US President Joe Biden has been overheard saying that Vladimir Putin’s war in Ukraine carries the greatest risk of nuclear weapons being used since the Cuban missile crisis in 1962.
Speaking at a Democratic Party fundraiser in New York on Thursday, Mr Biden said: “For the first time since the Cuban missile crisis, we have a direct threat of the use of nuclear weapons if, in fact, things continue down the path they are going.
“We have not faced the prospect of Armageddon since Kennedy and the Cuban missile crisis.”
Mr Putin himself has also threatened the use of Russia’s vast nuclear arsenal.
Last month he said: “I want to remind you that our country also has various means of destruction… and when the territorial integrity of our country is threatened, to protect Russia and our people, we will certainly use all the means at our disposal.”

Why is Biden talking about nuclear Armageddon?
In the face of unexpected, successful counter-offensives by the Ukrainians in recent weeks, some Western intelligence officials and defence analysts believe the Kremlin could resort to drastic measures to save face.
According to Russia’s nuclear doctrine, it could launch a first-strike nuclear attack if the country’s existence was deemed to be at risk.

Given Mr Putin’s claims about why he started the war, any involvement of NATO troops in the Ukraine conflict could put this plan into action.
And after Moscow staged ‘referenda’ on annexing four areas of Eastern Ukraine, its leader could also use a Ukrainian attack on any of those territories to justify a nuclear strike.
If that did happen, NATO would have to respond, but currently officials have suggested they would only use conventional weapons in retaliation.
Several analysts believe that although Mr Putin says he is “not bluffing” any nuclear activity by Russia would be just as damaging for him – as it would for the West – and is therefore unlikely.

What was the Cuban missile crisis?
The Cuban missile crisis is considered the closest the world has ever come to nuclear annihilation.
The 13-day showdown in 1962 came during the Cold War and after the US discovered the Soviet Union had secretly deployed nuclear weapons to Cuba.

Responding to the presence of American ballistic missiles in Italy and Turkey, as well as the failed Bay of Pigs Invasion of Cuba in 1961, Soviet leader Nikita Khrushchev agreed to place missiles on the island – just a few hundred miles from the US coastline.
In response, then-US president John F Kennedy ordered a naval quarantine of the island to prevent further missiles from being delivered.
After several days of tension, Mr Kennedy and Mr Khrushchev reached an agreement for the Soviet Union to dismantle their weapons in Cuba in exchange for Mr Kennedy promising the US would not invade the island.
The US also secretly agreed to dismantle all of its medium-range ballistic missiles in Turkey.

It saw the warring geopolitical powers establish the Moscow-Washington hotline to facilitate quick and direct communication between them in the event of tensions escalating again.
Although the two leaders came to an agreement not to deploy the weapons, bitter tensions between the US and Soviet Union until the end of the Cold War in 1991 left the rest of the world fearing a nuclear attack for decades after.
‘Protect and survive’ adverts warned Britons of nuclear attacks
Those who lived through the 1970s and 1980s in Britain will remember the government’s ‘Protect and Survive’ campaign.
Designed to prepare people for a nuclear attack and supposedly give them the best chance of surviving, it came in the form of pamphlets, TV and radio adverts.

Nuclear threat readiness video from 1975
One example recorded for use on BBC Radio 4 said: “This is the Wartime Broadcasting Service. This country has been attacked with nuclear weapons.
“Communications have been severely disrupted, and the number of casualties and the extent of the damage are not yet known.
“We shall bring you further information as soon as possible. Meanwhile, stay tuned to this wavelength, stay calm and stay in your own house.”
Drills were also carried out in schools, workplaces and public buildings.
Air sirens used in the Second World War were repurposed and would be used to deliver attack warnings and ‘fallout warnings’ in the event of a nuclear incident.
The word ‘fallout’ refers to harmful radioactive material released by nuclear explosions.
Adverts advised people to move to the safest area of the house – known as the ‘fallout’ room – the furthest away from exterior wars and preferably on the ground floor or in the basement.

Families were instructed to close their windows and doors, draw their curtains, and even build an ‘inner refuge’ within the fallout room.
Fashioned by propping a door or wooden plank against the wall, people were advised to cover it with sand-filled bags or suitcases.
Families also had instructions to ration food, water and other essentials in the event of a nuclear strike, as they would be advised to stay in their fallout room for at least two days afterwards.
Their fatalistic tone had a lasting psychological and cultural impact on the population, in a similar way to the 1980s ‘Don’t Die of Ignorance’ HIV/AIDS awareness campaign.
A famine has been declared in Gaza City and the surrounding neighbourhoods.
The Integrated Food Security Phase Classification (IPC) – a globally recognised system for classifying the severity of food insecurity and malnutrition – has confirmed just four famines since it was established in 2004.
These were in Somalia in 2011, and in Sudan in 2017, 2020, and 2024.
The confirmation of famine in Gaza City is the IPC’s first outside of Africa.
“After 22 months of relentless conflict, over half a million people in the Gaza Strip are facing catastrophic conditions characterised by starvation, destitution and death,” the report said, adding that more than a million other people face a severe level of food insecurity.

Over the next month conditions are also expected to worsen, with the famine projected to expand to Deir al-Balah and Khan Younis, the report said.
Nearly a third of the population (641,000 people) are expected to face catastrophic conditions while acute malnutrition is projected to continue getting worse rapidly.

