Even after US strikes, Iran may still have the ability to make a nuclear bomb

It would be sensible to wait until the dust has settled before judging whether the US strikes on Iran were, in Donald Trump’s, words, “a spectacular military success”.

And when dropping bombs that weigh more than 13 tonnes each, there’s going to be a lot of dust.

The Pentagon says the operation against Iran’s three largest nuclear facilities involved 125 military aircraft, warships and submarines, including the largest operational strike by B2 bombers in history.

The B-2s dropped 14 of America’s most powerful GBU-57 “bunker buster” bombs on the Natanz uranium enrichment plant and Iran’s most sophisticated nuclear facility at Fordow.

The first time, according to the Pentagon, the weapons have been used in a military operation.

The Fordow complex, buried deep in a mountain, was the only site not previously damaged by Israeli strikes over the last few days.

The use of multiple GBU-57 bombs at Fordow is telling.

Despite their size, it was known that one of them would be insufficient to penetrate 80+ metres of solid rock believed to shelter Iran’s most sophisticated uranium enrichment technology deep within Fordow.

Satellite images reveal three visible holes at two different strike points on the mountainside above the complex.

The sites appear to be close to what may have been ventilation shafts – possibly chosen to maximise damage below and render the facility useless.

Using several of the bombs in the same location is likely designed to allow each to penetrate further than the first before detonating.

If nuclear facilities at Isfahan, Natanz and Fordow were destroyed – as the US claims – or even crippled, it would certainly halt Iran’s ability to enrich the Uranium needed to make a viable nuclear weapon.

But that’s not the same as preventing Iran’s ability to make a nuclear bomb. To do that, they need “weapons-grade” uranium; the necessary metal-shaping, explosives and timing technology needed to trigger nuclear fission in the bomb; and a mechanism for delivering it.

The facilities targeted in the US raid are dedicated to achieving the first objective. Taking naturally occurring uranium ore, which contains around 0.7% uranium 235 – the isotope needed for nuclear fission – and concentrating it.

The centrifuges you hear about are the tools needed to enrich U-235 to the 90% purity needed for a compact “implosion”-type warhead that can be delivered by a missile.

And the reality is Iran’s centrifuges have been spinning for a long time.

United Nations nuclear inspectors warned in May that Iran had at least 408kg of uranium “enriched” to 60%.

Getting to that level represents 90% of the time and effort to get to 90% U-235. And those 400kg would yield enough of that weapons-grade uranium to make nine nuclear weapons, the inspectors concluded.

The second element is something Iran has also been working on for two decades.

Precisely shaping uranium metal and making shaped explosive charges to crush it in the right way to achieve “criticality”, the spark for the sub-atomic chain reaction that releases the terrifying energy in a nuclear explosion.

In its recent bombing campaign, Israel is thought to have targeted facilities where Iranian nuclear scientists were doing some of that work.

But unlike the industrial processes needed to enrich uranium, these later steps can be carried out in laboratory-sized facilities. Easier to pack up and move, and easier to hide from prying eyes.

Given that it’s understood Iran already moved enriched uranium out of Fordow ahead of the US strike, it’s far from certain that Iran has, in fact, lost its ability to make a bomb.

And while the strikes may have delayed the logistics, it’s possible they’ve emboldened a threatened Iran to intensify its warhead-making capability if it does still have one.

Making a more compact implosion-based warhead is not easy. There is debate among experts about how advanced Iran is along that road.

But if it felt sufficiently motivated, it does have other, less sophisticated nuclear options.

Even 60% enriched uranium, of which – remember – it has a lot, can be coaxed to criticality in a much larger, cruder nuclear device.

This wouldn’t pose as much threat to its enemies, as it would be too heavy to fit on even the best of Iran’s long-range missiles.

But it would, nonetheless, elevate Iran to the status of a nuclear power.

Before and after images of Jamaica show destruction left by Hurricane Melissa

The scale of the destruction left by Hurricane Melissa as it tore across Jamaica is now being revealed by the first photos taken by satellites.

The eye of the storm made landfall on the southwest coast of the island, 75 miles from the capital Kingston, on Tuesday.

Before and after images from Vantor’s satellites show the impact of the 185mph winds on the town of Black River, the capital of St Elizabeth Parish.

Use the sliders below to see the same areas of Jamaica before and after the hurricane struck.

There is widespread damage. Some houses and businesses are without roofs, and others have been destroyed altogether.

The covered food market is in ruins. So is St John Anglican church, one of the oldest in Jamaica – only its bell tower still stands.

Houses that lined the shore would have born the brunt of the storm surge.

Further along the coast is the fishing village of White House.

Streets have been reduced to piles of rubble. Trees have been stripped of their leaves by the wind.

The west of Jamaica is the country’s bread basket, important for growing food.

But fields are underwater, flooded by up to a metre of rain that fell as the vast storm system passed over.

Many crops will have been destroyed and the government has appealed for vegetable seeds so farmers can quickly plant crops again.

On the northwest coast is the resort of Montego Bay.

The container terminal and oil storage tanks in the port have been inundated by the storm surge and are surrounded by water.

It’s estimated that 400,000 people in Jamaica have been affected by the hurricane.

And the cost of the devastation is immense.

Estimates by hazard analysts Enki Research put the bill at £5.8bn. That’s more than a third of Jamaica’s GDP – a measure of its economic wealth.

It will take months and international support to put Jamaica back on its feet.

