The Ministry of Defence says there is “a serious level of inaccuracy” in leaks which claim UK special forces have been operating in Ukraine.
The claims have been widely reported after US classified military documents were allegedly leaked and published online.
A Ministry of Defence spokesperson has warned against taking allegations contained in the reported leak at “face value”.
A spokesperson said in a message posted on Twitter: “The widely reported leak of alleged classified US information has demonstrated a serious level of inaccuracy.
“Readers should be cautious about taking at face value allegations that have the potential to spread disinformation.”
Media outlets have reported that a document, dated 23 March, indicates as many as 50 UK special forces personnel have been deployed to the country alongside other western special forces.
But the document reportedly does not state where the allegedly deployed forces are located or what they are doing.
Chris Meagher, a spokesman for the Pentagon, has urged caution in “promoting or amplifying any of these documents”, adding that “it does appear that slides have been doctored”.
The documents may first have been published in a chatroom on Discord, a social media platform popular with gamers, Associated Press reported.

An unidentified chatroom user shared documents that were allegedly classified, first typing them out with their own thoughts, then, as of a few months ago, beginning to post images of papers with folds in them.
The posts appear to have gone unnoticed outside of the chat until a few weeks ago, when they began to circulate more widely on social media.
Many details shared by the person have not been independently verified and the original chatroom has been deleted.
Asked on Monday if the US government was effectively waiting for more intelligence documents to show up online, National Security Council spokesman John Kirby replied: “The truth and the honest answer to your question is: We don’t know. And is that a matter of concern to us? You’re darn right it is.”
It comes after the US defence department began investigating who is responsible for the potentially damaging leak.

From 5 April: Putin – US-Russia relations ‘in deep crisis’
The New York Times, which first reported the breach, quoted military analysts as saying the files appear to have been modified in certain parts, which could point to an attempt by Moscow to spread disinformation.
Wall Street Journal correspondent Yaroslav Trofimov said Russian propaganda channels appeared to have photoshopped at least one of the documents after the original ones were posted.
Mr Trofimov noted how there was suddenly a significant increase in the number of Ukrainian casualties and equipment losses recorded and a massive decrease in the Russian battle damage.
Ukrainian presidential official, Mykhailo Podolyak, said the leak looked like a Russian disinformation operation, saying that it contained a “very large amount of fictitious information”.
The act of stealing secret documents and leaking them either with or without modifications is a long-standing weapon of information warfare designed to undermine an opponent.
It would benefit Russia for information about Ukraine’s battle plans and Western support to be leaked online.
The classified files – including one marked “top secret” and another marked “secret” – are dated from late February and early March.
They do not reveal specific dates or details about Ukraine’s anticipated spring offensive in the east and south of the country.
But they do offer clues about the kind of military formations that Western allies are helping their Ukrainian partners build up.
The New York Times said US officials were trying to have the files taken down off the social media sites.
However, as of last Friday morning, versions of the leaks were still being widely shared.
It is raising new concerns in the global players’ union about whether the stars of the sport are being protected in hot and humid conditions.
FIFPRO has asked FIFA to allow cooling breaks every 15 minutes rather than just in the 30th minute of each half.

There’s also a request for half-time to be extended from 15 to 20 minutes to help lower the core temperature of players.
FIFPRO’s medical director, Dr Vincent Gouttebarge, said: “There are some very challenging weather conditions that we anticipated a couple of weeks ago already, that was already communicated to FIFA.
“And I think the past few weeks were confirmation of all worries that the heat conditions will play a negative role for the performance and the health of the players.”
Football has seemed focused on players and fans baking in the Middle East – but scorching summers in Europe and the US are becoming increasingly problematic for sport.

While climate change is a factor, the issue is not new and at the 1994 World Cup, players were steaming as temperatures rose in the US.
There is now more awareness of the need for mitigation measures among players and their international union.
FIFPRO feels football officials weren’t responsive when it asked for kick-off times to be moved from the fierce afternoon heat in the US for the first 32-team Club World Cup.
FIFA has to balance the needs of fans and broadcasters with welfare, with no desire to load all the matches in the same evening time slots.
Electric storms have also seen six games stopped, including a two-hour pause during a Chelsea game at the weekend.
This is the dress rehearsal for the World Cup next summer, which is mostly in the US.

The use of more indoor, air conditioned stadiums should help.
There is no prospect of moving the World Cup to winter, as Qatar had to do in 2022.
And looking further ahead to this time in 2030, there will be World Cup matches in Spain, Portugal and Morocco. The temperatures this week have been hitting 40C (104F) in some host cities.

Wildfires erupt in Italy and France amid heatwave
FIFA said in a statement to Sky News: “Heat conditions are a serious topic that affect football globally.
“At the FCWC some significant and progressive measures are being taken to protect the players from the heat. For instance, cooling breaks were implemented in 31 out of 54 matches so far.
“Discussions on how to deal with heat conditions need to take place collectively and FIFA stands ready to facilitate this dialogue, including through the Task Force on Player Welfare, and to receive constructive input from all stakeholders on how to further enhance heat management.
“In all of this, the protection of players must be at the centre.”