What is famine?
The IPC defines famine as a situation in which at least one in five households has an extreme lack of food and face starvation and destitution, resulting in extremely critical levels of acute malnutrition and death.
Famine is when an area has:
• More than 20% of households facing extreme food shortages
• More than 30% of children suffering from acute malnutrition
• A daily mortality rate that exceeds two per 10,000 people, or four per 10,000 children under five
Over the next year, the report said at least 132,000 children will suffer from acute malnutrition – double the organisation’s estimates from May 2024.
Israel says no famine in Gaza
Volker Turk, the UN Human Rights chief, said the famine is the direct result of actions taken by the Israeli government.
“It is a war crime to use starvation as method of warfare, and the resulting deaths may also amount to the war crime of wilful killing,” he said.
COGAT, the Israeli military agency that coordinates aid, has rejected the findings.
Israel accused of allowing famine to fester in Gaza
Tom Fletcher, speaking on behalf of the United Nations, did not mince his words.
Gaza was suffering from famine, the evidence was irrefutable and Israel had not just obstructed aid but had also used hunger as a weapon of war.
His anger seeped through every sentence, just as desperation is laced through the report from the Integrated Food Security Phase Classification (IPC).
Conditions are expected to worsen, it says, even though the Gaza Strip has been classified as a level 5 famine. There is no level 6.
But it took only moments for the Israeli government to respond in terms that were just as strident.
Israel’s foreign ministry said there is no famine in Gaza: “Over 100,000 trucks of aid have entered Gaza since the start of the war, and in recent weeks a massive influx of aid has flooded the Strip with staple foods and caused a sharp decline in food prices, which have plummeted in the markets.”
Another UN chief made a desperate plea to Israel’s prime minister to declare a ceasefire in the wake of the famine announcement.
Tom Fletcher, UN under-secretary general for humanitarian affairs, said famine could have been prevented in the strip if there hadn’t been a “systematic obstruction” of aid deliveries.
“My ask, my plea, my demand to Prime Minister Netanyahu and anyone who can reach him. Enough. Ceasefire. Open the crossings, north and south, all of them,” he said.
The IPC had previously warned famine was imminent in parts of Gaza, but had stopped short of a formal declaration.

The latest report on Gaza from the UN Office for the Coordination of Humanitarian Affairs (OCHA) says there were almost 13,000 new admissions of children for acute malnutrition recorded in July.
The latest numbers from the Gaza health ministry are 251 dead as a result of famine and malnutrition, including 108 children.
But Israel has previously accused Hamas of inflating these figures, saying that most of the children who died had pre-existing health conditions.
The Ukrainian suspected of coordinating attacks on the Nord Stream pipelines had served in Ukraine’s Secret Service and in the Ukrainian Army’s special forces, Sky News understand.
Serhii K., 49, was arrested in northern Italy on Thursday following the issuance of a European arrest warrant by German prosecutors.
It is not known whether he was still serving at the time of the pipeline attack in 2022 and Ukraine’s government has always denied any involvement in the explosions.
According to sources close to the case, the suspect has been found in a three-star bungalow hotel named La Pescaccia in San Clemente, in the province of Rimini.

Man arrested over Nord Stream attacks
When military officers from Italy’s Carabinieri investigative and operational units raided his bedroom, he didn’t try to resist the arrest.
The hotel’s employees have been questioned, but no further evidence or any weapons were found, the sources added.
Serhii arrived on Italy’s Adriatic coast earlier this week, and the purpose of his trip was a holiday. He was found with his two children and his wife.

At least one of the four people within his family had a travel ticket issued in Poland. He crossed the Italian border with his car with a Ukrainian license plate last Tuesday.
He was travelling with his passport, and he used his real identity to check into the hotel, triggering an emergency alert on a police server, we have been told.

After the arrest, he was taken to the Rimini police station before being moved to a prison in Bologna, the regional capital, on Friday.
Deputy Bologna Prosecutor Licia Scagliarini has granted the German judicial authorities’ requests for Serhii’s surrender, but Sky News understands the man told the appeal court that he doesn’t consent to being handed over to Germany.
He also denied the charges and said he was in Ukraine during the Nord Stream sabotage. He added that he is currently in Italy for family reasons.
While leaving the court, he was seen making a typical Ukrainian nationalist ‘trident’ gesture to the reporters.
The next hearing is scheduled for 3 September, when the Bologna appeal court is set to decide whether Serhii will be extradited to Germany or not. He will remain in jail until then.
In Germany, he will face charges of collusion to cause an explosion, anti-constitutional sabotage and the destruction of structures.
German prosecutors believe he was part of a group of people who planted devices on the pipelines near the Danish island of Bornholm in September 2022.
Serhii and his accomplices are believed to have set off from Rostock on Germany’s north-eastern coast in a sailing yacht to carry out the attack.
The explosions severely damaged three pipelines transporting gas from Russia to Europe. It represented a significant escalation in the Ukraine conflict and worsening of the continent’s energy supply crisis.
According to a US intelligence report leaked in 2023, a pro-Ukraine group was behind the attack. Yet, no group has ever claimed responsibility.

Sky News understands Genoa’s Prosecutor’s Office in northern Italy has requested their colleagues in Bologna to share the information related to Serhii.
Anti-terrorism prosecutors are investigating another alleged sabotage linked to the Russian shadow fleet oil tanker Seajewel, which sank off the port of Savona last February.
On Thursday, they asked an investigative police unit to figure out whether there is a link between that episode and the Nord Stream attacks.
