Ukraine’s counteroffensive is now into its fourth month. Kyiv’s forces, bolstered by Western tanks and weapons, are putting pressure on Russian positions but have yet to achieve a major breakthrough.
But all across Ukraine, there is a sense that things could change very quickly. A section of defences could collapse, and fortunes could turn.
Sky News spoke to military expert Sean Bell about the different parts of the frontline and how each could be a flashpoint, from crossing the Dnipro in the west to the push to liberate Bakhmut in the east.
We’ve zeroed in on five locations and ask, is this where the war could be decided?
Can Ukraine break through in Zaporizhzhia?
The southern battle-zone in the Zaporizhzhia region is perhaps the most talked about part of the war at the moment.
Bell says this so-called land bridge between Crimea and the Donbas is “the least hard place” for Ukrainians to liberate the most territory.

The Surovikin line, named after a Russian general, extends through the area, a triple layer of defences comprising an anti-tank ditch, dragons’ teeth obstacles and then defensive positions in trenches.

If Ukrainian forces are able to pierce through in Zaporizhzhia and reach the coast of the Sea of Azov – or at least get close enough to hit the remaining territory with artillery – it would effectively cut Russian forces in half.
“If they can break through all those defences then suddenly there could be a rout of Russian forces in that land bridge,” Bell says.
There has been evidence so far during the counteroffensive that Ukraine has been keeping much of its Western tanks and best-trained troops in reserve, waiting for a breakthrough somewhere along the line.
Now, it seems, some of these tanks are being sent in to fight in the battle for Zaporizhzhia.
“You are never sure what will be the chink that will break the dam, you will never know until the crack emerges and the floodgates open.
“The question is whether the Ukrainians then have the stamina and the morale and the equipment to take advantage of it.”
Encircling a ruined city – and pinning down Russian forces
The city held out for so long. Waves and waves of Russian soldiers – many of them conscripts and former prisoners – were sent against Ukrainian defences and again and again Bakhmut held.
It was a controversial decision to keep defending the city, and there were many in the West who argued it was a mistake, but in the end it allowed Ukraine to inflict huge casualties on Russia and allow Kyiv time to get hold of Western tanks.
Russian forces, in particular Wagner Group mercenaries who are no longer involved, took the city at great cost.

Bakhmut does not exist as a city in the way it did before. Months of constant shelling by Russian forces have raised it to the ground.
Now, Ukraine is gaining ground around it. Could Bakhmut be liberated?
Bell says: “Bakhmut is one of those iconic places and Russia made a big thing of taking it, lost tens of thousands of lives taking it and will not want to lose it again.
“Most of the reports are the Ukrainian progress rather than Russian, but it doesn’t feel like there’s any momentum at the moment.
“Ukrainian pressure there is all designed to fix Russian forces in place.”
Is Russia pushing back in Kharkiv?
One of the main efforts of Russian forces – apart from holding back Ukrainian advances – is trying to take territory in the northeast, near Kharkiv.
Not only did they buy valuable breathing space for the ‘Hero City’, they liberated swathes of territory, including Kupyansk and Izium.
Now Russian troops are seeking to reverse some of those gains.
“The lines of communication there are very short for the Russian forces,” Bell says.
This is because of how close things are to the Russian border. Unlike in other parts of Ukraine, it’s much easier for Russia to resupply and communicate with its troops in the Kharkiv region.
In recent weeks they have claimed to have made advances, and fighting has been fierce and bloody.
Bell adds: “Russia has not been effective at conducting offensive operations since the start of the war – and that was when they had mercenary support with the Wagner Group.
“So it’s no great surprise that the Russian military are struggling to make progress.”
Crossing the Dnipro while Russia is busy elsewhere
One of the least talked about areas of the frontline is the River Dnipro, near the city of Kherson.
When Ukrainian forces swept through the region and liberated the city last year, the water became the new boundary between them and Russian forces.

“By blowing the Kakhovka dam that basically said ‘right Ukraine you are not going to be able to cross the Dnipro and we are going to leave it relatively unprotected’.”
That may have been true a few months ago, but the land is starting to dry out, presenting an opportunity for Ukraine.
“It’s a lot more accessible now and almost certainly isn’t the Russians’ main focus,” Bell says.
“It leaves them vulnerable down that flank.”
There are even reports that Ukraine has managed to land troops on the other side of the Dnipro.
But while that is progress for Kyiv, it’s not the same as establishing a beachhead from which they can deploy tanks and heavy weapons.
Bell compared it to D-Day, when the Allies managed to establish control over a chunk of French beach in June 1944 and held it until they could get armour on the ground and push outwards.
But he added that the more Ukraine puts pressure on Russian forces there, the more Kremlin commanders will have to reckon with a difficult choice: weaken their forces elsewhere to shore up the Dnipro, or risk a breakthrough across the water…
Drones, explosives and raids on Crimea
While it’s not on the frontline, Ukraine has certainly brought the war to Crimea in recent months.
It has been in Russian hands since it was annexed in 2014 but Volodymyr Zelenskyy has vowed to return it to Ukraine.

