US intervention 'would be recipe for all-out war in Middle East', Iran warns, as Trump considers military action
Iran has warned American involvement in its war with Israel would spell "all-out war" in the Middle East.

It comes as Donald Trump has called for the "unconditional surrender" of Iran - amid escalating tensions in the Middle East.
According to reports from American news outlets NBC and CBS, Trump is considering joining Israel in attacking Iran, as officials say the US president is considering a US strike on the country.
But, speaking on Wednesday, an Iranian spokesman warned American involvement could lead to "all-out war" in the region.
The spokesperson added Iran would not hesitate to attack the US if it joined Israel.
"We will not show any reluctance in defending our people, security and land - we will respond seriously and strongly, without restraint," he said.
One possible location the US President is considering striking is Fordow, an underground nuclear site which Iran allegedly uses to enrich uranium.
The site is believed to be at the heart of Iran's nuclear programme, according to sources who spoke to CBS, which include senior US officials.
Fordow is located almost 300 feet underground inside a mountain, and is protected by heavy fortifications and air defences.
Experts believe it is where Iran has been enriching uranium for weapons purposes, which hasn't yet been proven.
It comes just hours after the US president claimed to know the location of Iran's Supreme Leader, Ayatollah Ali Khamenei.
Writing on his Truth Social platform, Mr Trump said: "We know exactly where the so-called 'Supreme Leader' is hiding.
"He is an easy target, but is safe there - We are not going to take him out (kill!), at least not for now.
"But we don't want missiles shot at civilians, or American soldiers. Our patience is wearing thin."
Without further explanation he also wrote "UNCONDITIONAL SURRENDER!" on the platform.
Speaking from the G7 in Canada on Tuesday, Prime Minister Sir Keir Starmer insisted British people should not feel unsafe with President Donald Trump in the White House amid fears over conflict in the Middle East.
Reports suggest around 40 additional US air force jets have now arrived in the UK and Europe, comprising of stealth fighter bombers and air to air refuellers amid escalating tensions with Iran.
It comes as two unnamed US officials told Reuters on Monday that the jets were there “to provide options to President Donald Trump as Middle East tensions erupt into conflict between Iran and Israel.”
It's a stance reinforced by JD Vance, who took to X to deliver a lengthy monologue praising the US Presidents "amazingly consistent' opposition to Iranian enrichment.
"The president has made clear that Iran cannot have uranium enrichment. And he said repeatedly that this would happen one of two ways--the easy way or the "other" way," Vance insisted.
"He may decide he needs to take further action to end Iranian enrichment," he continued.
"That decision ultimately belongs to the president. And of course, people are right to be worried about foreign entanglement after the last 25 years of idiotic foreign policy."
The move follows Trump's two-day deadline issued to Iran, as he vowed to bring a "real end" to Tehran's nuclear programme.
Starmer later insisted Trump had been on “good form” at the G7.
Donald Trump has declared he wants "better than a ceasefire" and said he wants a "real end" to Iran’s nuclear threat.
Speaking to reporters on board Air Force One late on Monday, Mr Trump said: “I didn't say I was looking for a ceasefire.”
He said he wants a ‘real end’ with Iran to give up “entirely” its ambitions to have nuclear weapons.
Mr Trump added he hoped the Iranian nuclear programme would be "wiped out long before" US involvement was required.
“The Israelis aren't slowing up their barrage on Iran,” CBS reported the president as saying. “You're going to find out over the next two days. You're going to find out. Nobody's slowed up so far.”
Trump's comments came just hours before Israel launched a fresh wave of strikes at the Iranian capital of Tehran.
The International Atomic Energy Agency (IAEA) said it believes Israeli air strikes on Iran's Natanz enrichment site have had "direct impacts" on the facility's underground centrifuge halls.
The strikes are part of an air campaign Israel launched against its long-time enemy five days ago, which it said was targeting Iran's military and nuclear programme.
But several residential buildings have also been hit in Tehran, as more than 220 people have been killed in Iran.
