The White House says Donald Trump will cut short his Group of Seven (G7) meeting and return to Washington tonight, citing the Middle East situation
Trump will likely skip planned meetings with the Ukrainian and Mexican presidents on Tuesday
He is also not expected to sign the G7 statement on the Iran-Israel conflict, despite other leaders' plan to call for de-escalation and protection of civilians
This comes after Trump and Sir Keir Starmer have signed a tariff deal between the US and the UK at a meeting during the G7 summit
Earlier, the US president called it a mistake to expel Russian President Vladimir Putin from the group in 2014, then called G8

The press conference between Carney and Trump has now ended, as Carney tells reporters the two leaders "actually have to start the meeting".

Trump is also asked about the possibility of allowing China to become a G7 member.
When the prospect is mentioned by a reporter during the presser, Trump responds: "That's not a bad idea."
He quickly pivots to point out that the G7 used to be the G8, before Russia was ousted from the group by former US President Barack Obama and other world leaders in 2014.
He said Vladimir Putin "was very insulted" by the move.
Responding to a question from reporters, Trump is now speaking about Immigration and Customs Enforcement (ICE) deportations.
He claims major cities like Chicago are "overrun with criminals," and says that ICE raids on major cities like New York and Los Angeles are a "major focus".
In a post on Truth Social yesterday, Trump called on federal agencies to "do all in their power" to deliver "the single largest mass deportation programme in history", naming Los Angeles, Chicago and New York as specific targets.
Trump returns to his earlier comments about Russia, adding that "too much water has gone over the dam" to invite Russia back to the group.
He maintains his view that removing Putin was a mistake, and blames his predecessor Barack Obama and former Canadian Prime Minister Justin Trudeau for doing so.
Trump is asked if he feels a US-Canada trade deal was achievable, after weeks of what appear to be stalled negotiations.
"I'm a tariff person. I've always been a tariff person," Trump says.
"I think Mark has a more complex idea, but also very good. We're going to take a look at both."
Carney says the G7 is "nothing without US leadership".
Trump responds, saying that the G7 was formally the G8, and former President Barack Obama and former Canadian Prime Minister Justin Trudeau didn't want Russia as a member.
He says if Russia was still a member, there would be no war in Ukraine. Not having the country at the table makes it "more complicated", he says.
Trump and Carney's bilateral meeting at the G7 in Kananaskis, Alberta, has started.
The Canadian PM wishes the US president a happy birthday, and also congratulates him on the 250th anniversary of the US Army.

At the G7 in Alberta
This is a big moment to kick off the G7 - a sit down between host Mark Carney and Donald Trump.
By all accounts, Carney and Trump have been getting along. The two met last month in Washington to launch trade and security talks following the recent Canadian election.
There were some awkward moments during their Oval Office meeting in May, when Carney pushed back on Trump’s remarks about making Canada the 51st US state. But in Canada, the PM was praised for how he handled that high-stakes meeting.
“As you know from real estate, there are some places that are never for sale,” he told the US president.
There are also ongoing trade tensions over Trump's tariffs, so this meeting will be closely watched.
Will Trump continue to make remarks undermining Canada’s sovereignty on its own soil? Will the pair reveal any developments on their talks?
And for the world’s media who have descended on this picturesque mountain town in Alberta, does it offer any hints as to how the next 48 hours will unfold?

Image source, ReutersLeaders of the world’s richest democracies are gathering in the Canadian Rockies for the G7 summit, where the conflict in the Middle East will overshadow everything.
There were handshakes and informal meetings last night and today brings the first full day of formal sessions.
Mark Carney, the Canadian prime minister who is chairing the summit, will be meeting Donald Trump soon – with relations between the two in a difficult place over trade tariffs and Donald Trump’s continued insistence that Canada should become America’s 51st state.
There will be an expectation that the G7 will attempt a show of unity over the conflict between Israel and Iran, But unity could well be elusive.
The problem here is that these countries are on a spectrum of opinion when it comes to their attitudes to the Middle East. On the one hand, the United States and Germany remain staunchly pro-Israel. On the other, Japan, and to some extent Canada, have expressed deeper concern about what is unfolding. The rest sit somewhere in the middle.
That makes finding a common position difficult. Especially because the other leaders won’t know exactly what Donald Trump’s attitude is – as he’s sent a number of mixed messages in recent days.
While we await this face-to-face meeting between Trump and Carney at the G7, let us take you back to the last time the pair saw each other in early May.
The meeting in the Oval Office was generally warm, but it did have some interesting moments as talks turned Trump's threats to Canada's sovereignty, as well as tariffs.
Watch a recap in the video below.

Image source, AFP via Getty ImagesCanada chairs the G7 this year and is hosting some of the world's wealthiest countries. It has promised a set of streamlined priorities focused around the global economy and security.
It's Prime Minister Mark Carney's first major international gathering as Canada's leader.
Here are five challenges ahead:
Iran derails plans - This summit was set to be a test of his ability to meet three lofty goals he advanced for Canada - but now the Iran issue has suddenly shot to the top of the G7 agenda, a subject on which finding agreement will be tricky.
The Trump factor - The summit is taking place amid a global trade war started by Trump, who is using tariffs as a way to rebalance trading relationships.
Avoiding a walkout like in 2018 - This will be Trump's second time in Canada as US president, the first being a discordant summit in Charlevoix, Quebec, in 2018 shortly after he slapped steel and aluminium tariffs on Canada, Mexico and Europe.
Forest fires, AI, critical minerals and Ukraine - Canada's priorities for the confab are sharply focused on building stronger economies and strengthening peace and security, including harnessing the power of artificial intelligence and fortifying critical mineral supply chains.
Geopolitical minefields - As host, Canada has invited leaders not permanently attached to the seven-member group, including India's Narendra Modi - amid deeply strained relations between the two countries.

US President Donald Trump is in Kananaskis, Alberta, in western Canada for the G7 summit where he will shortly meet with Canadian Prime Minister Mark Carney.
This is Trump's first visit to the US' northern neighbour since he threatened Canada's sovereignty and slapped steep tariffs on products from Canada.
While his rhetoric appears to have softened of late, this is still a sensitive moment for relations between the two allies.