Still, it’s very heavily fortified and will be very difficult to capture by force. Indeed, in the Second World War the Axis forces led by Nazi Germany lost 30,000 men in pursuit of Crimea.
So why is Ukraine attacking it? Because putting aside the prospect of seizing the territory, it helps their forces elsewhere.
Bell says “Ukraine has made clear its intent to take it, and what that does is it forces Russia to keep forces back to protect it.”
Russia might have 150,000 soldiers in Ukraine, but if it puts them all on the frontline then there is no one to defend Crimea if Kyiv’s forces make a breakthrough.
“The more that Ukraine threatens Crimea, the more Russia has to protect it and take its forces away from the frontline.”
The IDF has admitted to mistakenly identifying a convoy of aid workers as a threat – following the emergence of a video which proved their ambulances were clearly marked when Israeli troops opened fire on them.
The bodies of 15 aid workers – including eight medics working for the Palestine Red Crescent Society (PRCS) – were found in a “mass grave” after the incident, according to the head of the UN Office for Coordination of Humanitarian Affairs Jonathan Whittall.
The Israeli military originally claimed an investigation found the vehicles did not have any headlights or emergency signals and were therefore targeted as they looked “suspicious”.
But video footage obtained by the PRCS, and verified by Sky News, showed the ambulances and a fire vehicle clearly marked with flashing red lights.
In a briefing from the IDF, they said the ambulances arrived in the Tel Sultan neighbourhood in Rafah shortly after a Hamas police vehicle drove through.

An IDF surveillance aircraft was watching the movement of the ambulances and notified troops on the ground. The IDF said it will not be releasing that footage.
When the ambulances arrived, the soldiers opened fire, thinking the medics were a threat, according to the IDF.
The soldiers were surprised by the convoy stopping on the road and several people getting out quickly and running, the IDF claimed, adding the soldiers were unaware the suspects were in fact unarmed medics.
An Israeli military official would not say how far away troops were when they fired on the vehicles.
The IDF acknowledged that its statement claiming that the ambulances had their lights off was incorrect, and was based on the testimony from the soldiers in the incident.
The newly emerged video footage showed that the ambulances were clearly identifiable and had their lights on, the IDF said.
The IDF added that there will be a re-investigation to look into this discrepancy.

Addressing the fact the aid workers’ bodies were buried in a mass grave, the IDF said in its briefing this is an approved and regular practice to prevent wild dogs and other animals from eating the corpses.
The IDF could not explain why the ambulances were also buried.
The IDF said six of the 15 people killed were linked to Hamas, but revealed no detail to support the claim.

Bodies of aid workers found in Gaza
The newly emerged footage of the incident was discovered on a phone belonging to one of the workers who was killed, PRCS president Dr Younis Al Khatib said.
“His phone was found with his body and he recorded the whole event,” he said. “His last words before being shot, ‘Forgive me, mom. I just wanted to help people. I wanted to save lives’.”
Sky News used an aftermath video and satellite imagery to verify the location and timing of the newly emerged footage of the incident.

Aid worker attacks increasing
It was filmed on 23 March north of Rafah and shows a convoy of marked ambulances and a fire-fighting vehicle travelling south along a road towards the city centre. All the vehicles visible in the convoy have their flashing lights on.
The footage was filmed early in the morning, with a satellite image seen by Sky News taken at 9.48am local time on the same day showing a group of vehicles bunched together off the road.
Ukrainian President Volodymyr Zelenskyy has hit out at the US over its “weak” response to lethal Russian attacks on his hometown on Friday.
President Zelenskyy posted a lengthy and emotional statement on X about Russia’s strikes on Kryvyi Rih, which killed 19 people.
Meanwhile Ukrainian drones hit an explosives factory in Russia’s Samara region in an overnight strike, a member of Ukraine’s SBU security service told Reuters.
In his post, President Zelenskyy accused the United States of being “afraid” to name-check Russia in its comment on the attack.
“Unfortunately, the reaction of the American Embassy is unpleasantly surprising: such a strong country, such a strong people – and such a weak reaction,” he wrote on X.
“They are even afraid to say the word “Russian” when talking about the missile that killed children.”
America’s ambassador to Ukraine Bridget Brink had written on X: “Horrified that tonight a ballistic missile struck near a playground and restaurant in Kryvyi Rih.
“More than 50 people injured and 16 killed, including 6 children. This is why the war must end.”

Strike on Zelenskyy’s home city
President Zelenskyy went on in his post to say: “Yes, the war must end. But in order to end it, we must not be afraid to call a spade a spade.
“We must not be afraid to put pressure on the only one who continues this war and ignores all the world’s proposals to end it. We must put pressure on Russia, which chooses to kill children instead of a ceasefire.”
Grandmother ‘burned to death in her home’
Oleksandr Vilkul, head of the city’s defense council, said the missile attack, followed by a drone attack, had killed 19 people, including nine children.
“The Iskander-M missile strike with cluster munitions at the children’s playground in the residential area, to make the shrapnel fly further apart, killed 18 people.
“One grandmother was burnt to death in her house after Shahed’s direct hit.”
Russia’s defence ministry said it had struck a military gathering in a restaurant – an assertion rebutted by the Ukrainian military as misinformation.
“The missile hit right on the street – around ordinary houses, a playground, shops, a restaurant,” President Zelenskyy wrote.
Mr Zelenskyy also detailed the child victims of the attack including “Konstantin, who will be 16 forever” and “Arina, who will also be 7 forever”.
The UK’s chief of the defence staff Sir Tony Radakin said he had met the Ukrainian leader on Friday, along with French armed forces leader General Thierry Burkhard.
“Britain and France are coming together & Europe is stepping up in a way that is real & substantial, with 200 planners from 30 nations working to strengthen Ukraine’s long term security,” Sir Tony wrote.
Global financial markets gave a clear vote of no-confidence in President Trump’s economic policy.
The damage it will do is obvious: costs for companies will rise, hitting their earnings.
The consequences will ripple throughout the global economy, with economists now raising their expectations for a recession, not only in the US, but across the world.