This marks the first time the UN's nuclear watchdog has assessed damage from the strikes in the underground parts of Natanz, which is the main enrichment facility of Iran's nuclear programme.
"Based on continued analysis of high-resolution satellite imagery collected after Friday's attacks, the IAEA has identified additional elements that indicate direct impacts on the underground enrichment halls at Natanz," the agency said.
Trump said he warned "everyone should evacuate Tehran" - as it was announced he would be departing the G7 leaders' summit early due to the situation in the Middle East.
The conflict between Israel and Iran has been top of the agenda at the summit of wealthy democracies, taking place in Canada.
In a post on Truth Social on Monday, Mr Trump criticised Iran for refusing to agree to a nuclear deal with his administration.
"What a shame, and waste of human life. Simply stated, IRAN CAN NOT HAVE A NUCLEAR WEAPON," he wrote.
"I said it over and over again! Everyone should immediately evacuate Tehran!"
He later added: "AMERICA FIRST means many GREAT things, including the fact that, IRAN CAN NOT HAVE A NUCLEAR WEAPON. MAKE AMERICA GREAT AGAIN!!!"
A new round of nuclear talks scheduled for the weekend between the US and Iran were cancelled after Israel's missile strikes.
Later on Monday, White House press secretary Karoline Leavitt announced on X that Mr Trump would be leaving the summit early, following a dinner with heads of state.
"Much was accomplished, but because of what's going on in the Middle East, President Trump will be leaving tonight after dinner with Heads of State," she said.
Downing Street declined to comment on Mr Trump's early exit.
In a statement agreed at the summit, G7 leaders described Iran as "the principal source of regional instability and terror" as conflict rages in the Middle East, adding they "affirm that Israel has a right to defend itself".
The statement, agreed before Mr Trump left the conference early on Monday evening, also includes a call for a "ceasefire in Gaza".
The statement said: "We, the leaders of the G7, reiterate our commitment to peace and stability in the Middle East.
"In this context, we affirm that Israel has a right to defend itself. We reiterate our support for the security of Israel. We also affirm the importance of the protection of civilians.
"Iran is the principal source of regional instability and terror. We have been consistently clear that Iran can never have a nuclear weapon. We urge that the resolution of the Iranian crisis leads to a broader de-escalation of hostilities in the Middle East, including a ceasefire in Gaza.
"We will remain vigilant to the implications for international energy markets and stand ready to coordinate, including with like-minded partners, to safeguard market stability."
Iran said at least 224 people had been killed in the country since strikes began on Friday, while Israeli officials said 24 people had been killed and more than 500 injured.
The back-and-forth between Israel and Iran has raised concerns about all-out war between the rival nations.
The latest conflict kicked off on Friday, when Israel launched an attack on top Iranian military leaders and the country's nuclear programme.
Following this, Trump then blasted French President Macron over his early exit, saying he "always gets it wrong".
"Publicity seeking President Emmanuel Macron, of France, mistakenly said that I left the G7 Summit, in Canada, to go back to D.C. to work on a "cease fire" between Israel and Iran. Wrong!
"He has no idea why I am now on my way to Washington, but it certainly has nothing to do with a Cease Fire.
"Much bigger than that. Whether purposely or not, Emmanuel always gets it wrong. Stay Tuned!"
Iran retaliated by firing waves of missiles at Israel.
It comes after Sir Keir Starmer urged British nationals in Israel to register their presence there as countries step up efforts to bring back stranded citizens.
The Foreign Office has advised against all travel to Israel, but Britons already in the country now face difficulties getting home, with the airspace closed due to the conflict with Iran.
The Prime Minister said the UK was issuing advice for British citizens in Israel to register their presence.
"All of us are giving advice to our citizens for British nationals in Israel, we're giving advice today to register their presence, so there will be a portal for that," he said.
Downing Street said its key message to British nationals in Israel was to stay near shelter and follow the advice of local authorities.
