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.

Switzerland
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.
A controversial Israeli minister has said Gaza could be a “real estate bonanza” – and that a business plan for redeveloping it had been sent to the US president.
Bezalel Smotrich, the country’s far-right finance chief, told a Tel Aviv conference he had “started negotiations” with the US on how to share the proceeds of any future deal.
The comments echo controversial remarks by Donald Trump in February, when he said America would take over Gaza and redevelop it into the “riviera of the Middle East” – with its population going to “various domains”.
He later shared a AI-generated video showing it as a Dubai-style city, featuring exotic beaches, skyscrapers, luxury yachts and people partying.
Mr Smotrich told the urban regeneration event “there’s a business plan set by the most professional people there is and is on President Trump’s table and how this thing turns into a real estate bonanza. I’m not kidding; it pays off”.
Mr Smotrich said Israel had “paid a lot of money for this war, so we need to divide how we make a percentage on the land marketing later in Gaza”.
He added: “We’ve done the demolition phase, which is always the first phase of urban renewal. Now we need to build; it’s much cheaper.”

Tanks roll into Gaza as Israeli offensive begins
Any effort to forcibly displace Gaza’s population for a building project would almost certainly breach the Geneva Convention and cause international outrage – as Mr Trump found when he mooted his plan earlier this year.
Thousands are heading south with whatever they can in an effort to avoid being killed in the fighting.
The operation has prompted widespread condemnation, with UK Foreign Secretary Yvette Cooper calling it “utterly reckless and appalling”.
Ms Cooper – who helped greet the pro-Israel President Trump when he landed in Britain on Tuesday – said it would “only bring more bloodshed, kill more innocent civilians & endanger the remaining hostages”.
With no sign of an imminent ceasefire in Gaza and the situation increasingly dire, Prime Minister Sir Keir Starmer is expected to shortly announce Britain’s recognition of a Palestinian state.
It is believed he could make the declaration at the weekend to avoid causing division on the issue while President Trump is in the country.

Sky News analysis shows major escalation in war
The two leaders are holding talks today at Chequers, with the prime minister under pressure to urge Mr Trump to use his influence over Israel to rein in its new offensive.
France, Canada and Australia are also set to recognise a Palestinian state at the UN General Assembly next month, while Ireland, Spain and Norway all took the step last year.
Israel says the recognition of a Palestinian state is unacceptable, rewards Hamas, and makes it harder to create the conditions needed to free the remaining hostages.
More than 65,000 people in Gaza have now been killed in the war, according to the Hamas-run health ministry. The figure does not specify the number of Hamas members killed.
At least 63 people were killed on Wednesday, with most of the casualties in Gaza City, local health authorities said.
The Hamas terror attack on Israel in October 2023 saw around 1,200 people killed and 251 people taken hostage. Forty-eight remain in Gaza, but fewer then half are thought to still be alive.
Sky News analysis shows thousands of families remain in crowded tent camps in Gaza City, with the UN estimating last week that a million people remain there.
Israel, however, believes 40% of the population has already fled south and on Wednesday opened a new evacuation route for 48 hours.
Ukraine’s defence of the crucial city of Pokrovsk, which has held out for more than a year despite fierce Russian assaults, could be coming to an end as invading forces squeeze the resistance out.
Elsewhere, Ukraine’s troops are facing attacks along the frontline, with Moscow reportedly using a pipeline to move personnel in the northeast near Kupyansk as it seeks to create even more pressure on Kyiv’s stretched resources.
Sky News has a look at what has been happening at some key parts of the frontline.
‘Kill zone’ as around Pokrovsk
Ukrainian forces have been engaged in a bitter struggle to hold the key logistics hub of Pokrovsk for more than a year, with Russian troops at times attempting to encircle the defenders there.
The situation there is worsening, says Dr Marina Miron, an expert at the defence studies department at King’s College London.
She cited reports that Russian forces are controlling all supply routes and have “created a kill zone” using drones, making it very difficult for Ukraine to resupply its troops there.

Sky’s exclusive interview with Zelenskyy: What are the key takeaways?
A road and rail node, Pokrovsk had a pre-war population of around 60,000 people. It’s viewed by Russia as “the gateway to Donetsk”.
Capturing it would severely hamper Ukrainian supply lines and endanger crucial cities like Kramatorsk and Sloviansk.
“It will take time because what the Russians are trying to do essentially is to squeeze the Ukrainians out,” Dr Miron told Sky News.
“They don’t want to storm the city as it’s too difficult and too manpower intensive – assuming a lot of losses.” Instead, they are trying to surround it completely, she added.
This reflects a “changed approach”, Dr Miron says, with the Russian military appearing to favour slower encirclement operations rather than the high-casualty assault waves with which places like Bakhmut were captured.
Meanwhile, Russian forces have advanced near Kupyansk in northeast Ukraine, not far from the fortress city of Kharkiv, the Institute for the Study of War thinktank reported on Monday.
Like other targets along the Ukrainian frontline, Kupyansk is a key transport and logistics hub, being the location at which several major rail lines converge.
“It seems like they are pretty close,” Dr Miron said, discussing the positions of Russian forces around Kupyansk.

