The memorandum of understanding (MoU), an agreement between Iran and the US to work towards ending the conflict, is less than a month old.

The ceasefire has technically been in place since early April, although both sides have accused the other of violating it during previous tit for tat strikes.

By saying the ceasefire is "over", but that the talks are not, Donald Trump’s comments seem to both close the door and keep it open a crack.

They are not dissimilar to his previous posts in the period after a ceasefire was agreed but before the MoU was signed - a carrot and stick approach, promising Iran much if it signed a deal, and threatening destruction if it didn’t.

They also show his frustration. The question is, will that mean a return to hostilities?

Tanker company Bahri has confirmed one of its vessels, Wedyan, was "involved in an incident" while transiting the Strait of Hormuz on Tuesday.

"We are pleased to confirm that all crew members and personnel on board are safe and accounted for with no reported injuries," a statement reads.

Bahri says the vessel's cargo is secure and that the ship remains "in a seaworthy condition".

Earlier, BBC Verify earlier confirmed that Wedyan was among the three ships targeted.

The US says it hit "over 80 targets" in its latest wave of strikes, which were in response to attacks on commercial ships in the Strait of Hormuz. There has been confirmation of strikes in the following places:

• The Iranian military says coastal bases and civilian facilities were struck in the provinces of Hormozgan and Mahshar
• More strikes hit Bandar Mashahr,south-west Iran - an Iranian soldier was killed by shrapnel, according to the Islamic Revolutionary Guards (IRGC)
• Iranian media reported strikes in the Bushehr region of south-west Iran

The places targeted are clustered around the coastline along the Strait of Hormuz.

Kuwait intercepted two ballistic missiles and 13 drones overnight, according to its defence ministry.

In a statement posted on X, official spokesman Major General Saud Abdulaziz Al-Otaibi says Kuwait's airspace was breached but the projectiles were shot down, with no injuries reported.

However, Kuwaiti authorities have since reported some power cuts.

Qatar has condemned "unjustified" Iranian attacks on Bahrain and Kuwait, which its foreign ministry says were a "blatant breach" of international law and the two countries' sovereignty.

Doha also emphasises the need to "pursue the path of dialogue and diplomacy, to de-escalate tensions, and to build upon the progress achieved under the memorandum of understanding".

As a reminder, Iran says it is targeting US military sites in Bahrain and Kuwait after American strikes against it overnight.

A short while ago, Donald Trump declared the ceasefire with Iran "over", though did leave some leeway for his negotiating team to continue talks with Tehran.

It's not the first time the US president has issued definitive statements about the agreement - here is what he has said previously.

• 8 April - US and Iran sign agree to a tentative two-week ceasefire
• 21 April - Trump says he doesn't want to extend the two-week ceasefire and says he "expects to be bombing" again soon. Later that day, he says US attacks have been called off after a request from Pakistan
• 8 May - Trump says the world will know the ceasefire is over when there is "one big glow coming out of Iran"
• 11 May - Days later, Trump says the ceasefire is on "massive life support"
• 11 June - Trump indicates the ceasefire is over, threatening to hit Iran "very hard", before calling off the strikes later that evening
• 17 June - As Trump signs an initial agreement to end the war, he says: "If they don't behave, we'll go right back to dropping bombs right smack in the middle of their head"
• 8 July - Trump says the ceasefire is "over" but says negotiators on both sides can continue to talk

Tensions have spilled over again in the Gulf, following a string of attacks on shipping in the Strait of Hormuz. It's the worst exchange of fire between the US and Iran since they signed a memorandum of understanding (MoU) to end the conflict on 17 June. Here's what's happened this week.

Monday

• The UKMTO says a tanker travelling through the Strait of Hormuz reported a fire after being hit by an unknown projectile

Tuesday

• In two separate incidents, tankers report being hit in the Strait of Hormuz. Iran has not directly claimed responsibility for either of these attacks, or the one on Monday
• The US military says it has "begun launching a series of powerful strikes against Iran", hitting more than 80 targets. This is in response to attacks on commercial shipping in the Strait of Hormuz in a "clear violation of the ceasefire", it says

Wednesday 8 July

Earlier

• Iran's Islamic Revolutionary Guard Corps announces it targeted US military sites in Bahrain and Kuwait
• Nato chief Mark Rutte calls the American strikes "absolutely necessary"
• But Iran's speaker Mohammad Bagher Ghalibaf accuses the US of breaching the agreement between the two countries

Moments ago

• US President Donald Trump says that the ceasefire with Iran is "over", telling reporters at the Nato summit in Ankara: "I don't want to deal with them anymore, they're scum"

Multiple strikes on the city of Bandar Abbas overnight were captured on video, with several explosions visible and flames seen rising over a facility.

It is not clear from the footage what was being targeted by the US.

The US military says it resumed strikes on Iran in response to attacks on three commercial vessels transiting the Strait of Hormuz.

The first ship cited by the US, Al Rekayyat, is a Qatar-owned liquefied natural gas (LNG) tanker. BBC Verify understands it was struck by a projectile off the coast of Oman on 6 July while transiting the strait.

The impact caused a fire on board, although no casualties have been reported. The vessel crossed with its automatic identification system (AIS) location signal switched off and was last identified in satellite imagery on 22 June near Qatar's main LNG export hub.

