC) Naval Forces said any military vessels that approach the Strait of Hormuz will be considered to be violating the ceasefire and "dealt with severely".

Centcom says the blockade will be enforced "impartially against vessels of all nations entering or departing Iranian ports and coastal areas".

It says this includes all Iranian ports in the Gulf, and the Gulf of Oman.

"CENTCOM forces will not impede freedom of navigation for vessels transiting the Strait of Hormuz to and from non-Iranian ports," the military says.

It adds more information will be provided to commercial operators through a formal notice before the start of the blockade."

Earlier on in a post on Truth Social, Donald Trump said the US would "begin the process of BLOCKADING any and all Ships trying to enter, or leave, the Strait of Hormuz."

US Central Command says a blockade of traffic entering and exiting Iranian ports will begin at 10:00 ET (15:00 BST) on Monday.

Benjamin Netanyahu’s social media account has posted a short video of the PM saying he has been visiting Israeli troops in southern Lebanon.

Speaking in Hebrew, he says recent Israeli operations to create a buffer zone - or a security strip - have "thwarted the threat of an invasion from Lebanon”, referring to Hezbollah fighters.

He says "tremendous work" has already been done by the military but vows there is "there is still more to do, and we are doing it”.

Mr Netanyahu says Israeli action in Lebanon is evidence that Israel has “essentially changed the face of the Middle East.” This action has been widely criticised though for the number of civilians killed.

The Lebanese health ministry says Israeli air strikes have killed more than 2,000 people since the start of the war.

Iran has said it will resume attacks - and end its ceasefire deal with the US - if Israel continues to bomb Lebanon.

Lebanon's health ministry says at least five people have been killed in Israeli strikes in Qana in southern Lebanon.

Three women were among the dead and 25 people were wounded, Lebanon's state-run National News Agency (NNA) reported the ministry as saying.

Pictures taken by AFP news agency show the destruction to the village, as well as emergency responders carrying a body from the rubble.

The Israel Defence Forces (IDF) has not commented on the reports.

Israel, which is continuing its campaign against Hezbollah despite a ceasefire between the US and Iran, carried out other strikes in southern Lebanon today.

Iranian President Masoud Pezeshkian says that an agreement with the United States "will certainly be found" if "the American government abandons its totalitarianism and respects the rights of the Iranian nation".

The post on X comes after Iranian media reported a read-out between Pezeshkian and Russia's Vladimir Putin in which it quoted the former as saying a deal with the US was "not out of reach".

Trump has said that direct talks with Iran in Islamabad failed because "Iran is unwilling to give up its nuclear ambitions". He then told Fox News: "I predict they come back and they give us everything we want."

After a diplomatic team led by Vice-President JD Vance tried, and failed, to reach a negotiated agreement to end the US war with Iran on Saturday, President Donald Trump had to decide his next move.

That came on Sunday morning, in a series of Truth Social posts.

The US will impose a naval blockade, he wrote.

"No one who pays an illegal toll will have safe passage on the high seas."

He also said that the US would continue clearing mines from the Strait of Hormuz in order to ensure a safe passage for allied shipping.

The US military, he added, was "locked and loaded" and prepared to resume attacks against Iran at an "appropriate moment".

He went on to say that while progress had been made in the 20-hour negotiations in Islamabad, Iran would not meet the US demand that it abandon its nuclear ambitions.

While his posts didn't have the apocalyptic bluster of last week's threat to end Iranian civilisation, they pose a number of new challenges – and risks – for the American side.

Mohammad Bagher Ghalibaf, speaker of Iran’s parliament who was the head of negotiations between Iran and the US in Pakistan, has issued a statement upon his return to Iran.

Responding to comments from US President Donald Trump, he says that “such threats have no effect on Iranians” and Iran will not “surrender under threats”.

According to reports by Iranian outlets, Ghalibaf has addressed Trump by saying that “if you fight, we will fight, if you come forward with logic, we will respond with logic.

"We will not submit to any threat. If they test our resolve once more, we will teach them an even greater lesson”.

Elsewhere in his remarks, Ghalibaf has said that Tehran had said from the beginning that they “do not trust the Americans” and that they must “earn” Iran’s trust because they attacked Iran twice during negotiations in less than a year.

The war that started on 28 February this year and the 12-day war back in June last year both began when Iran and the US were engaging in talks over Iran’s long-debated nuclear programme.

Iran’s Islamic Revolutionary Guard Corps (IRGC) Naval Forces says any military vessels that approach the Strait of Hormuz will be considered to be violating the ceasefire and "dealt with severely".

