The world’s first geological tomb for nuclear waste is rapidly taking shape more than 400 metres below the forests of Finland.
Batches of lethally radioactive uranium will start arriving within two years for burial in the warren of tunnels carved into the bedrock.
Other countries, including the UK, are considering plans to build their own geological disposal facilities, which should safely isolate the 260,000 tonnes of highly radioactive waste that has accumulated worldwide since the dawn of nuclear power in the 1950s.
Sky News was given rare access to the site, called Onkalo, which means “cavity” in Finnish. It is built next to three nuclear reactors on the country’s southwestern coast.
But we were taken down the 5km access road that winds through the bedrock, so deep that our ears popped.
At the bottom, further tunnels fanned out. So far five have been completed, but up to 100 could be built over the coming decades, stretching to more than 40 miles in all.
Our guide was Sanna Mustonen, a geologist and senior project manager for Posiva, the company that runs the facility.
She said the bedrock was formed almost two billion years ago and has remained intact ever since.

“The rock itself, like in the whole area of Finland, is very stable,” she said.
“We have old rock. We don’t have continental plates nearby, so we don’t have any earthquakes, seismicity, or things like that.”

‘There must be security’
Like other countries Finland stores spent nuclear fuel above ground in shielded bunkers while it seeks a long-term solution.
But Mika Pohjonen, managing director of Posiva, said it would be irresponsible to leave such dangerous waste where it could fall into the wrong hands.
He told Sky News: “If you look at history, 300 years back, how many wars have there been in Europe, for example?
“On the surface the interim storage needs active measures from humans, the building needs to be heated, the spent fuel must be cooled, there must be security around it.
“If you look a generation forward you cannot really see that that kind of arrangement would be risk-free enough.”
Various solutions to the nuclear industry’s waste problem have been suggested, including: launching it into deep space, burying it in an ocean trench and dropping it into a fissure in the Earth’s crust.
They’ve been dismissed as unfeasible, expensive or environmentally risky.

‘Safe for one million years’
Instead, Posiva will encase spent nuclear fuel in double-layered metal cannisters that will slot into holes bored in the floor of the tunnels.
To keep them dry, they will be swaddled in bentonite, an absorbent material used in cat litter.
More bentonite will be used to backfill the tunnels, which will be plugged with concrete.
When the complex is full in around a century’s time, with perhaps as many as 3,250 cannisters, it will be sealed up and all trace removed above ground.
“It will be safe for one million years,” Mr Pohjonen said.
“There may not be humans here any more because in that time there will be ice ages or [this area will be] underwater but this is designed to keep it out of the biosphere.”
Dummy cannisters are already buried in bentonite and surrounded by sensors.
Some scientists have warned water could corrode the metal, become radioactive and then rise to the surface over millennia.
But Posiva says the multiple barriers keep the waste in and water out. And if there was a leak in a highly unlikely worst-case scenario, modelling shows that by the time any water reached the surface in 10,000 years the radioactivity would have decayed so much that it would not be a threat to life.
Finland’s progress has been watched closely by other countries. Sweden has begun construction of its own deep geological disposal site. France, Switzerland and the UK are further behind.
A shortlist of four possible sites in Cumbria and Lincolnshire has been drawn up.

Bruce Cairns, chief policy adviser at the UK’s Nuclear Waste Services, was also taking a look at Onkalo while we were there.
He said responsible permanent disposal for waste is essential as the country commissions a new generation of reactors.
“We have 70 years’ worth of waste in the UK that’s already accumulated from energy production, defence and industrial processes.
“It’s not going anywhere unless we do something with it. We have to take action to make sure this is managed responsibly, not just for now but for the long term as well.”
Key to Finland’s progress has been engagement with the local community.

Locals in favour
The nearest settlement is Eurajoki, about 10 miles away.
The existing nuclear reactors were already big local employers and when the area was selected from a shortlist of disposal sites the local authority voted overwhelmingly in favour.
Vesa Lakaniemi, the town’s mayor, said: “We have had nuclear power here for 40 years.
“People know about nuclear and final [waste] disposal much more than in the areas which don’t have a nuclear power plant.
An Israeli reservist who served three tours of duty in Gaza has told Sky News in a rare on-camera interview that his unit was often ordered to shoot anyone entering areas soldiers defined as no-go zones, regardless of whether they posed a threat, a practice he says left civilians dead where they fell.
“We have a territory that we are in, and the commands are: everyone that comes inside needs to die,” he said. “If they’re inside, they’re dangerous you need to kill them. No matter who it is,” he said.
Speaking anonymously, the soldier said troops killed civilians arbitrarily. He described the rules of engagement as unclear, with orders to open fire shifting constantly depending on the commander.
The soldier is a reservist in the Israel Defence Force’s 252nd Division. He was posted twice to the Netzarim corridor; a narrow strip of land cut through central Gaza early in the war, running from the sea to the Israeli border. It was designed to split the territory and allow Israeli forces to have greater control from inside the Strip.
He said that when his unit was stationed on the edge of a civilian area, soldiers slept in a house belonging to displaced Palestinians and marked an invisible boundary around it that defined a no-go zone for Gazans.
“In one of the houses that we had been in, we had the big territory. This was the closest to the citizens’ neighbourhood, with people inside. And there’s an imaginary line that they tell us all the Gazan people know it, and that they know they are not allowed to pass it,” he said. “But how can they know?”
People who crossed into this area were most often shot, he said.

