Deep beneath a mountain, hundreds of centrifuges spin, enriching Iran’s uranium that Israel suspects is destined for a nuclear weapon.
The Fordow plant is protected by tonnes upon tonnes of dirt and rock, far away from prying eyes – and foreign missiles.
But as Israeli warplanes fly unchecked above Tehran, with much of the Islamic Republic’s air defences turned to smoking ruins on the ground, attention has moved to the secretive facility.
Some say only the American B-2 stealth bomber and its massive payload could breach the so-called “nuclear mountain”, while others argue troops on the ground might be able to infiltrate its corridors. Or maybe it is simply impossible, short of a nuclear strike.
Iran has repeatedly denied that it is seeking a nuclear weapon and the head of the UN’s nuclear watchdog said in June that it has no proof of a “systematic effort to move into a nuclear weapon”.

What is the Fordow facility?
The Fordow enrichment plant is one of three key pieces of nuclear infrastructure in Iran – the others being the Natanz enrichment plant and research facilities in Isfahan.
It is thought to be buried around 80m deep into the side of the mountain. It was previously protected by Iranian and Russian surface-to-air missile systems, but these may have wholly or partially knocked out during Israel’s recent attacks.
Construction is believed to have started in around 2006 and it first became operational in 2009 – the same year Tehran publicly acknowledged its existence.

In November 2020, it was believed there were 1,057 centrifuges at Fordow. These are used to separate isotopes and increase the concentration of uranium-235, needed for nuclear fuel and weapons.
In 2023, the International Atomic Energy Agency (IAEA) – the nuclear watchdog – found uranium particles enriched to 83.7% purity – near the 90% needed for a bomb – at Fordow, the only Iranian facility where this has been found.
In June 2024, the Washington Post reported on a major expansion at Fordow, with nearly 1,400 new centrifuges earmarked for the subterranean facility.

Israel has made no secret of its desire to cripple or remove Iran’s nuclear programme, describing it as an existential threat.
There is much that remains elsewhere in Iran that is capable of producing and using nuclear material.
“But of course the real big piece remains at Fordow still and this has been in the headlines quite a bit,” says Dr Alexander Bollfrass, an expert on nuclear weapons from the International Institute for Strategic Studies (IISS) thinktank.
There is also the chance that an increased focus on diplomacy brings the war to an end before the IDF can make a run at Fordow.

Could bunker buster bombs be used?
There has been a lot of talk about bunker buster bombs. These are munitions that explode twice – once to breach the ground surface and again once the bomb has burrowed down to a certain depth.
The Israelis used 60 to 80 of them in the strike that killed Hezbollah leader Hassan Nasrallah in September last year, according to Martin “Sammy” Sampson, a former air marshal and executive director at the IISS.
But Nasrallah was only 10-15m underground, Mr Sampson said, while Fordow is believed to be 80m beneath the surface.
“An awful lot of planes would be in the same place for an awful long time” to drop enough bombs to have a chance of getting to the buried facility, he added.

There is also the possibility that the US, which operates the much more powerful GBU-57 bomb, could assist with any operation at Fordow.
“My sense is that it would still take multiple strikes,” Mr Sampson said, putting it in “more and more unknown territory”.
“It would be pretty disastrous… if you put 400 planes over the top of Fordow, or you put the might of the US over Fordow, and it survived.”
Israel’s ‘contingencies’ for dealing with Fordow
Israel has suggested that it could destroy or cripple Fordow without using bombs dropped from the air.
Israel’s ambassador to the US, Yechiel Leiter, said last weekend that Israel has “a number of contingencies… which will enable us to deal with Fordow”.
“Not everything is a matter of, you know, taking to the skies and bombing from afar,” he told ABC News.
There has been talk of using special forces to raid the facility on the ground, but that has its downsides as well.
“This would be an incredibly high risk mission if you were to do something on the ground,” said Mr Sampson.
There is also the possibility Israel could replicate what happened at the Natanz enrichment plant, where the IAEA said 15,000 centrifuges were likely destroyed in the IDF bombardment of Iran.
This was possibly due to an Israeli airstrike disrupting the power supply to the centrifuges, rather than actual physical damage to the centrifuge hall, according to the nuclear watchdog.
A total of 28 people have died following Hurricane Melissa’s rampage across Jamaica, the government has confirmed.
Melissa, one of the strongest storms on record to make landfall in the Caribbean, brought with it winds of up to 185mph when it hit the island earlier this week.
The Red Cross described it as a “disaster of unprecedented catastrophe”.
Melissa ravaged through Jamaica, Haiti, the Dominican Republic, and Cuba.
It weakened by the time it reached Cuba on Wednesday morning but still brought devastation – with houses collapsed and roads blocked.
A statement from the government of Jamaica said it was “deeply saddened to confirm 28 fatalities associated with the passage of Hurricane Melissa”.
It went on: “We extend heartfelt condolences to the families, friends, and communities mourning their loved ones.”
The flight, chartered by the Foreign, Commonwealth and Development Office, was for those “unable to leave Jamaica on commercial routes”.
Essential relief supplies are now rolling into some of the hardest hit areas.

