Global concern about the coronavirus pandemic is growing, with a number of countries detecting confirmed cases of the Omicron variant for the first time.
Travel restrictions are also being imposed once again as governments suspend flights from southern Africa, the region where this strain was first detected.
Here is a look at the latest COVID-19 developments around the world.

Israel
On Saturday, Israel unveiled plans to ban all foreigners from entering the country.
If the proposals are approved, it will become the first nation to completely shut its borders in response to the Omicron variant.

There are fears that B.1.1.529 could be more contagious than other variants – and more resistant to vaccines.
Prime Minister Naftali Bennett said the ban would last for 14 days.

So far, Israel has one confirmed case of the Omicron variant, and seven suspected cases.
Phone-tracking technology is going to be used to locate carriers of the new variant, in an attempt to stop it being transmitted to others.

The US
From Monday, the US is going to restrict travel from South Africa and seven other countries in the region.
American citizens and permanent US residents – along with spouses and close friends – will be exempt.
No cases linked to Omicron have been detected in the country so far.
But Dr Anthony Fauci, America’s top infectious disease specialist, told NBC that he wouldn’t be surprised if the variant is already in the States, adding: “When you have a virus that is showing this degree of transmissibility … it almost invariably is ultimately going to go essentially all over.”
In separate developments, New York Governor Kathy Hochul issued a COVID-19 “disaster emergency” declaration on Friday, with infections and hospitalisations increasing in the state.

Italy
On Saturday, health officials confirmed that a case of the Omicron variant had been detected in Italy.
The business traveller had flown from Mozambique, landing in Rome on 11 November and returning to his home in Naples.
Five of his family members, including two children, have also tested positive. All are now isolating and have light symptoms.

The Omicron variant has also been detected in two travellers who arrived on a flight from South Africa on 24 November.
Although genome sequencing is yet to be completed, it is “proven without doubt that this is the variant”.
Both cases were detected in the southern state of Bavaria, and another suspected case has been found in the west of the country.

The Netherlands
Dutch health officials have detected 61 COVID-19 cases among people who flew from South Africa on Friday.
Although the Netherlands Institute for Health is “almost certain” some of these patients have the Omicron variant, further testing is required to be absolutely sure.
The KLM airline expressed surprise at the high number of cases because all passengers had either tested negative or shown proof of vaccination before boarding flights from Cape Town and Johannesburg.
Authorities in the country are now attempting to contact 5,000 passengers who have travelled from South Africa, Botswana, Eswatini, Lesotho, Mozambique, Namibia or Zimbabwe since Monday.

Quarantine requirements have been widened to a greater number of travellers in an attempt to stem the spread of the Omicron variant.
Those arriving from the UK, the Czech Republic, the Netherlands, Egypt and Malawi will now be subject to tighter restrictions.
The Federal Office of Public Health said passengers from these countries will need to present a negative COVID-19 test and quarantine for 10 days too.
Direct flights have already been banned from South Africa and the surrounding region.
Despite cases being detected in Italy and Germany, both neighbours of Switzerland, travel restrictions have not been imposed on any countries it shares borders with.

Spain
From next month, British tourists will only be able to enter Spain if they can show proof of a COVID-19 vaccination.
Until now, unvaccinated travellers were allowed into the country if they could present a negative PCR test that was take 72 hours before their arrival.
“The appearance of new variants causing (coronavirus) obliges an increase in restrictions,” the government said.
Spain’s Industry, Trade and Tourism department said approximately 300,000 British people who are resident in Spain will not be affected by the new measures.
Donald Trump’s eldest son has said his father may walk away from the Ukraine peace process, claiming the issue is not a priority for Americans, and signalling Europe needs a better plan.
In a wide-ranging discussion with Sky’s lead world news presenter Yalda Hakim at Doha Forum 2025, Donald Trump Jr addressed issues including the US administration’s recent diplomatic efforts around the world.
He was speaking in his capacity as a business leader, setting out his agenda for “America first” investments in defence technology and artificial intelligence (AI), drawing a direct line between global stability and economic prosperity.

When asked directly if he believed the US president would walk away from Ukraine, he answered: “I think he may, what’s good about my father and what’s unique about my father is you don’t know what he’s going to do. He’s unpredictable.”
President Trump has led renewed efforts for a ceasefire deal with Russia in recent months.

