Speaking at a board meeting of the FSB - Russia's security service - Russian President Vladimir Putin today made no substantial reference to the war he launched on Ukraine four years ago.

Instead he referred to the unsubstantiated claims made by Russia's foreign intelligence service that the UK and France were plotting to arm Ukraine with a nuclear bomb. "[The UK and France] probably understand how any attack on Russia using a nuclear element could end," Putin warned.

He also accused Kyiv of being behind what he called a "terrorist attack" near Savyolovsky station in Moscow on Monday, which killed a traffic police officer and injured two others. Putin said a person was "recruited" over the internet then made to carry an explosive device which was detonated remotely. (Russian officials had previously said the blast was a suicide attack.)

Putin urged FSB officers to "intensify the fight against terrorism" and stated that Kyiv had placed its bet on "terrorism" as it had not been able to "defeat Russia on the battlefield".

The Russian president also warned - without sharing evidence - that sabotage attempts on pipelines in the Black Sea were forthcoming, and accused Kyiv's Western partners of preventing a settlement between Kyiv and Moscow from being reached during peace talks.

Four years of war have brought significant casualties on both sides - but verifying the exact figures can be challenging.

Last month, President Volodymyr Zelensky told French broadcaster France 2 that "officially" 55,000 Ukrainians had been killed on the battlefield. In addition, a "large number of people" are considered officially missing, he said, though he did not give an exact figure.

Based on estimates from sources including the UA Losses website, which the BBC has cross-referenced, the number of Ukrainians killed could be as high as 200,000.

On the Russian side, the BBC has now identified the names of over 186,000 Russian soldiers killed in the war. The true death toll is generally accepted to be much higher, as many deaths on the battlefield are not recorded.

Military experts believe this analysis might represent 45-65% of the total, putting the potential number of Russian deaths at between 286,000 and 413,500.

Let's take a closer look at where the land lies as we enter the fifth year of war between Russia and Ukraine.

Territory

• Russia took about 4,700 sq km (1,800 sq miles) of territory in 2025 - an area about twice the size of the city of Moscow - according to analysts at the US-based Institute for the Study of War (ISW)
• Russian forces have been moving mile by mile through the Donbas region, trying to gain full control of the area along with two other regions, Zaporizhzhia and Kherson
• But it has never had these regions under full control - and in some front line areas, Russian forces appear to have been forced to retreat
• It has also come at significant cost in terms of casualties - more on that in our next post

Peace negotiations

• Despite multiple rounds of peace talks, there are still key hurdles to overcome
• An agreement on territory remains elusive, with Russia still seeking full control of the eastern Donbas, a non-starter for Ukraine
• US President Trump has been driving the talks but has previously been accused of being too aligned with Russia
• The most recent round of negotiations in Geneva concluded without a breakthrough on 18 February

Ukrainians don't want war, but no-one is telling me they should sue for peace eitherpublished at 13:17 GMT

It has been a long, hard and deadly four years. Ukraine is under pressure from Trump’s America to give up strategic land that Russia has failed to capture despite sacrificing thousands of its troops.

President Zelensky told me at the weekend that he would not be giving up land. President Putin shows no sign of dropping his maximalist demands. Putin has made clear his belief that Ukraine should be under Russia’s control.

The foreman of the men salvaging steel from the ruins of a destroyed Ukrainian power station told me Russia was attacking sources of power, heat and light for civilians to bring Ukraine to its knees. His tone strongly suggested that he was not prepared to accept that, like so many others here.

I’ve found no-one telling me that Ukraine needs to sue for peace. Their history with Russia is long and bloody and they don’t want to return to Moscow’s control.

That doesn’t mean they want more war. But they don’t believe that a sacrifice of land for a ceasefire would satisfy Putin’s territorial ambitions.

The Russia-Ukraine war has upended assumptions about European security and the safety of the future. The full-scale invasion was an early warning that the world was changing. Nothing in the last four years has suggested it is any safer, and the war here and its global consequences are a central reason for that.