The UK government is mobilising an additional £5m in emergency humanitarian funding – on top of £2.5m announced earlier this week – to support the region’s recovery.
This new funding will enable the UK to send humanitarian supplies – including more than 3,000 shelter kits and over 1,500 solar-powered lanterns to help those whose homes have been damaged and those without power.

Jamaica victims left shell-shocked
The UK is working with the World Food Programme and Red Cross, to ensure emergency relief reaches those who need it most.
At least 25 people died in the southern Haitian coastal town of Petit-Goave after the La Digue river burst its banks as a result of the hurricane, according to the town’s mayor Jean Bertrand Subreme.
Ukraine is increasing its number of assault troops in the area, the 7th Rapid Response Corps said on Facebook.
And Ukrainian troops are also working to cut Moscow’s military logistics routes, it added.
The Russian defence ministry also said its forces defeated a team of Ukrainian special forces that headed to Pokrovsk in a bid to prevent Russian forces from advancing further into the city.

‘Footage of Ukrainian troops after surrendering’
It later posted videos of two Ukrainian troops who, it claimed, had surrendered.
The footage showed the men, one dressed in fatigues and the other in a dark green jacket, sat against a wall in a dark room, as they spoke of fierce fighting and encirclement by Russian forces.
The videos’ authenticity could not be independently verified, and there was no immediate public comment from Kyiv on the Russian ministry’s claims.

Ukraine’s President Volodymyr Zelenskyy has previously acknowledged that some Russian units had infiltrated the city. But he maintained that Ukraine is tackling them.
He said Russia had deployed 170,000 troops in Ukraine’s eastern Donetsk province, where Pokrovsk is located, in a major offensive to capture the city and claim a big battlefield victory.

Ukraine’s army chief Oleksandr Syrskyi said on Saturday the situation in Pokrovsk remained “hardest” for Ukrainian forces, who were trying to push Russian troops out.
But he insisted there was no encirclement or blockade as Moscow has claimed.
“A comprehensive operation to destroy and push out enemy forces from Pokrovsk is ongoing. The main burden lies on the shoulders of the units of the armed forces of Ukraine, particularly UAV operators and assault units,” Mr Syrskyi said.

Why is Ukraine attacking Moscow? What’s behind Putin’s nuclear test?
Why is Pokrovsk important?
One of Moscow’s key aims has been to take all of Ukraine’sindustrial heartland of coal-rich Donbas, which comprises of the Luhansk and Donetsk provinces. Kyiv still controls about 10% of Donbas.
Capturing Pokrovsk, which Russian media has dubbed “the gateway to Donetsk”, and Kostiantynivka to its northeast, would give Moscow a platform to drive north towards the two biggest remaining Ukrainian-controlled cities in Donetsk – Kramatorsk and Sloviansk.
‘Key Russian fuel pipeline struck’
Meanwhile, Ukraine’s military intelligence, known as HUR, has said its forces have hit an important fuel pipeline in the Moscow region that supplies the Russian army.

