Power supplies have been returning in Spain and Portugal after large parts, including the capitals Madrid and Lisbon, were hit by a huge outage on Monday.

Millions of people were caught up in the chaos after the mass blackout brought many areas to a standstill, with trains stopping, planes grounded, internet and mobile phone services cut, traffic lights and ATMs down, and some routine hospital operations suspended.

Spain‘s interior ministry declared a national emergency and the two countries’ governments convened emergency cabinet meetings as officials tried to find out what caused the outage which started around 12.30pm (11.30am UK time).

Blackouts in Spain and Portugal: Follow latest updates

About half the electricity supplies in Spain have now been restored by the grid operator, Prime Minister Pedro Sanchez said on Monday evening, adding the rest should be back by Tuesday.

In a televised address, Mr Sanchez said authorities have not yet worked out what had caused the blackout in the Iberian Peninsula and were not ruling anything out.

He asked the public to refrain from speculation, and urged people to call emergency services only if really necessary.

Eduardo Prieto, the head of operations at Spanish power grid operator Red Electrica, said the event was unprecedented, calling it “exceptional and extraordinary”.

Meanwhile, Portugal‘s Prime Minister Luis Montenegro said power in his country would be fully restored in the coming hours.

He said all the state services remained operating in the country despite all the difficulties. He also said there was “no indication” a cyberattack was the cause.

‘Rare atmospheric phenomenon’

Portugal’s grid operator Ren claimed the outage was caused by a fault in the Spanish electricity grid, related to a “rare atmospheric phenomenon”.

Ren says that, due to extreme temperature variations in Spain, there were “anomalous oscillations” in very high-voltage lines.

It also says that given the complexity of the issue, it could take up to a week for the network to fully normalise again.

It comes as France briefly lost power following the outages in Spain and Portugal, French grid operator RTE said.

Parts of Madrid underground were evacuated and traffic lights in the city were not working, according to local media.

Play was suspended at the Madrid Open tennis tournament due to the outage – with Britain’s Jacob Fearnley forced off court in a critical moment during his third-round tie with Grigor Dimitrov.

The loss of power affected scoreboards and the camera above the court. Organisers later announced the tournament would not be able to resume on Monday, with afternoon and evening sessions cancelled.

What has been affected by the blackout?

Here’s what we know has been impacted so far:

:: Transport, including trains, metros and airports – with traffic lights also down.

:: Internet and mobile coverage.

:: Lighting in homes, businesses and other buildings, though backup generators are in place in many.

:: ATMs and card payments, as well as most till systems.

:: Lifts in buildings are stuck.

:: Electric car chargers and fuel pumps are also down.

:: Air conditioning units.

:: A significant quantity of water pumps, meaning some homes have no access to drinking water.

Airports affected

Aena, which runs international airports across Spain, said earlier that “some incidents were occurring” at the airports due to the outage.

The company added in a statement: “Contingency generators are active. Please check with your airline, as there may be disruptions to access and ground transportation.”

People ‘had nowhere to go’

Maddie Sephton, who is from west London, was on the Madrid Metro when the power outage occurred.

“We got on the train and everything was fine,” she told Sky News. “But then everything went dark.”

She was stuck on the train for 20 minutes until a staff member opened the doors manually.

Mrs Sephton says she was on her way to the airport at the time – and had to exit the station by walking up 15 flights of stairs with her luggage.

“No lifts are operating – making it difficult for elderly people with limited mobility,” she added.

Above ground, she said that “everyone is just standing around and waiting”.

Bars were unable to take card payments, cash machines are down, and traffic lights weren’t working either.

“I currently don’t have any internet service and just €15 in my wallet – I can’t withdraw any money from the ATM,” she added.

“A couple have offered to let us get a ride in their taxi to the airport. Their flight is at 4.30pm so they’re pretty relaxed – but my flight back to London is at 3pm and I’m nervous.”

Mrs Sephton said: “People are just walking but have nowhere to go, and nothing to do.”

Meanwhile, thousands of passengers had to be evacuated after the blackout left the metro service in Barcelona without power.

The blackout was also reported to have forced the closure of the city’s tram system and rendered some traffic lights there inoperable.