Today Ukraine and its President Volodymyr Zelensky are being showered with support by European allies in the 'coalition of the willing'. It’s a big change from the first day of the full scale invasion, four years ago exactly. Then, they expressed outrage that President Putin had ordered his men to invade - but their military analysis was that Ukraine would lose within a few weeks. That was Putin’s assumption too.

They were, of course, wrong.

I was in Kyiv during the time when Russian forces were at the edge of the city. At the height of a civilian exodus 50,000 people a day were boarding trains at the main railway station to head west, away from the Russians.

I had read many assessments of Russian strength and Ukraine’s relative weakness, and every morning I was expecting some kind of Russian breakthrough. Tank obstacles and sandbagged strongpoints were erected at road junctions and checkpoints with every expectation that they would be needed.

It took a few weeks to realise that not only were the Russians being held, they were losing the battle for Kyiv. On 29 March 2022, Russia announced it was pulling its forces back from Kyiv.

After that, Ukraine was taken much more seriously by its Western allies.

If you’re just joining us, we’ve been following tributes from Ukrainians and European allies that are marking the fourth anniversary of Russia’s invasion of Ukraine.

We’ve heard from Ukraine’s President Volodymyr Zelensky, who’s urged Donald Trump to “stay on our side”, and called for more support from the EU to restore key infrastructure. Zelensky also pushed for a date to join the EU, warning that without one Russia would seek to block the move.

European leaders are in the Ukrainian capital Kyiv, attending memorial events and visiting a power plant badly damaged by Russian air strikes. They then joined UK PM Keir Starmer and French PM Emmanuel Macron, who virtually hosted a meeting of the 'coalition of the willing'.

That came after Starmer announced the UK's largest package of sanctions against Russia since the early months of the war in 2022.

But Kremlin spokesperson Dmitry Peskov said the“full goals” of the war had not yet been achieved. Moscow is demanding that eastern regions of Ukraine - the Donbas - are handed over, an unacceptable condition for Kyiv.

Our diplomatic correspondent Paul Adams has been speaking to those paying tribute across Ukraine, including hearing from a Ukrainian father whose son died in the conflict in 2023 and who says “we need to keep fighting”.

We'll hear more about the impact on the ground at 16:30 GMT, in the BBC's special programme, War in Ukraine: What Happens Next?

Since the publication of our previous post on Russian claims that Britain and France are planning to arm Ukraine with a nuclear weapon, we have heard a rebuttal from Downing Street.

The PM's official spokesperson describes the claims as "a clear attempt by Vladimir Putin to distract" from Russia's actions in Ukraine and there are "no truth" to them.

He adds that the "package of action on military, humanitarian, reconstruction fronts" announced today shows where the UK's support for Ukraine lies.

Laura Gozzi

Earlier today Russia's Foreign Intelligence Service (SVR) released an entirely unsubstantiated statement accusing the UK and France of plotting to arm Ukraine with a nuclear weapon or a "dirty bomb".

The SVR said Paris and London realised that the current situation in Ukraine "leaves no chance of achieving their much-desired victory over Russia at the hands of the Ukrainian army", and that they were therefore facilitating Kyiv's acquisition of nuclear weapons.

Earlier today Kremlin spokesman Dmitry Peskov said Russia would "take into account" the claims during future negotiations on a Ukraine peace settlement.

The SVR's accusations are completely unfounded, and the agency has provided no documents or leaks to support it. Russian government-affiliated agencies have a history of sharing wild claims of this ilk. Neither the UK nor France have commented.

BBC Monitoring

Russian state TV channels made no mention on 24 February of the fourth anniversary of Moscow’s full-scale invasion of Ukraine. Prime time news bulletins the previous evening were also silent on the date.

Instead, coverage focused on reported battlefield advances and events marking Defender of the Fatherland Day, which commemorates Russian military achievements.

