On Sunday, President Donald Trump told NBC Iran had agreed to a deal with the US during talks over the weekend.

He said: "They agreed to a deal yesterday, a perfect deal for us. No nuclear, no this, no that, no nothing. They gave up everything."

On Monday, Iran's foreign ministry spokesman called Trump's comments "absolutely untrue".

Esmail Baghaei says no topic other than the Strait of Hormuz was discussed during a meeting between the two countries in Oman on Saturday.

Mediators are continuing their efforts in negotiations between the US and Iran, he adds.

Iran's foreign ministry spokesman says the US-Iran deal has "entered a crisis".

Iranian state media quotes Esmail Baghaei as saying Iran's "defensive strikes" are solely against bases and facilities used by the US to attack the country.

"We will not hesitate in our self-defence," he adds, saying Iran cannot allow the US to use transit in the Strait of Hormuz to harm the country's sovereignty and security.

Baghaei says negotiations on Saturday were solely focused on the vital waterway, adding that Iran's goal was to ensure the safe passage of ships. But, he says, US pressure on Oman has hindered efforts.

As a reminder, ship-tracking data shows no vessels have transited the strait since yesterday evening.

On the memorandum of understanding - a 14-point deal signed on 17 June - Baghaei says Iran will not execute its commitments if the US fails to honour the agreement.

The UN secretary-general said on Sunday he was "deeply concerned" by the renewed military confrontations in the Gulf region, urging all parties to exercise "maximum constraint".

In the statement, made before a further set of US strikes overnight on Sunday, Antonio Guterres warned that a return to full-scale hostilities would have "catastrophic consequences".

He also called for the restoration of "full freedom of navigation" in the Strait of Hormuz.

The secretary-general's comments were criticised by Iranian Foreign Ministry spokesman Esmail Baghaei, who said on Sunday that Iran's strikes on US bases in the region were a "legitimate and lawful exercise of its inherent right to self-defence under international law".

He also called on Guterres to urge the countries in the region to stop allowing the US to use their territories "as launchpads for aggression against Iran".

No commercial vessels have crossed the Strait of Hormuz while broadcasting their location since yesterday evening, according to ship-tracking website MarineTraffic. Other ships may have crossed with their transmitters off.

On Sunday, the Iranian government’s Persian Gulf Strait Authority (PGSA) said transit through the waterway "is not currently possible" due to "illegal movements of the United States military forces in the region".

Eight commercial vessels including tankers, bulk carriers and cargo vessels, crossed the strait on Sunday - down from 21 on Saturday and 14 on Friday, according to preliminary data from maritime intelligence firm Kpler.

Of the eight that crossed yesterday, two broadcast their positions during the transit and both had crossed before the PGSA made its announcement.

The other six crossings recorded by Kpler were dark, meaning they did not broadcast their position while they were crossing the Strait of Hormuz.

Our colleagues at BBC Verify will continue to monitor vessels crossing the strait throughout the day.

The battle over control of the Strait of Hormuz has stalled movement towards ending the wider conflict.

Iran pledged to open the strait, according to the terms of its interim deal with Washington, but it has been firing on commercial vessels it says are using an unauthorised route.

The US military says its latest round of strikes has continued to degrade Iran’s ability to attack international shipping. And it insists that traffic is still able to flow through the strait.

The Trump administration needs that to happen to bring oil prices down ahead of midterm elections in November.

Attempts by mediators to resolve the dispute at the weekend failed – and it’s clear how important control of the strait is to Iran: more important than dozens of atomic bombs, senior Iranian officials have said.

It’s believed neither side wants to return to all-out war, but analysts say they are in a state of controlled escalation.

In our next post, we'll bring you an update on the tracking of ship movement in the strait.

European stock investors appeared to shrug off the latest news about military attacks between the US and Iran as the major markets all opened flat.

The FTSE 100 index of the largest firms listed in London, as well as its French and German equivalents, the Cac 40 and the Dax, were all flat in early trading, not moving since Friday's close.

US markets will open at 09:30 in New York (14:30 BST), but current bets on the future price of shares in that market suggest the S&P 500 index could be down by about half a per cent when share trading begins.

Meanwhile, oil prices jumped at the start of trading as Brent crude - the global benchmark wholesale oil price - surged almost 5% early on Monday to over $79 (£59) a barrel.

Iran's parliamentary speaker Mohammad Bagher Ghalibaf - who has been the country's chief negotiator with the US - said on Sunday the era of "one-sided deals is over".