Drawing a parallel with his father’s current “war” on drug cartels, Donald Trump Jr described gangs bringing illegal drugs into America as a “far greater clear and present danger to the US than anything [going on] in the Ukraine or Russia”.
While he said he did not believe Ukraine would be “abandoned”, he said: “The American public doesn’t have the appetite [for endless wars and further funding of Ukraine’s military efforts].”
Describing Ukraine as “a far more corrupt country than Russia”, he characterised Ukrainian President Zelenskyy as “one of the great marketeers of all time”, who he said had become “a borderline deity, especially to the left”.
He went on to describe President Trump’s approach as “common sense”.
China rivalry was the focus, but Musk got a mention
In a country and at a conference which is friendly, even admiring of the Trump administration, Don Jr was in his element.
He’s here in his capacity as a business leader, promoting his venture, 1789 Capital which claims to be focused on “America First” investments.
But he wasn’t shy about discussing his father’s foreign policy achievements, boasting that Donald Trump had resolved seven or eight wars – conflicts that most ordinary Americans were unaware of.
His pitch is bullish and direct – the current US administration is projecting strength globally, stopping wars and creating investment opportunities which serves the American economy. It’s the MAGA mentality for the global audience.
It’s clear that the rivalry with China is their biggest focus, especially finding ways to combat their dominance over critical minerals.
“America can no longer just sit there and hope that China is going to be a good actor… I think the rest of the world understands that they want America to be at the forefront of all of that.”
When I asked him about recent efforts by President Trump to bring the war in Ukraine to an end, he responded forcefully. “We want peace, we want to stop the death.”
But he went on to say that Europe needed to shoulder the burden and currently they have no plan.
As he sat on the stage in Qatar, the country which has been at the centre of the ceasefire efforts for Gaza, he expressed hope that peace would prevail, but balanced expectations America would fund its re-construction. This would have to be a global effort.
“If there’s one thing my father is, it’s a builder… I think he can be the greatest construction manager in the history of the world, but no one in America wants to bear the entire responsibility of that.”
And, away from international diplomatic efforts, he was happy to announce a breakthrough closer to home.
The “bromance” with Elon Musk and President Trump is back on – calling the entrepreneur a “generational talent, a generational level of genius”.
‘Bromance’ back on
He also confirmed that Tesla billionaire Elon Musk was “100% back in the fold”, after previously appearing to fall out with the president.
Earlier this year, Donald Trump Jr’s investment company, 1789 Capital, heavily invested in some of Musk’s companies, including SpaceX.

Directly comparing President Trump with Musk, he said: “Imagine dealing with one Donald Trump – now I have to deal with two.
“They’re very similar that way, so it created some headaches… but the reality is they’re both very much aligned, they’re on message with what we want to do with our country. What we want to do with freedom of speech.”
He went on: “Elon did incredible things for Twitter, really allowed the democratisation of truth and freedom and free speech to occur. That’s something that is a true threat in America right now.”
He also praised Musk as “changing the face of free speech, science and technology”, adding, “we have to protect our geniuses”.
When asked whether Mr Trump would stand for a third term, he joked that he could be “just trolling” those on the left.
He went on, “He’s the most unpredictable person, probably in the history of politics. Which is why he’s able to get something done. We’ll see.”
A hidden, underground military base in eastern Ukraine is so secret, soldiers change into civilian clothes whenever they step outside to avoid drawing attention.
Journalists are not usually allowed access.
But the unit that has been using this vast, subterranean warren of war rooms, a dormitory, kitchen, canteen and makeshift gym as its headquarters since the summer is imminently relocating, so Sky News was invited inside.
Lieutenant Colonel Arsen Dimitric – call sign Lemko – is the chief of staff of 1st Corps Azov of the National Guard of Ukraine, one of the country’s most effective combat forces.

He sat with us in the base, next to a large square table, covered by a map of the Donbas region.
His soldiers have been fighting in this area since the summer, countering a surge in Russian attacks in and around the frontline city of Pokrovsk.
“We aim to destroy as much of the enemy as possible,” he said.

“Will we take losses? Yes. Will it hurt? Absolutely.”
But he said if Russia is allowed to advance, even more Ukrainians will suffer.
“Their [the Russians’] only advantage is numbers,” he said.
“They don’t care how many people they lose.”
Lemko said almost 17,000 Russian soldiers had been killed or wounded fighting in this section of the warzone alone between August to November.
Ukrainian video footage of the battlefield showed Russian armoured vehicles being taken out by drones and artillery fire.
At one point, Russian soldiers mounted on motorbikes try to advance, only to be stopped by Ukrainian fire.
“Our task is to hit them as hard as possible in various areas,” Lemko said. “We focus on our operations, others on theirs, and leadership will negotiate the best possible terms.”
The Azov Corps soldiers are fighting over land that should be handed over to Russia, according to an initial draft of a peace deal proposal between Kyiv and Moscow put forward by the United States. This is despite swathes of the Donbas remaining under Ukrainian control.
But General Oleksandr Syrskyi, the head of the Ukrainian armed forces, has since told Sky News that simply surrendering territory would be “unacceptable”.

Giving up territory ‘unacceptable’, Ukraine’s military chief says
For Lemko, he says the job of his troops is to inflict as much damage as possible on the Russian side to help strengthen Ukraine’s hand in negotiations.
“Simply giving it [land] away isn’t the way,” he said.
“Diplomats do their work, we do ours. Our job as soldiers is to give as many advantages as possible to our negotiating team. And we’re doing exactly that.”
Lemko, who has been battling against Russia since the Crimean annexation in 2014, also had a warning for the rest of Europe about a rise in hybrid attacks, such as mysterious drone sightings, acts of sabotage and cyber hacks suspected of being linked to Moscow.
He said Ukraine’s experience showed that if attacks by Russia that fall under the threshold of conventional war are not successfully countered, full-scale conflict could follow.
“Ukraine once lost a hybrid war that had been waged since the very start of our independence,” he said.
“Because of that defeat, there was a physical operation against us in Crimea and then a physical operation in 2022.
“Now the hybrid war has reached its climax, and it is moving into the Baltic States and Europe.
“That is why, in my opinion – and in the opinion of most of our officers – now is the moment for all countries to unite and counter this hybrid war. Because the consequence may be a physical one.”
