If you're just tuning in, here's a brief rundown of what happened earlier: 

• Donald Trump and Volodymyr Zelenskyy spoke in the Oval Office, where the US president did not rule out sending US troops to Ukraine as part of a peacekeeping deal
• Trump and Zelenskyy were joined by a contingent of European leaders for multilateral talks
• A hot mic caught Trump telling Emmanuel Macron about a possible deal
• As the leaders met in the US, Vladimir Putin reportedly hit the phones for diplomatic talks with his own allies
• Trump paused his talks with the gathered European leaders to call Putin and arrange for him to meet with Zelenskyy

If you'd like to read more about the talks, Brad Ryan has put together a wrap of the day's events.  

The White House has released a photo taken of Donald Trump during his call with Vladimir Putin earlier. 

The two leaders reportedly spoke for about 40 minutes. 

Vladimir Putin's special envoy for investment and economic cooperation, Kirill Dmitriev, said Monday was an "important day of diplomacy".

In a post on X, Dmitriev said the day had a focus on "lasting peace" instead of a temporary ceasefire, and included an emoji of a white dove.

Donald Trump says he has discussed "the massive Worldwide problem of missing children" with European Commission President Ursula von der Leyen. 

"This is, likewise, a big subject with my wife, Melania," he wrote in a post on Truth Social. 

"It is a subject at the top of all lists, and the World will work together to solve it, hopefully bringing them home to their families!"

As we reported earlier, von der Leyen mentioned during the summit the issue of Ukrainian children who were allegedly abducted by Russia. 

"As a mother and grandmother, every single child has to go back to their family," she said.

"This should be one of our main priorities also in this negotiation, to make sure the children come back to Ukraine, to their families."

Trump was seen handing Russian President Vladimir Putin a letter penned by First Lady Melania Trump when they met in Alaska last weekend, which discussed the impact of the war on children.

UK Prime Minister Keir Starmer says talks made "real progress" today. 

He says there were two material outcomes from the summit: 

• The US will now work with a coalition of 30 countries already coordinating on security guarantees; and 
• Ukraine and Russia's leaders agreed to engage in talks, followed by a trilateral meeting with US President Donald Trump. 

"That is a recognition of the principle that on some of these issues, whether it's territory or the exchange of prisoners, or the very serious issue of the return of the children, that is something where Ukraine must be at the table," he told the press. 

"They're positive outcomes, there was real sense of unity. We made real progress today." 

Following the talks today, NATO Secretary General Mark Rutte appeared on Fox News for an interview with Laura Ingraham. 

He opened by lauding US President Donald Trump, describing him as "a pragmatic peacemaker". 

"Without President Trump, this deadlock with Putin would not have been broken," he said. 

"He was the only one who could do this."

Ahead of the press conference in the East Room earlier, Donald Trump was caught on a hot mic, whispering to French President Emmanuel Macron. 

"I think he wants to make a deal," he can be heard telling Macron. 

"I think he wants to make a deal for me; you understand that? As crazy as it sounds."

It's not immediately clear who Trump was referring to. 

Finnish President Alexander Stubb has commented after the White House talks and shared his scepticism over the Russian president's commitment to the process.

According to Reuters, Stubb told reporters "we will see if [Vladimir] Putin has the courage to come to such a meeting", adding "he cannot be trusted".

Stubb said Trump "felt it was a good idea to call Putin" and propose a bilateral meeting between the Russian and Ukrainian leaders.

Stubb said today's White House talks were "constructive" and that a "coalition of the willing has already worked on security guarantees" that will be "ironed out" in the next week or so.

However, Stubb said there was "nothing concrete" about US participation in those security guarantees.

Ukrainian President Volodymyr Zelenskyy gave a similar time frame when he spoke to reporters as well.

"Security guarantees will probably be 'unpacked' by our partners, and more and more details will emerge," he said.

"All of this will somehow be formalised on paper within the next week to ten days".

An English-speaking journalist managed to get one question in during Volodymyr Zelenskyy's Ukrainian language press conference that wrapped moments ago. 

The journalist was told the event was for Ukrainian press, but the president obliged the question. 

Switching to English, he said Ukraine is "ready for a trilateral meeting" with Putin and Trump.

Zelenskyy said it was Russia that first suggested Ukraine and Russia meet one-on-one, followed by a three-way meeting that would include Donald Trump.

Volodymyr Zelenskyy has been pressed multiple times on what the security guarantees look like at this stage of the negotiations. 

He was asked if US boots on the ground were part of the discussion. 

"We are talking about the coalition of the willing, we are talking about 30 countries. Some would be ready to talk about military presence. Some probabaly we are going to talk about intelligence, about the skies, about the seas. 

"Some don't have the constitutional rights [to help with a military presence] or have the money, some will have other contributions."