He added in a post on X: "We told you: keep your word or pay the price. Reality is knocking."

Iran's foreign ministry also accused the US of causing "the return of insecurity" in the Strait of Hormuz.

Meanwhile, in a brief phone interview on Sunday, US President Donald Trump said to Reuters: "We're beating them up," referring to Iran.

From hopes of peace, to regular attacks - here's a recap on how we got here:

• 17 June - US and Iran sign a memorandum of understanding (MoU), supposedly putting an end to the conflict - and beginning a further 60 days of negotiations

• 26 June - The US launches fresh strikes on Iran after Donald Trump accuses the country of a "foolish violation" of its truce, following an attack on a cargo ship in the Strait of Hormuz
• 7 July - The US launches approximately 80 more strikes at Iran in response to attacks on ships in the Strait of Hormuz, while Iran targets US military sites in Bahrain and Kuwait
• 8 July - Trump declares the ceasefire with Iran "over", calling the country's leadership as "scum" and "cuckoo" - see our clip below
• 11 July - US officials demand that Iran publicly state the Strait of Hormuz is open
• 12 July - The US launches its latest wave of attacks on Iran following further attacks in the strait, with Iran retaliating through several strikes at US bases in the region

Iran's Islamic Revolutionary Guard Corps (IRGC) says it has attacked radar systems in Oman as part of its retaliatory strikes against the US, Iranian state media reports.

It follows earlier statements in which they said they had attacked sites in Bahrain, Kuwait and Jordan.

The attacks came in retaliation to overnight attacks made by the US on dozens of Iranian military installations.

Oil prices jumped at the start of trading, following news Iran had hit commercial ships in the Strait of Hormuz, with the US then carrying out more attacks on Iran.

One fifth of the world's oil and gas usually flows through the key waterway south of Iran which the country had effectively closed in response to the start of the US-Israel war with Iran at the end of February.

Brent crude, the global benchmark wholesale oil price, surged almost 5% early on Monday to over $79 a barrel.

Despite the rise, prices remain far below the near $120 a barrel peak reached during the height of the war.

Before the conflict began, oil was trading at around $70 a barrel.

Following overnight strikes by the US, Iran's Islamic Revolutionary Guard Corps (IRGC) says it attacked several bases linked to the US in Bahrain, Kuwait and Jordan.

Via Iranian state media, the group says it struck two US-linked air bases in Kuwait, as well as army infrastructure and a drone command centre in Bahrain, and the Prince Hassan Air Base in Jordan.

Bahrain's interior ministry has issued several warnings over the last four hours, urging citizens to head to safe locations.

The Jordanian military shot down four Iranian missiles that entered its airspace on Monday, a Jordanian source tells the AFP news agency.

Meanwhile the Kuwaiti military says it "intercepted hostile aerial targets" within the country's airspace.

In its first update, posted on Sunday evening, US Central Command (Centcom) said its strikes aimed to degrade Iran’s ability to "attack civilian mariners and commercial ships" in the Strait of Hormuz, after a series of attacks in the waterway.

In a separate post, published at 03:30 BST, Centcom said it had "completed" its attacks.

It said it had struck air defence-systems, coastal radar sites, naval vessels and missile and drone sites.

"The Strait of Hormuz is a vital maritime corridor for global trade. Iran does not control it," said Centcom.

"US forces are postured and prepared to ensure that freedom of navigation remains available to commercial shipping despite Iran’s continued unwarranted aggression."

The US said its attacks involved "fighter aircraft, naval vessels, one-way attack aerial drones, and one-way attack sea drones for the first time".

The US military has carried out a wave of strikes on Iran overnight - targeting dozens of Iranian military installations, including air-defence systems, coastal radar facilities, and missile and drone sites.

Iran's Islamic Revolutionary Guard Corps (IRGC) said it retaliated with strikes on US military bases in Kuwait, Jordan and Bahrain.

The US says the attacks are a response to Iranian attacks on commercial ships in the Strait of Hormuz - Iran says the waterway is closed until further notice, while the US insists it is open.

In a statement detailing Sunday night's strikes, Centcom said US forces are "postured and prepared to ensure that freedom of navigation remains available to commercial shipping".

In June, both sides agreed a ceasefire as part of a "memorandum of understanding" - but last week, Donald Trump said the ceasefire was "over", while calling Iran's leadership "scum".
