The US military has rejected Iran’s claim that its IRGC captured an advanced US underwater drone in the Strait of Hormuz, saying it maintains “positive control” of all its drone assets and calling Tehran’s claim “clearly desperate”.

Meanwhile, Donald Trump said the US had transported a record amount of oil through Hormuz and expected more talks with Iran this week.

Oil prices rebounded after Trump rejected Iran’s proposal to reopen the strait, while Iranian Foreign Minister Abbas Araghchi said Tehran was prepared for war to resume, “even if it comes to a doomsday war”.

Iran’s IRGC has claimed that it captured a US Remus 600 unmanned underwater drone in the Strait of Hormuz and handed it to specialists for data recovery.

According to Tasnim news agency, the IRGC said: “IRGC Navy forces successfully captured an advanced unmanned underwater vehicle (UUV) belonging to the US terrorist army.”

It added: “The IRGC Navy firmly declares that the Strait of Hormuz is closed [to unauthorised traffic].”

Iranian foreign minister Abbas Araghchi said Tehran is prepared for a “doomsday” war with the US but is keeping diplomacy open to avoid missing a chance for peace.

“If you ask us, there is no reason why we should go back to diplomacy, but I am still trying diplomacy because I think we shouldn’t miss any chance for peace,” Araghchi said.

“We are ready to negotiate as much as we are ready to face any challenge … We stand firm in the face of any aggression against us, even if it comes to a doomsday war.”

Iran has proposed reopening the Strait of Hormuz and resuming nuclear talks if Washington meets its conditions, but president Donald Trump rejected the proposal.

Araghchi said: “Only a negotiated solution can break this deadlock.”

Meanwhile, Iran’s IRGC claimed it captured a US Remus 600 underwater drone in the Strait of Hormuz.

Donald Trump has said he expects talks with Iran will resume this week as “they want to make a deal”.

He told Axios on Sunday: “I expect more talks with Iran [this week]. They want to make a deal, but it is not the deal that I want to make.

“It is what we would have maybe agreed to a year ago. They overplayed their hand.”

Asked if he is considering resuming strikes against Iran, Trump said: “I am always thinking about it.”

He told Fox News on Sunday that more strikes were possible.

Iranian foreign minister Abbas Aragchi has insisted a diplomatic solution is the only option, syaing: “Only a negotiated solution can get them out of this deadlock.”

Iran’s Islamic Revolutionary Guard Corps (IRGC) has claimed its forces seized a US drone in the Strait of Hormuz.

Spokesman Hossein Mohebbi said the vital waterway was “not only open, but a hunting ground for the IRGC Navy targeting American submarines”

“The second catch has been reeled in, this time the Mk 18 Mod 2 Kingfish; an advanced, autonomous AUV equipped with sonar and precision navigation, worth several million dollars,” he said.

“It’s not just a hunt; it’s a trophy of technology and intelligence.”

Donald Trump has refused to rule out further attacks on Iran, but insisted the US would most likely win the war soon.

Asked by Fox News on Sunday if strikes in the coming weeks were an option, he said: “I don’t want to say that. I don’t want to say that. I mean, it’s possible, but I just don’t want to say that.

“I think what’s going to happen is we’re going to win this war very soon.

“We’ve already won it really from a military standpoint,” he added.

“But that doesn’t mean we’ve stopped that.”

UK Defence Secretary Wes Streeting said he had been “working closely with our American friends” in relation to a major incident outside the RAF Fairford airbase and that he had been in touch with US Defense Secretary Pete Hegseth.

He told a fringe event at the Labour Party conference: “This is my first experience as Defence Secretary of responding live to President Trump, and I’m sure it won’t be the only occasion.

“I’m sure you will understand that I’m not going to comment on a live operation and operational security matters.

“I don’t think it will come as a surprise to anyone that, given the importance of Fairford, not just to the United Kingdom but to the United States, we’ve been working closely with our American friends, and I’ve been in touch during the course of today with my counterpart Pete Hegseth.”