In a statement on Telegram, HUR said the operation late on Friday was a “serious blow” to Russia’s military logistics.
HUR said its forces struck the Koltsevoy pipeline, which is 250 miles long and supplies the Russian army with gasoline, diesel and jet fuel from refineries in Ryazan, Nizhny Novgorod and Moscow.
The operation, which targeted infrastructure near Ramensky district, destroyed all three fuel lines, HUR said.
The pipeline was capable of transporting up to three million tonnes of jet fuel, 2.8 million tonnes of diesel and 1.6 million tonnes of gasoline annually, HUR said.
Russia ‘targets gas production site’
Also overnight, Russia launched an attack on a gas production site in Poltava, in central Ukraine.
A fire broke out, the local administration said, but no injuries were reported.
Kyiv condemns ‘nuclear terrorism’
Ukraine’s foreign ministry has condemned Russian strikes this week on substations powering some of its nuclear plants.
It accused Russia of carrying out “targeted strikes on such substations” which “bear the hallmarks of nuclear terrorism”.
Elsewhere, a civilian died and 15 more were injured on Saturday morning after Russia struck the Mykolaiv region in southern Ukraine with a ballistic Iskander missile, local official Vitaliy Kim said.
A child was among those hurt in the strike, he added.
The death toll in Jamaica after Hurricane Melissa could rise, with certain communities still marooned from the rest of the island, according to the police chief for the worst-affected area.
Coleridge Minto, superintendent of police for St Elizabeth Parish, told Sky News that his area has recorded six deaths directly related to the hurricane.
“We are hoping there is no more,” he said. “The reality is we have not yet communicated with all our station commanders in some of the other areas and so as soon as we have those reports, we could be hearing of other injuries, other situations that we were not privy to at this moment.”
The UK has pledged a total of £7.5m to assist the Caribbean’s recovery from the hurricane. Aid flights have been arriving over the past couple of days into Jamaica’s two international airports, but it’s not getting to where they need it the most.
Image: Black River has been described as ground zero after Hurricane Melissa swept through it
In the town of Middle Quarters, close to where the hurricane made landfall, Vivienne Bennett is sitting, propped up against a house without a roof. Her right hand is wrapped in a kitchen towel. “I lost my finger in the hurricane,” she says, showing me her finger which is exposed to the bone. “I opened the door of my house to try and escape, and the wind slammed it back and cut my finger off.”
She asks me for painkillers and says she doesn’t have any medication to stave off infection. I ask if she has seen any government aid. “No,” she replies, “we haven’t seen anybody yet, so we’re trying to get some help. I need to get to a hospital but I don’t know how because all the roads are blocked.”

Her daughter, Leila, has a baby and other children are playing nearby. “We have no nappies, we have no food, we have no water,” Leila says, “it feels like the wilderness here now.”

The road leading to Black River, the town authorities are referring to as “ground zero” for this disaster, is difficult to pass, but not impossible. A journey from the capital, Kingston, that would usually take two hours, now takes six. We drive through murky floodwater, a couple of feet deep, and through an avenue of twisted bamboo stalks.
On arrival, it’s a desperate scene. People here seem almost shell-shocked, still processing what has happened to them, unsure what to do next. One man walks past our cameraman and holds his hands in the air. “Jamaica needs help,” he says, “it’s been mashed up.” I ask what help he needs. “We need houses, food and water,” he replies.
Black River was once a wealthy town, the first in Jamaica to have electricity. But the storm has laid waste to the main street. The 300-year-old church, the seafront restaurant, the pharmacy, the Chinese supermarket, the whole town has been shredded.
A group of people sit at a bus stop on the seafront surrounded by huge rocks washed up by a 16-foot storm surge. “It’s a disaster, a disaster,” one woman calls out to me.
With communications still down across most of the island, people here have been unable to contact friends and family for five days now.

A woman called Inkiru Bernard, who is Jamaican but lives in New York, has been in touch with our team and asked us to try to find her 67-year-old mother, who lives in Black River. She’s not heard from her since the storm.
When we arrive at the address she provides, her mother, Inez McRae, is sitting on the porch. She shows me around what remains of the house where she weathers the storm. The roof is entirely gone, everything is sodden and thick with mud.
“But I’m alive,” she says, “I’ve been spared.” When Inkiru finally sees her mother on a video call, she cries with relief. “Oh mummy,” she says, “I’ve been so worried.”

Tanks have been positioned on the main street in Black River and soldiers patrol it after shops and businesses were looted.
The police chief for this area, Coleridge Minto, says he understands the desperation but is urging people to be patient.
“We can appreciate that persons are trying to grab things,” he says, “persons are devastated, but we want to ensure that we maintain law.”
Army helicopters were flying over the disaster zone and some aid is now arriving into Black River. But with other villages still largely cut off from the rest of the island, this situation is growing more dire by the day.
