Donald Trump told G7 leaders Iran is 'about to surrender,' officials claim

Two officials claim Mr Trump said: "Nobody knows who is the leader, so there is no one that can announce surrender."

Mr Trump also mocked Iran's new supreme leader Mojtaba Khamenei as a "lightweight", having previously suggested he would be "unacceptable" for the regime to continue.

The Iranian supreme leader, who succeeded his father Ali Khamenei after his death on February 28, released a message vowing to avenge "martyrs" yesterday.

The 56-year-old also vowed to open new fronts in the war "where the enemy has little experience and is highly vulnerable".

However, reports suggest Mojtaba Khamenei is leading the rogue state despite being critically wounded in an air strike.

He is said to have lost at least one leg and suffered serious stomach damage.

It was also claimed the new ayatollah has been induced into a coma.

Despite Mr Trump's confidence at the virtual G7 meeting, other world leaders urged the US President to end the war quickly.

There have been particular concerns about trade flows being adversely impacted by the Strait of Hormuz and oil prices being pushed above $100 a barrel.

However, Axios's report claimed Mr Trump remained "ambigious and non-committal" about his objectives and the timeline for ending the conflict.

The US President has been accused of mixed messaging on Iran since launching Operation Epic Fury with Israel last month.

Mr Trump declared the war is "pretty much complete" on March 9, just 24 hours after US Defence Secretary Pete Hegseth claimed: "This is only just the beginning."

He also said the US claimed victory in the "first hour" shortly before admitting: "We've got to finish the job."

The unknown status of Mojtaba Khamenei continues to complicate the situation.

Iranian officials categorically denied Ali Khamenei had died on February 28, with Tehran backtracking hours after Mr Trump publicly announced his death.

However, in his first statement since becoming the new ayatollah, Mojtaba Khamenei said: “I assure everyone that we will not refrain from avenging the blood of your martyrs.

"The retaliation we have in mind is not limited only to the martyrdom of the great leader of the Revolution; rather, every member of the nation who is martyred by the enemy constitutes a separate case in the file of revenge.”

He added: “Our sincere thanks go to our brave fighters who, at a time when our nation and beloved homeland have been unjustly attacked by the leaders of the front of arrogance, have blocked the enemy’s path with their powerful blows and dispelled their illusion of being able to dominate our beloved country or possibly divide it.”

Meanwhile, the G7 meeting appeared to expose Mr Trump's fractured relationship with Sir Keir Starmer.

The pair had struck up an unusual relationship following Mr Trump's return to the White House, with the US President consistently refusing to criticise the Prime Minister.

However, the G7 meeting was said to have included a remark about the UK's initial refusal to allow the US to use British bases for strikes on Iran.

"You should have proposed it before the war — now it is too late," Mr Trump said.