Who has (and hasn’t) made the England squad?
Some notable names will be missing from the England squad this year.
Goalkeeper Mary Earps announced in May that she is retiring from international football with immediate effect.
Within days, two other names, Fran Kirby and Millie Bright, also announced they would not be taking part in Euro 2025.
The departure of Bright, Earps and Kirby is a loss of three experienced players – between them they have 218 international appearances.
So who has manager Sarina Wiegman picked for the 23-person squad, and who has been snubbed?
Use our slider below to look through some of the key players, or see a list of the full England squad, here.
History-making Wales squad announced
The Welsh women’s national football team has qualified for an international tournament for the first time.
Their 23-player squad was announced by head coach Rhian Wilkinson at the summit of Yr Wyddfa (Snowdon) on Thursday morning.

Midfielder Angharad James captains the side, and is one of four players to have played over 100 times alongside fellow Wales veterans Jess Fishlock, Hayley Ladd and Sophie Ingle, who also made the cut.
Ingle hasn’t featured for club or country since suffering an ACL injury during a pre-season friendly for Chelsea last September.
The 33-year-old returned to full training at the beginning of the month and her inclusion comes as a significant boost ahead of Wales’ first major tournament.
Fishlock, Wales’ record appearance holder and goalscorer, will hope to add to her 47 international goals as she leads the line.
The side beat the Republic of Ireland 2-1 in a play-off match to secure their spot in the Euros.

Wales head coach Rhian Wilkinson said after the match: “This team found a way. They never broke for each other, they stayed strong. I’ve never been prouder of a team.
“This team stands on the shoulders of giants [the pioneering female footballers] who came before, and now they’ve proven how good they are.”
Similarly to the World Cup, teams in the Euros are split into four groups.
The top two teams in each group will progress to the knockout stage, where games will be decided by extra-time and penalties if needed.
The knockout stage pits the winners of the group against the runners-up, meaning Germany, Poland, Denmark or Sweden could lie in wait for England and Wales in the last eight.
Group A: Switzerland, Norway, Iceland, Finland
Group B: Spain, Portugal, Belgium, Italy
Group C: Germany, Poland, Denmark, Sweden
Group D: France, England, Wales, Netherlands
When are England and Wales playing?
The Lionesses start their bid for the Euros title on 5 July when they take on France. The game will take place in Zurich at 8pm UK time.
Wales kick off their campaign earlier the same day, against the Netherlands. That game starts at 5pm UK time in Lucerne.
The two nations will be the last teams in Group D to face each other.
Their showdown will be held in the city of St Gallen, on Sunday 13 July. Kick-off is at 8pm UK time.
Can England win the Euros again?
The Lionesses lifted the Euros trophy in front of a home crowd in 2022, after beating Germany 2-1.
Chloe Kelly delivered the deciding goal in extra time, but can the team do it all again?

Can England win the Euros again?
Lucy Bronze admitted to Sky News that the team faces “one of the hardest” groups going into the tournament, but added: “We know on any given day, when we play at our best we can beat any team in the world.”
The right-back said: “We have got one of the most talented squads going into the Euros… I wouldn’t want to be a defender on the other team going against some of our players.
“We know it is going to be difficult, there are maybe a handful of teams that are capable of winning it, and we are definitely one of them.”

“I am excited to see what we are capable of this summer.”
How to watch the Euros 2025

A flight in Australia was delayed for two hours after a stowaway snake was found in the plane’s cargo hold.
The reptile was found as passengers were boarding Virgin Australia Flight VA337 at Melbourne Airport bound for Brisbane.
Snake catcher Mark Pelley said he thought it could be venomous when he approached it in the darkened hold.

But it turned out to be a harmless 60cm green tree snake.
“It wasn’t until after I caught the snake that I realised that it wasn’t venomous. Until that point, it looked very dangerous to me,” Mr Pelley said.
He said when he entered the cargo hold, the snake was half hidden behind a panel and he feared it could flee deeper into the plane.
“I had one chance to grab it, and if it escaped past me it would have gone into the panels, and then that would have been extremely hard to catch,” he told Sky News.
“Snakes are very fast-moving, thin and agile,” he added.
Mr Pelley said he told an aircraft engineer and airline staff they would have to evacuate the aircraft if the snake disappeared inside the plane.
“I said to them if I don’t get this in one shot, it’s going to sneak through the panels and you’re going to have to evacuate the plane because at that stage I did not know what kind of snake it was,” he explained in a separate interview.
“But thankfully, I got it on the first try and captured it,” he added. “If I didn’t get it that first time, the engineers and I would be pulling apart a [Boeing] 737 looking for a snake still right now.”