In a statement published by Iranian outlets by IRGC’s Public Relations quoting Naval Forces, it adds that “contrary to the false claims of some enemy officials”, the Strait of Hormuz is “open for the innocent passage of non-military vessels under intelligent control and management in compliance with specific regulations” of Iran.

The statement has not mentioned names of any ‘“enemy” officials but US President Donald Trump had said that US Navy will “blockade any and all ships” trying to enter or leave the Strait of Hormuz.

Omani Foreign Minister Badr Albusaidi has called for an extension to the ceasefire to allow for talks between the US and Iran to continue.

Donald Trump announced late on Tuesday night that a ceasefire would take place for two weeks, conditional upon the Strait of Hormuz being opened immediately.

Oman had been mediating nuclear talks between both countries before conflict broke out on 28 February.

Albusaidi said earlier this afternoon in a post on X that when he had met US Vice President JD Vance "just hours before the war began, I formed an impression that both he and the President had a genuine and strong preference to avoid the entanglements of war."

"So I urge that the ceasefire be extended and talks continue. Success may require everyone to make painful concessions, but this is nothing as compared to the pain of failure and war," he says.

Vice President JD Vance believes a deal with Iran remains possible - but left the talks in Islamabad after making Tehran a final offer because the regime appeared unwilling to agree to abandoning its nuclear programme, according to a US official.

Vance, who led the US delegation, left the talks convinced that Iran misunderstood the amount of leverage it has in negotiations with the Trump administration, said the official, who offered a summary of the talks on the condition that they not be named.

The negotiations lasted more than 21 hours, with Vance leading a US team that also included special envoy Steve Witkoff and President Donald Trump's son-in-law Jared Kushner.

The US and Iran did not reach agreement on a wide range of issues, the US official said.

According to the official, those issues including ending Iran's uranium enrichment, finding a framework for a broader peace that includes allies in the region, and a solution to reopen the Strait of Hormuz that does not include charging tolls.

Donald Trump told Fox News earlier the US got "just about every point we needed, except for the fact that they refused to give up their nuclear ambition".

The BBC understands the UK will not be involved in a US-led blockade of the Strait of Hormuz.

A spokesperson for the UK government says that the strait "must not be subject to tolling" and that Westminster is working on a "coalition to protect freedom of navigation".

The spokesperson says: “We continue to support freedom of navigation and the opening of the Strait of Hormuz, which is urgently needed to support the global economy and the cost of living back home.

"The Strait of Hormuz must not be subject to tolling.

"We are urgently working with France and other partners to put together a wide coalition to protect freedom of navigation.”

Donald Trump has also said Iran will come back to the negotiating table and "give us everything we want".

In the same earlier interview with Fox News' Sunday Morning Futures, Trump says US negotiators got "just about every point we needed, except for the fact that they refused to give up their nuclear ambition".

He asserts Iran hasn't "left the bargaining table".

"I predict they come back and they give us everything we want," he says.

During another moment in the interview, Trump threatens China with 50% tariff if it helps Iran's military. He also says that the price of oil and gas will eventually be lower following the conflict.

We can now bring you more from Donald Trump's conversation with Fox earlier this afternoon.

The US president also compared UK PM Keir Starmer to Neville Chamberlain.

Trump makes the criticism in his earlier Fox News interview, in which he says Starmer promised to "send equipment after the war is over".

"That's a Neville Chamberlain-type statement," he adds.

Starmer has previously said the UK was talking with international partners about a plan to return normal shipping to the Strait of Hormuz but has repeatedly refused to involve the UK in a wider war.

Trump has previously likened Starmer to Chamberlain, while also describing him as "no Winston Churchill", who came to office after Chamberlain.

Iranian President Masoud Pezeshkian says a deal with the US is "not out of reach" if the Trump administration abides by international law, the country's state broadcaster reports.

The remarks were carried in a reported read-out of a call between Pezeshkian and Russian president Vladimir Putin, carried in a Telegram post by Islamic Republic of Iran Broadcasting.

The call followed US-Iranian talks in Islamabad.

The US Navy will blockade the Strait of Hormuz, Donald Trump announced earlier, after talks in Islamabad failed to produce a deal between the US and Iran.

It's a critical shipping route through which roughly 20% of the world's oil and natural liquefied gas is transported.

The strait's geography has allowed Iran to use it as leverage throughout this war, selectively preventing vessels from passing through the narrow waterway and spiking oil prices in the process.