The second vessel, Wedyan, is a Saudi-owned crude oil tanker carrying Saudi crude. Its AIS signal has been switched off since 3 July.

The third mentioned by the US, Cyprus Prosperity, is a Liberia-flagged crude tanker which went through the strait with its location data switched on and was carrying oil to Fujairah port in the UAE.

UKMTO has confirmed three incidents but has not identified the vessels. The British maritime authority also says no casualties or environmental damage have been reported.

Oil traders have reacted quickly to Trump’s announcement that the ceasefire is “over”.

Just before he made those remarks, a barrel of oil was just under $76 (£57). At 0945 BST, it was over $78 (£58) and appears to be rising further.

As we reported earlier, oil prices had already been ticking upwards after Iran and the US traded strikes overnight.

Trump's comments on the US-Iran ceasefire began at around 09:15 BST, when a reporter at the Nato summit in Ankara asked "Is the ceasefire over? Is the ceasefire done? Is the MoU dead?" (the memorandum of understanding, which led to the ceasefire, was agreed last month).

Trump replied: "It's a very interesting question. To me, I think it's over.

"I don't want to deal with them anymore, they're scum. You know what scum is? They're scum. They're sick people. They're led by sick people. And they're vicious, violent people.

"And if they had a nuclear weapon, they'd use it. As far as I'm concerned it's over.

"I'll speak to our negotiators, they want to negotiate, they're good people. Steve Witkoff, Jared Kushner, but they have to come back to me. As far as I'm concerned, it's just a waste of time dealing with them. They're liars.

"We make a deal. If I make a deal with him [pointing at Nato Secretary-General Mark Rutte], we have a deal. He goes out, he talks. We [US and Iran] make a deal, everyone's agreed, no nuclear weapon.

"We make a deal. They [Iran] go outside, talk to the press, they say 'we never even talked about it'. There's something wrong with them. They're cuckoo. As far as I'm concerned, it's over."

Trump is then asked if talks will resume.

"I don't care, they can talk. But I think they're wasting their time. They're a bunch of lying guys."

Pressed further after declaring the US ceasefire with Iran "over", Trump says of his negotiating team: "They can talk, but I think they're wasting their time."

"Frankly, I don't want to waste my time with them," he adds.

Trump also says he will "let our wonderful negotiators keep talking if they want, but I don't see it".

Asked about the ceasefire between the US and Iran, Donald Trump says: "I think it's over."

He tells reporters at the Nato summit: "I don't want to deal with them anymore, they're scum."

"As far as I'm concerned, it's over," he adds. "It's just a waste of time dealing with them, they're liars."

Trump says negotiators from both sides "can talk" but are "wasting their time".

Trump praises Nato's secretary-general Mark Rutte, who he is speaking alongside, but says he is not "not happy" with the military alliance.

He says Nato allies "didn't want to help us with the number one state sponsor of terror, that's Iran".

"I'm very upset with Nato," Trump says, adding the US pays "too much, billions and billions of dollars too much".

Speaking at the Nato summit in Turkey, Donald Trump describes the Iranian regime as "evil people" and calls the administration "crazy", repeating the US position that Tehran can't be allowed to develop a nuclear weapon.

He points to attacks on ships in the Strait of Hormuz on Tuesday, as well as strikes against targets in Kuwait and Bahrain.

"These are evil sick people," the US president continues. "They're cancer, and you know what you have to do - you have to cut out cancer early."

Iran's Foreign Minister Abbas Araghchi has accused the US of a "flagrant violation" of the memorandum of understanding (MoU).

The US strikes, reinstatement of sanctions on Iranian oil sales and Israel's ongoing conflict with Hezbollah in Lebanon have rendered "important and fundamental parts of the understanding on the cessation of the war ineffective", he says in a statement.

He adds that Iran "will not hesitate" to defend its "integrity, national sovereignty, and national security".

In a warning to Gulf countries which host US military bases, Araghchi says Iran will "target the source and point of origin" of any attacks.

New strikes have taken place in the Iranian port city Bushehr this morning, two semi-official Iranian news agencies are reporting.

Multiple explosions have been heard in Bushehr, south-west Iran, and surrounding areas, the Mehr news agency reports.

Meanwhile, a senior security official in Bushehr says "enemy projectiles" have struck two military headquarters, one in Dashti County and one near the city of Choghadak, according to the Fars news agency.

No casualties were reported, the official adds.

There have also been reports of an attack on Kharg Island - a major oil terminal off the coast of Iran - which Mehr says are not true.

This is the worst exchange of fire between the US and Iran since the two countries signed their memorandum of understanding on 17 June.

But it does not, by itself, mean the tentative ceasefire has to end.

Neither nation wants a return to the full-scale conflict that raged for five weeks earlier this year.

It’s not clear why Iran targeted those three vessels transiting the Strait of Hormuz.

Possibly it was to test the US reaction. Possibly it was to try to force ships to use its new designated route.

The strikes on Iranian coastal positions by the US in response were intended as a deterrent for any further Iranian attacks.

But now Iran’s response - launching munitions at Bahrain and Kuwait - is an uncomfortable reminder that peace and tranquility have not yet fully returned to the Gulf.
