Good evening
Thanks for following our live coverage of the war in Ukraine - that's all for today.
Before we go, let's round-up the key events from the day.
In the last few hours, we've been reporting on what Ukrainians are describing as a "massive" Russian drone attack on the city of Odesa.
At least three people, including a young girl, are injured there, but details are still sketchy.
Away from Ukraine itself, it's been another whirlwind day at the negotiating table.
In the UK, Sir Keir Starmer hosted several military leaders from Europe to speak about what a peacekeeping force for Ukraine could look like, while Donald Trump said a US-Ukraine minerals and rare earths deal thought dead would be signed "very shortly".
Join us in the morning for more updates.
Analysis: UK deploys prince in latest ploy to support Ukraine and its allies
A member of the British Royal Family has been visiting a Baltic state today to show support for the country and the troops based there - who are providing a deterrent to Russian aggression in the region.
Royal correspondent Rhiannon Mills has been reflecting on the Prince of Wales' visit...
Prince William's arrival in Estonia felt like the latest example of the Royal Family being right on the frontline of high-stakes diplomatic discussions.
There's been no attempt by the UK government and Foreign Office to shy away from whythe prince was deployed.
With Estonia sharing a border with Russia and being a big supporter of Ukraine, the government wants the prince to emphasise it's got the UK's full support, especially with anxiety rising over what a potential ceasefire might really mean.
As William visited a school, the Freedom School, set up in 2022 especially for Ukrainian students, he repeated the same message twice over - of praising Ukraine's resilience.

'America's global credibility is at stake over Ukraine'
America's global credibility is at stake over how its president deals with the war in Ukraine, Poland's foreign minister has told Sky News.
In a wide-ranging interview with Mark Austin, Radoslaw Sikorski also said that Vladimir Putin wants "all of Ukraine" and warned Donald Trump is "capable of changing his policy rather rapidly".
Poland has stood as one of Ukraine's fiercest allies throughout the war with Russia,
Sikorski said that Trump cares only about having success, but that the "credibility of the United States is staked on the quality of the solution".
Watch his full interview with Mark below...
Zelenskyy to head to Paris to meet with European leaders next week
French President Emmanuel Macron has confirmed he will host the next "collation of the willing meeting", and it now appears that there will be a Ukrainian presence.
Diplomats have told the Reuters news agency that he'll travel to France next Wednesday ready for talks with his hosts, as well British, Polish and German leaders on Thursday.
A third diplomat said Canada and Italy had been invited, although others were unable to confirm their presence.
Talks will centre on ongoing efforts to end the war, security assurances for Kyiv and how to boost aid for Ukraine, the sources said.
'Massive' attack on Odesa injures three
A bit more on that apparent Russian attack on Odesa now.
"The enemy massively attacked Odesa and the region with attack drones," the local regional governor has said.
"There is damage to civilian infrastructure, including a residential high-rise, a shopping centre and shops," Oleg Kiper said.
Three people were injured, including a young girl, he added.
"As a result of the Russian attack, powerful fires broke out in three locations."
He also urged residents to stay indoors as it was not clear if the attack was over.
Why did the PM visit a nuclear-armed submarine?
As we've been reporting, the prime minister today visited Britain's next generation of nuclear submarine.
While being reminded about British nuclear strength, Russian President Vladimir Putin will also doubtless take note of a potential weakness, Sky security and defence editorDeborah Haynes explains in this video...
'Odesa is on fire'
The Ukrainian city of Odesa is under attack from Russian drones, the head of the office of the president has said.
It's not clear how many people are hurt at present.
Andriy Yermak said: "Odesa is on fire.
"Russian drones are hitting civilian targets in the city, there arecasualties."
Who is attending the military chiefs meeting?
Today, the UK is hosting military officials from at least 26 countries today as Sir Keir Starmer hopes to move his "coalition of the willing" into an "operational phase".
Discussions will be focused on how nations involved could potentially form a peacekeeping force - what that may look like, what logistics would be required and so on.
We've not seen a definitive list of all the countries attending, but military patches bearing flags and other identifiers have been spotted.
Those include: France, Ukraine, Germany, Poland, Canada, Denmark, Australia, Czechia, Finland, Albania, Turkey, Sweden, Norway, New Zealand, Netherlands, Romania, Portugal, Luxembourg, Latvia, Lithuania, Cyprus, Bulgaria, Belgium, Spain, Italy and Estonia.
Trump: Rare earths deal to be signed shortly
Donald Trump is speaking from the White House, unveiling another swathe of executive orders.
He first discusses a new order to increase US production of critical minerals and rare earths.
He instantly turns to Ukraine, and says: "One of the things we are doing is signing a deal, very shortly, with respect to rare earths with Ukraine which have tremendous value."
Yesterday, the White House said it had "moved on" from the deal, although sources indicated later to our US correspondent Mark Stone that that wasn't quite the case.
"And now we have moved beyond the economic minerals deal. We are at a place of peace. We're at a partial ceasefire, and we're moving towards a full ceasefire and a long-standing peace in this conflict."
White House press secretary Karoline Leavitt speaking yesterday
Trump also comments more broadly on the conflict.
"We're doing very well with regard to Ukraine and Russia," he says, referencing calls with Vladimir Putin and Volodymyr Zelenskyy.
"We would love to see that [war] come to an end and I think we're doing pretty well in that regard."
He says he believes "we'll get a deal done".
US negotiators will 'walk between Russian and Ukrainian rooms' during peace talks
A bit more on what the peace talks in Saudi Arabia will look like on Monday now...
A Ukrainian source has told Sky News how the Americans plan to handle talking to Russian and Ukrainian delegations separately.
"In general, the concept of the Americans is that they are talking with Russians and they are talking with Ukrainians simultaneously, in different rooms and would kind of walk between meetings/rooms," the source said.
"But its still not clear which kind of format of talks will be in the end.
"It's not planned that Ukrainians and Russians will havedirecttalks."