Earlier this week, Ukraine’s military said Russia had moved personnel to the area via a pipeline, but said the exit from the pipe is under control of Ukrainian defenders.
“A counter-sabotage operation is underway in the city, and search and strike operations are underway around the city,” the Kyiv’s General Staff said on Telegram on Saturday.

Kupyansk, which was recaptured by Ukrainian troops in their counteroffensive in autumn 2022, has been largely destroyed in the course of the war and continues to face attacks.
Dr Miron said it’s likely that the push towards Kupyansk is part of an effort by Moscow to retake some of those lost territories, or perhaps an effort to seize land that it can then use as a bargaining chip in any future negotiations.
The suspect in the Madeleine McCann case celebrated his release from prison with a fast-food breakfast of chicken nuggets and a burger.
Christian B, 49, was smuggled from a jail near Hanover, hidden in the back of his lawyer’s car and managed to avoid being filmed or pictured by scores of camera operators who had been waiting for several days.
But a photographer caught up with him as he stopped briefly at a McDonald’s restaurant.
Christian B, who cannot be fully identified under German privacy laws, stood outside and smoked a cigarette before eating his food.
Dressed in a lilac shirt, beige trousers and trainers, he ordered chicken nuggets with sweet-and-sour sauce, a burger and a hot drink.
He wore sunglasses, but they did little to disguise the distinctive features that have appeared on TV and on the front of newspapers around the world.

He was driven off again in the black Audi saloon in which his lawyer Friedrich Fulscher had collected him an hour earlier from Sehnde prison.
It’s not known where Christian B was headed after completing an unrelated sentence for the rape of an elderly woman, or who will help him adjust to his new life of freedom.
As part of his release conditions, he’s been fitted with an electronic ankle tag, has had to surrender his passport and register his permanent address with probation officers.
Another of his lawyers, Philipp Marquort, said: “This is an attempt by the public prosecutor’s office to keep him in a kind of pre-trial detention where they would have access to him at any time. We will not accept that.”
German prosecutor Hans Christian Wolters, who leads the Madeleineinvestigation, believes Christian B abducted and murdered the three-year-old during a family holiday in Portugal in 2007.
The suspect, who has convictions for child sex abuse, theft, drug trafficking and forgery, denies any involvement.

Madeleine McCann suspect released from jail
Madeleine vanished from her bed in a rented apartment as her parents and their friends dined nearby at the hotel complex in Praia da Luz.
Mr Wolters told Sky News he had “almost” enough evidence to charge the suspect, but could not justify arresting him and stopping him from being freed.
He said: “He is dangerous, a psychopath, and we hope he does not commit more crimes, but it is likely he will.”
He said he hadn’t ruled out the chance of charging Christian B: “At the moment, we still have lines of investigation we are pursuing, and we hope we may gain more evidence or indications.
“If that happens, our situation would of course improve, and we would prefer to go to court with that stronger position.”

Christian B, who flitted between Germany and Portugal, has served seven years for the rape of a 72-year-old American woman in Praia da Luz – two years before Madeleine vanished.
He is expected to appear in a German court next month to face a charge of using insulting behaviour towards a female prison warder. A conviction could put him back in jail.
He also faces a possible retrial after the prosecutor’s appeal against his acquittal last year on unrelated rape and child sex allegations.
Scotland Yard detectives, who failed to charge anyone in their own investigation, revealed this week they had asked Christian B to answer their questions, but he refused, as he has with their German and Portuguese colleagues.
His lawyers dismissed it as an illegal request because investigators had shared none of the prosecution files with him.
According to the prosecutor, the evidence against Christian B in the Madeleine case is circumstantial; his mobile phone was nearby her apartment at the time she vanished, he was a convicted child sex abuser, he had allegedly confessed to a friend, and he had re-registered his car the day after.
There is no forensic evidence to link the suspect to the abduction – and after 18 years, the chances of finding it must be remote.

‘Different theory’ in McCann case
German criminal profiler Mark T Hofmann told Sky News: “I’m a big believer in second chances, but I’m not that much of a big believer in tenth chances.
“So if you commit a crime, and you do it again and again and again and again, then you need to ask yourself like, why should we believe that he will stop now?
“I wish, and I hope that also he realises that he can maybe now live a different life anonymously in some place, and hopefully stop committing crimes.”
Madeleine’s parents Kate and Gerry McCann, from Leicestershire, cling to the hope their daughter might still be found alive, in the absence of any evidence they are aware of to show she is dead.