Donald Trump says tariffs will be cut after ‘amazing’ meeting with Xi Jinping

Donald Trump says tariffs will be cut after 'amazing' meeting with Xi Jinping

Donald Trump has described crucial trade talks with Chinese President Xi Jinping as “amazing” – and says he will visit Beijing in April.

The leaders of the world’s two biggest economies met in South Korea as they tried to defuse growing tensions – with both countries imposing aggressive tariffs on exports since the president’s second term began.

Catch up on Trump-Xi meeting

Aboard Air Force One, Mr Trump confirmed tariffs on Chinese goods exported to the US will be reduced, which could prove much-needed relief to consumers.

It was also agreed that Beijing will work “hard” to stop fentanyl flowing into the US.

Semiconductor chips were another issue raised during their 100-minute meeting, but the president admitted certain issues weren’t discussed.

“On a scale of one to 10, the meeting with Xi was 12,” he told reporters en route back to the US.

Xi a ‘tough negotiator’, says Trump

The talks conclude a whirlwind visit across Asia – with Mr Trump saying he was “too busy” to see Kim Jong Un.

However, the president said he would be willing to fly back to see the North Korean leader, with a view to discussing denuclearisation.

Mr Trump had predicted negotiations with his Chinese counterpart would last for three or four hours – but their meeting ended in less than two.

The pair shook hands before the summit, with the US president quipping: “He’s a tough negotiator – and that’s not good!”

It marks the first face-to-face meeting between both men since 2019 – back in Mr Trump’s first term.

There were signs that Beijing had extended an olive branch to Washington ahead of the talks, with confirmation China will start buying US soybeans again.

American farmers have been feeling the pinch since China stopped making purchases earlier this year – not least because the country was their biggest overseas market.

Chinese stocks reached a 10-year high early on Thursday as investors digested their meeting, with the yuan rallying to a one-year high against the US dollar.

Analysis: A fascinating power play

Sky News Asia correspondent Helen-Ann Smith – who is in Busan where the talks took place – said it was fascinating to see the power play between both world leaders.

She said: “Trump moved quickly to dominate the space – leaning in, doing all the talking, even responding very briefly to a few thrown questions.

“That didn’t draw so much as an eyebrow raise from his counterpart, who was totally inscrutable. Xi does not like or respond well to unscripted moments, Trump lives for them.”

On Truth Social, Mr Trump had described the summit as a gathering of the “G2” – a nod to America and China’s status as the world’s two biggest economies.

While en route to see President Xi, he also revealed that the US “Department of War” has now been ordered to start testing nuclear weapons for the first time since 1992.

Tens of thousands killed in two days in Sudan city, analysts believe

Tens of thousands killed in two days in Sudan city, analysts believe

Tens of thousands of people have been killed in the Sudanese city of Al Fashir by the Rapid Support Forces (RSF) in a two-day window after the paramilitary group captured the regional capital, analysts believe.

Sky News is not able to independently verify the claim by Yale Humanitarian Labs, as the city remains under a telecommunications blackout.

Stains and shapes resembling blood and corpses can be seen from space in satellite images analysed by the research lab.

Nathaniel Raymond, executive director of Yale Humanitarian Labs, said: “In the past 48 hours since we’ve had [satellite] imagery over Al Fashir, we see a proliferation of objects that weren’t there before RSF took control of Al Fashir – they are approximately 1.3m to 2m long which is critical because in satellite imagery at very high resolution, that’s the average length of a human body lying vertical.”

Mini Minawi, the governor of North Darfur, said on X that 460 civilians have been killed in the last functioning hospital in the city.

The Sudan Doctors Network has also shared that the RSF “cold-bloodedly killed everyone they found inside Al Saudi Hospital, including patients, their companions, and anyone else present in the wards”.

World Health Organisation (WHO) chief Dr Tedros Adhanom Ghebreyesus said it was “appalled and deeply shocked” by the reports.

Satellite images support the claims of a massacre at Al Saudi Hospital, according to Mr Raymond, who said YHL’s report detailed “a large pile of them [objects believed to be bodies] against a wall at one building at Saudi hospital. And we believe that’s consistent with reports that patients and staff were executed en masse”.

In a video message released on Wednesday, RSF commander Mohamed Hamdan Dagalo acknowledged “violations in Al Fashir” and claimed “an investigation committee should start to hold any soldier or officer accountable”.

The commander is known for committing atrocities in Darfur in the early 2000s as a Janjaweed militia leader, and the RSF has been accused of carrying out genocide in Darfur 20 years on.

Sources have told Sky News the RSF is holding doctors, journalists and politicians captive, demanding ransoms from some families to release their loved ones.

One video shows a man from Al Fashir with an armed man kneeling on the ground, telling his family to pay 15,000. The currency was not made clear.

In some cases, ransoms have been paid, but then more messages come demanding that more money be transferred to secure release.

Muammer Ibrahim, a journalist based in the city, is currently being held by the RSF, who initially shared videos of him crouched on the ground, surrounded by fighters, announcing his hometown had been captured under duress.

He is being held incommunicado as his family scrambles to negotiate his release. Muammer courageously covered the siege of Al Fashir for months, enduring starvation and shelling.

The Committee to Protect Journalists regional director Sara Qudah said the abduction of Muammar Ibrahim “is a grave and alarming reminder that journalists in Al Fashir are being targeted simply for telling the truth”.