“It was like pretty much everyone that comes into the territory, and it might be like a teenager riding his bicycle,” he said.

The soldier described a prevailing belief among troops that all Gazans were terrorists, even when they were clearly unarmed civilians. This perception, he said, was not challenged and was often endorsed by commanders.
“They don’t really talk to you about civilians that may come to your place. Like I was in the Netzarim road, and they say if someone comes here, it means that he knows he shouldn’t be there, and if he still comes, it means he’s a terrorist,” he said.
“This is what they tell you. But I don’t really think it’s true. It’s just poor people, civilians that don’t really have too many choices.”
He said the rules of engagement shifted constantly, leaving civilians at the mercy of commanders’ discretion.
“They might be shot, they might be captured,” he said. “It really depends on the day, the mood of the commander.”
He recalled an occasion of a man crossing the boundary and being shot. When another man came later to the body, he too was shot.
Later the soldiers decided to capture people who approached the body. Hours after that, the order changed again, shoot everyone on sight who crosses the “imaginary line”.

At another time, his unit was positioned near the Shujaiya area of Gaza City. He described Palestinians scavenging scrap metal and solar panels from a building inside the so-called no-go zone.
“For sure, no terrorists there,” he said. “Every commander can choose for himself what he does. So it’s kind of like the Wild West. So, some commanders can really decide to do war crimes and bad things and don’t face the consequences of that.”
The soldier said many of his comrades believed there were no innocents in Gaza, citing the Hamas-led 7 October attack that killed around 1,200 people and saw 250 taken hostage. Dozens of hostages have since been freed or rescued by Israeli forces, while about 50 remain in captivity, including roughly 30 Israel believes are dead.
He recalled soldiers openly discussing the killings.
“They’d say: ‘Yeah, but these people didn’t do anything to prevent October 7, and they probably had fun when this was happening to us. So they deserve to die’.”
He added: “People don’t feel mercy for them.”
“I think a lot of them really felt like they were doing something good,” he said. “I think the core of it, that in their mind, these people aren’t innocent.”

In Israel, it is rare for soldiers to publicly criticise the IDF, which is seen as a unifying institution and a rite of passage for Jewish Israelis. Military service shapes identity and social standing, and those who speak out risk being ostracised.
The soldier said he did not want to be identified because he feared being branded a traitor or shunned by his community.
Still, he felt compelled to speak out.
“I kind of feel like I took part in something bad, and I need to counter it with something good that I do, by speaking out, because I am very troubled about what I took and still am taking part of, as a soldier and citizen in this country,” he said
“I think the war is… a very bad thing that is happening to us, and to the Palestinians, and I think it needs to be over,” he said.
He added: “I think in Israeli community, it’s very hard to criticise itself and its army. A lot of people don’t understand what they are agreeing to. They think the war needs to happen, and we need to bring the hostages back, but they don’t understand the consequences.
“I think a lot of people, if they knew exactly what’s happening, it wouldn’t go down very well for them, and they wouldn’t agree with it. I hope that by speaking of it, it can change how things are being done.”

We put the allegations of arbitrary killings in the Netzarim corridor to the Israeli military.
In a statement, the IDF said it “operates in strict accordance with its rules of engagement and international law, taking feasible precautions to mitigate civilian harm”.
“The IDF operates against military targets and objectives, and does not target civilians or civilian objects,” the statement continued.
The Israeli military added that “reports and complaints regarding the violation of international law by the IDF are transferred to the relevant authorities responsible for examining exceptional incidents that occurred during the war”.
On the specific allegations raised by the soldier interviewed, the IDF said it could not address them directly because “the necessary details were not provided to address the case mentioned in the query. Should additional information be received, it will be thoroughly examined.”
The statement also mentioned the steps the military says it takes to minimise civilian casualties, including issuing evacuation warnings and advising people to temporarily leave areas of intense fighting.
“The areas designated for evacuation in the Gaza Strip are updated as needed. The IDF continuously informs the civilian population of any changes,” it said.
An Australian mother has been found guilty of murdering her estranged husband’s parents and an aunt by serving them a beef wellington laced with poisonous mushrooms.
Erin Patterson, 50, invited her former parents-in-law, Don and Gail Patterson, both 70, and Gail Patterson’s sister, Heather Wilkinson, 66, to the fatal lunch on 29 July 2023.
The mother-of-two, from the state of Victoria in southern Australia, has also been convicted of the attempted murder of Mrs Wilkinson’s husband Reverend Ian Wilkinson.
All four fell ill after eating a meal of beef wellington, mashed potatoes and green beans at Patterson’s home in the town of Leongatha, the court was told.
Prosecutors said Patterson knowingly laced the beef pastry dish with deadly death cap mushrooms, also known as Amanita phalloides, at her home.
The guests ate their meals off four large grey dinner plates, while Patterson ate from a smaller, tan-coloured plate, the court heard.
Mrs Wilkinson and Mrs Patterson died on Friday 4 August 2023, while Mr Patterson died a day later.

