In the courtyard of a farmhouse now home to soldiers of the Ukrainian army’s 47th mechanised brigade, I’m introduced to a weary-looking unit by their commander Captain Oleksandr “Sasha” Shyrshyn.
We are about 10km from the border with Russia, and beyond it lies the Kursk region Ukraine invaded in the summer – and where this battalion is now fighting.
The 47th is a crack fighting assault unit.
They’ve been brought to this area from the fierce battles in the country’s eastern Donbas region to bolster Ukrainian forces already here.

Captain Shyrshyn explains that among the many shortages the military has to deal with, the lack of infantry is becoming a critical problem.
Sasha is just 30 years old, but he is worldly-wise. He used to run an organisation helping children in the country’s east before donning his uniform and going to war.
He is famous in Ukraine and is regarded as one of the country’s top field commanders, who isn’t afraid to express his views on the war and how it’s being waged.
His nom de guerre is ‘Genius’, a nickname given to him by his men.

‘Don’t worry, it’s not a minefield’
Sasha invited me to see one of the American Bradley fighting vehicles his unit uses.
We walk down a muddy lane before he says it’s best to go cross-country.
“We can go that way, don’t worry it’s not a minefield,” he jokes.
He leads us across a muddy field and into a forest where the vehicle is hidden from Russian surveillance drones that try to hunt both American vehicles and commanders.
Sasha shows me a picture of the house they had been staying in only days before – it was now completely destroyed after a missile strike.
Fortunately, neither he, nor any of his men, were there at the time.
“They target commanders,” he says with a smirk.

It takes me a moment or two to realise we are only a few steps away from the Bradley, dug in and well hidden beneath the trees.

Sasha tells me the Bradley is the finest vehicle he has ever used.
A vehicle so good, he says, it’s keeping the Ukrainian army going in the face of Russia’s overwhelming numbers of soldiers.
He explains: “Almost all our work on the battlefield is cooperation infantry with the Bradley. So we use it for evacuations, for moving people from one place to another, as well as for fire-covering.
“This vehicle is very safe and has very good characteristics.”

Billions of dollars in military aid has been given to Ukraine by the United States, and this vehicle is one of the most valuable assets the US has provided.
Ukraine is running low on men to fight, and the weaponry it has is not enough, especially if it can’t fire long-range missiles into Russia itself – which it is currently not allowed to do.

Sasha says: “We have a lack of weapons, we have a lack of artillery, we have a lack of infantry, and as the world doesn’t care about justice, and they don’t want to finish the war by our win, they are afraid of Russia.
“I’m sorry but they’re scared, they’re scared, and it’s not the right way.”
Like pretty much everyone in Ukraine, Sasha is waiting to see what the US election result will mean for his country.
He is sceptical about a deal with Russia.
“Our enemy only understands the language of power. And you cannot finish the war in 24 hours, or during the year without hard decisions, without a fight, so it’s impossible. It’s just talking without results,” he tells me.

These men expect the fierce battles inside Kursk to intensify in the coming days.
Indeed, alongside the main supply route into Kursk, workers are already building new defensive positions – unfurling miles of razor wire and digging bunkers for the Ukrainian army if it finds itself in retreat.

Sasha and his men are realistic about support fatigue from the outside world but will keep fighting to the last if they have to.
“I understand this is only our problem, it’s only our issue, and we have to fight this battle, like we have to defend ourselves, it’s our responsibility,” Sasha said.
But he points out everyone should realise just how critical this moment in time is.
“If we look at it widely, we have to understand that us losing will be not only our problem, but it will be for all the world.”
Stuart Ramsay reports from northeastern Ukraine with camera operator Toby Nash, and producers Dominique Van Heerden, Azad Safarov, and Nick Davenport.
At least 20 people have been killed and dozens more injured after an Israeli airstrike targeting a school in Gaza, health authorities have said.
Reuters news agency reported the number of dead, citing medics, with the school in the Daraj neighbourhood having been used to shelter displaced people who had fled previous bombardments.
Medical and civil defence sources on the ground confirmed women and children were among the casualties, with several charred bodies arriving at al Shifa and al Ahli hospitals.
The scene inside the school has been described as horrific, with more victims feared trapped under the rubble.

Donald Trump has threatened Russia with more sanctions after a series of deadly strikes across Ukraine, as he said of Vladimir Putin: “What the hell happened to him?”
Speaking to reporters at an airport in New Jersey ahead of a flight back to Washington, Mr Trump said: “I’m not happy with Putin. I don’t know what’s wrong with him.”
“He’s killing a lot of people,” he added. “I’m not happy about that.”
Mr Trump – who said he’s “always gotten along with” Mr Putin – told reporters he would consider more sanctions against Moscow.
“He’s sending rockets into cities and killing people, and I don’t like it at all,” he said.
Ukraine said the barrage of strikes overnight into Sunday was the biggest aerial attack of the war so far, with 367 drones and missiles fired by Russian forces.
It came despite Mr Trump repeatedly talking up the chances of a peace agreement. He even spoke to Mr Putin on the phone for two hours last week.

Hundreds of drones fired at Ukraine
‘Shameful’ attacks
Volodymyr Zelenskyy has said Ukraine is ready to sign a ceasefire deal, and suggested Russia isn’t serious about signing one.
In a statement after the latest attacks on his country, he urged the US and other national leaders to increase the pressure on Mr Putin, saying silence “only encourages” him.
Mr Trump’s envoy for the country, Keith Kellogg, later demanded a ceasefire, describing the Russian attacks as “shameful”.
Three children were among those killed in the attacks, explosions shaking the cities of Kyiv, Odesa, and Mykolaiv.

Before the onslaught, Russia said it had faced a Ukrainian drone attack on Sunday. It said around 100 were intercepted and destroyed near Moscow and in central and southern regions.
The violence has escalated despite Russia and Ukraine completing the exchange of 1,000 prisoners each over the past three days.
Donald Trump says he will delay the imposition of 50% tariffs on goods entering the United States from the European Union until July, as the two sides attempt to negotiate a trade deal.
It comes after the president of the European Commission, Ursula von der Leyen, said in a post on social media site X that she had spoken to Mr Trump and expressed that they needed until 9 July to “reach a good deal”.
But Mr Trump has now said that date has been put back to 9 July to allow more time for negotiations with the 27-member bloc, with the phone call appearing to smooth over tensions for now at least.
Speaking on Sunday before boarding Air Force One for Washington DC, Mr Trump told reporters that he had spoken to Ms Von der Leyen and she “wants to get down to serious negotiations” and she vowed to “rapidly get together and see if we can work something out”.
The US president, in comments on his Truth Social platform, had reignited fears last Friday of a trade war between the two powers when he said talks were “going nowhere” and the bloc was “very difficult to deal with”.
Mr Trump told the media in Morristown, New Jersey, on Sunday that Ms Von der Leyen “just called me… and she asked for an extension in the June 1st date. And she said she wants to get down to serious negotiation”.

“We had a very nice call and I agreed to move it. I believe July 9th would be the date. That was the date she requested. She said we will rapidly get together and see if we can work something out,” the US president added.

12 May: US and China reach agreement on tariffs
Much of his most incendiary rhetoric on trade has been directed at Brussels, though, even going as far as to claim the EU was created to rip the US off.
Responding to his 50% tariff threat, EU trade chief Maros Sefcovic said: “EU-US trade is unmatched and must be guided by mutual respect, not threats.