In one broadcast, Channel One honoured what it called the “heroes of the special military operation”.

Some officials addressed the human cost online. Belgorod Governor Vyacheslav Gladkov said, external “hundreds of civilians” had been killed in the border region over four years, adding that the local economy had adapted to “constant shelling and threats”.

Prominent pro-war bloggers, meanwhile, struck a defiant tone, portraying the conflict as an existential struggle and urging continued unity and support for the armed forces.

In his video address this morning, President Volodymyr Zelensky listed the names of places associated with the horrors of the past four years. Top of the list was Bucha.

This is where the brutality of Russia’s all-out invasion was first, shockingly, revealed.

Captured in the first days of the invasion, after Russian airborne troops landed at nearby airport, Bucha was occupied for several weeks, before being pushed back in late March.

Evidence of atrocities quickly emerged. The bodies of civilians lying where they were shot in the streets. A mass grave containing the bodies of scores of people, unearthed in front of the world’s cameras.

Suddenly Bucha was notorious.

This morning, under grey skies and recent winter snow melting all around, people gathered at a military cemetery to commemorate the fallen; not only those who died in those early weeks but a host of others who have been killed since, in front-line battles hundreds of miles away.

Orthodox priests led prayers and Ukraine’s national anthem rang out, but it was a mostly silent affair, as relatives laid flowers, stood in quiet contemplation and left.

Serhii Zavadsky, 49, was here to pay respects to his oldest son, Oleksiy, who died in 2023 during the siege of Bakhmut, weeks before he was due to be married.

“We need to keep fighting,” Serhii told us. “We don’t have any choice."

“I believe in our victory, because truth is on our side. If I could, I would wipe Russia from the face of the earth.”

Keir Starmer says Ukraine's allies need to "shift the narrative" away from the perception that Russia is winning the conflict.

“We’ve got to shift the narrative. Whatever Putin tells himself and his people, Russia is not winning, and we must shift the narrative into that place with greater force and determination," he says.

During his call with Zelensky and European leaders, Starmer says that Russia has suffered "half a million casualties in the last year, to gain and occupy less than 1% extra of Ukrainian territory".

The Russian economy is also suffering, he says. But he adds that allies need to "increase pressure on Russia and its war economy", before referencing the new sanctions announced by the UK today.

We're now seeing footage of a "coalition of the willing" meeting, where Prime Minister Keir Starmer is speaking to Ukraine's Volodymyr Zelensky - as well as other leaders - via video.

We'll bring you the key lines as we get them, and you can watch live at the top of the page.

The Kremlin has told the BBC that both Russia and Russians have “changed considerably” in the four years since Vladimir Putin launched his “special military operation”.

“It’s been a very important four years in the history of our country: it will remain forever in people’s memories,” Kremlin spokesman Dmitry Peskov said on the day the war entered its fifth year.

He said he believed the war had triggered a “phenomenal consolidation” in Russian society, particularly around the president, and that Russians now better understood their roots.

Although few people in Russia publicly criticise the war or President Putin, a growing weariness with the consequences of the war and its effect on people’s lives, including high inflation, is palpable in the country.

Peskov did not answer whether the Kremlin believed Russia would still be fighting in Ukraine four years on. Nor could he confirm when or where the next round of trilateral Russia-Ukraine-US talks would take place.

He once again accused the UK of interfering in attempts at a peace deal between Russia and Ukraine at an early stage in the war, and said the war had grown into a far bigger conflict due to the “direct involvement of countries in western Europe and the United States”.

Kremlin spokesman Dmitry Peskov says the "full goals of the special operation" not yet been achieved, which is why the conflict continues.

Peskov made the comments during a regular scheduled call with journalists, during which he referenced Moscow's main talking points around the war, including that Russia was open to resolving the conflict diplomatically.