Her estranged husband Simon Patterson, with whom she has two children, was also invited to the lunch and initially accepted but later declined, the trial heard.
The jury was told that prosecutors had dropped three charges that Patterson had attempted to murder her husband, who she has been separated from since 2015.
Reverend Wilkinson said that immediately after the meal, Patterson fabricated a cancer diagnosis, suggesting the lunch was put together so that she could ask them the best way to tell her children about the illness.
The trial attracted intense interest in Australia – with podcasters, journalists and documentary-makers descending on the town of Morwell, around two hours east of Melbourne, where the court hearings took place.
A sentencing date is yet to be scheduled.
What makes death cap mushrooms so lethal?
The death cap is one of the most toxic mushrooms on the planet and is involved in the majority of fatal mushroom poisonings worldwide.
The species contains three main groups of toxins: amatoxins, phallotoxins, and virotoxins.
From these, amatoxins are primarily responsible for the toxic effects in humans.
The alpha-amanitin amatoxin has been found to cause protein deficit and ultimately cell death, although other mechanisms are thought to be involved.
The liver is the main organ that fails due to the poison, but other organs are also affected, most notably the kidneys.
The effects usually begin after a short latent period and can include gastrointestinal disorders followed by jaundice, seizures, coma, and eventually, death.

Israel says its military has attacked Houthi targets at three ports and a power plant in Yemen.
Defence minister Israel Katz confirmed the strikes, saying they were carried out due to repeated attacks by the Iranian-backed rebel group on Israel.
Mr Katz said the Israeli military attacked the Galaxy Leader ship which he claimed was hijacked by the Houthis and was being used for “terrorist activities in the Red Sea”.

It came after the Israel Defense Forces (IDF) issued an evacuation warning for people at Hodeidah, Ras Issa, and Salif ports – as well as the Ras al Khatib power station, which it said is controlled by Houthi rebels.
The IDF said it would carry out airstrikes on those areas due to “military activities being carried out there”.
Afterwards, Mr Katz confirmed the strikes at the ports and power plant.
Earlier in the day, a ship was reportedly set on fire after being attacked in the Red Sea.
A private security company said the assault, off the southwest coast of Yemen, resembled that of the Houthi militant group.

From May: Israel strikes Yemen’s main airport
It was the first such incident reported in the vital shipping corridor since mid-April.
The vessel, identified as the Liberian-flagged, Greek-owned bulk carrier Magic Seas, had taken on water after being hit by sea drones, maritime security sources said. The crew later abandoned the ship.
The Houthi rebels have been launching missile and drone attacks against commercial and military ships in the region in what the group’s leadership called an effort to end Israel’s offensive against Hamas in Gaza.
Between November 2023 and January 2025, the Houthis targeted more than 100 merchant vessels with missiles and drones, sinking two of them and killing four sailors.
The Houthis paused attacks in a self-imposed ceasefire until the US launched an assault against the rebels in mid-March.
That ended weeks later and the Houthis have not attacked a vessel, though they have continued occasional missile attacks targeting Israel.
A renewed Houthi campaign against shipping could again draw in US and Western forces to the area.
The ship attack comes at a sensitive moment in the Middle East.
A possible ceasefire in the Israel-Hamas war hangs in the balance and Iran is weighing up whether to restart negotiations over its nuclear programme.
It follows American airstrikes last month, which targeted its most-sensitive atomic sites amid an Israeli war against the Islamic Republic that ended after 12 days.
How did the Houthis come to control much of Yemen?
A civil war erupted in Yemen in late 2014 when the Houthis seized Sanaa.
Worried by the growing influence of Shia Iran along its border, Saudi Arabia led a Western-backed coalition in March 2015, which intervened in support of the Saudi-backed government.
The Houthis established control over much of the north and other large population centres, while the internationally recognised government based itself in the port city of Aden.