Moscow is demanding eastern regions of Ukraine - known as the Donbas - are handed over, an unacceptable condition for Kyiv. Multiple rounds of US-brokered talks over the last few months seem to have reached a stalemate largely due this demand.

Peskov also said that the past four years had been "very important" for Russia, and they would "forever remain in people's memories".

Since 2022 millions of Russian lives have been lost or upended by the war and its sprawling consequences - from high inflation to mass emigration.

In the UK, Prime Minister Keir Starmer has promised during a cabinet meeting to support Ukraine "for as long as it takes" and said that Vladimir Putin is "standing in the way" of a peace deal to end the war in Ukraine.

It comes as the UK announced what is says is the largest package of sanctions against Russia since the early months of the war in 2022, targeting what the Foreign Office says are critical oil revenues.

The government says it is sanctioning 175 companies in the "2Rivers" oil network, one of the largest shadow fleet operators globally and a major trader of Russian crude oil.

The government says the sanctions will also clamp down on nine Russian banks, civil nuclear energy companies and companies supplying components and technology for Russian drones.

But critics have long claimed that Western sanctions are less effective than first hoped.

As Ukrainians gathered to observe a minute's silence this morning, world leaders were also in Kyiv to commemorate the conflict entering its fifth year.

President of the EU Commission, Ursula von der Leyen, said she was among leaders remembering the "fallen heroes of Ukraine".

Volodymyr Zelensky is pushing for Ukraine to be given a date to join the EU, warning that without one Russia could seek to block the move.

"This is not just a wish, it's a clear understanding of how Putin will act," he said in a virtual address to the European Parliament this morning.

"If there's no date, if there's no such guarantee, he will find a way to block Ukraine [...] by dividing you, by dividing Europe. We must protect ourselves from this."

In the same speech he also pushed for further sanctions, saying "there must be no place in the free word for Russian oil, for Russian tankers, Russian banks... or for any Russian war criminals."

Footage of President Volodymyr Zelensky's top-secret bunker has been made public for the first time. It appears at the start of his address to the nation made to mark the fourth anniversary of the full-scale invasion by Russia.

The video shows a long windowless corridor with a sign saying "The Ukrainian President's Office", then an Orthodox icon on a wall with a depiction of the Ukrainian national symbol, the Tryzub, underneath.

"This office – this small room in the bunker on Bankova Street – this is where I held my first conversations with world leaders at the start of the war. Here I spoke with President Biden, and it was right here that I heard: Volodymyr, there is a threat. You need to leave Ukraine urgently. We are ready to help with that. And here I replied that I need ammunition, not a ride," Zelensky said.

Bankova Street is located in the heart of the government quarter in the Ukrainian capital Kyiv, and has been the site of presidential offices since independence in 1991.

While European leaders gather in Kyiv, Slovakian Prime Minister Robert Fico has ordered his country's state-controlled electricity distributor to refuse requests for emergency assistance from Ukraine as a spat over Russian oil supplies escalates.

Slovakia and Hungary - the two most pro-Russian countries in the EU - accuse Ukraine of deliberately holding back Russian oil shipments via the Soviet-era Druzhba pipeline, which pumps Russian crude into Central Europe via Ukraine.

Kyiv says the pipeline was damaged in a Russian drone attack in January and is still not ready to resume supply; Bratislava and Budapest dispute this, and accuse the Ukrainians of blackmail.

In a video message, Fico said he took the decision after President Zelensky informed him he would be unavailable to discuss the matter until Wednesday at the earliest.

"The likely halt to emergency electricity supply from Slovakia will in no way affect the situation in Ukraine's unified power system," Ukrenergo said.

Ukraine's energy monopoly Ukrenergo said it had last sought emergency supplies from Slovakia more than a month ago and in small volumes.

Landlocked Slovakia and Hungary are the only EU countries which still import Russian oil after receiving a temporary exemption from an EU ban.

However, other landlocked countries such as the Czech Republic point out they have successfully ended their reliance on Russia.