It has also impacted medical facilities, with hospitals in Madrid and Catalonia forced to suspend routine medical work. Staff have been able to attend to critical patients using power from backup generators.

It comes as Metrovalencia, the urban rail system, encompassing both metro and tram services in Valencia, said traffic in the city was “disrupted” due to a “general power outage in the city”.

The outage also hit the Portuguese capital Lisbon and surrounding areas, as well as northern and southern parts of the country.

Portugal’s government said the incident appeared to stem from problems outside the country, an official told national news agency Lusa.

“It looks like it was a problem with the distribution network, apparently in Spain. It’s still being ascertained,” Cabinet Minister Leitão Amaro was quoted as saying.

Fierce battle for frontline towns where Ukraine’s soldiers are surrounded

Fierce battle for frontline towns where Ukraine's soldiers are surrounded

Footage geolocated by Sky News showed Russian soldiers walking through the Shakhtarskyi neighbourhood on the outskirts of Pokrovsk on Thursday.

The video sheds light on the situation in this key frontline area, as Russian forces slowly encroach on Myrnohrad, the satellite town to Pokrovsk, and one of its last remaining outposts.

Videos geolocated by Sky News show fighting intensifying in recent weeks, as Russian forces attempt to gain control of the towns and their network of road and rail intersections.

Gaining control here would give Russia a base from which to access key cities further north that form part of Ukraine’s “fortress belt”.

Russian forces are advancing from all directions, according to the Institute for the Study of War (ISW), with only one small opening to the northwest of Myrnohrad remaining.

Estimated to be only 3km wide by military experts, this withdrawal corridor is patrolled by Russian drone units which monitor the area for moving vehicles and those who may attempt to leave on foot.

Russian forces have been advancing on Myrnohrad since late October.

Video from a Ukrainian unit in Myrnohad, posted on 29 October, shows a Russian vehicle attempting to enter the town from the northeast. The tank is attacked and soldiers attempting to enter on foot are targeted.

Video posted on 3 November shows Russian forces on the ground in the south of the town.

By 8 November, Russian strikes begin to pummel the northeast of Myrnohrad, the location of many of the town’s high-rise buildings, at that time, held by Ukrainian forces.

George Barros, Russia Team & Geospatial Intelligence Team Lead at ISW, told Sky News that Russian strategy in Pokrovsk has been to erode Ukrainian logistical capacity using drones and artillery over the course of several months.

“After denying supply lines and degrading the frontline forces by essentially cutting them off from behind and starving them out in their positions, then the Russians move forward with their infantry and frontal assaults,” Barros explained.

Capture the flag

For a brief period, it looked as though Russian forces had captured Myrnohrad.

Videos posted on 13 November appeared to show a Russian flag flying over the Myrnohrad mine.

However, video posted the following day showed a Ukrainian drone shooting it down.

Both Russian and Ukrainian forces continue to fight for control of Myrnohrad, with videos posted on the 19 and 20 November showing Russian airstrikes on Ukrainian positions in the town, and Ukrainian drone strikes targeting Russian forces on foot.

While the exact numbers of Russian and Ukrainian forces in the area remains unclear, reports indicate that three key Russian units are active in Pokrovsk and Myrnohrad, and are advancing on the towns from the north and south.

A number of Ukrainian units remain inside the towns, including the 145th Assault regiment and the 32nd, 35th, 38th and 155th Brigades. Reports indicate that more Ukrainian units have been moved into surrounding areas to hold the withdrawal corridor open.

Sky News reached out to the Ukrainian brigades still in Myrnohrad, but they declined to comment, citing military regulations.

Strategic significance

Natia Seskuria, associate international security fellow at the Royal United Services Institute (RUSI), explained that the area is important for the Ukrainians to keep and the Russians to take because of its strategic position.

“Situated at a major road and rail intersection in Donetsk Oblast, Pokrovsk has functioned as a central artery for moving troops, equipment, and supplies to Ukrainian units deployed along the surrounding front.”

Russia “would gain a platform to redirect its offensive efforts toward Ukraine’s principal defensive urban centres… including Kramatorsk and Slovyansk,” Seskuria said.

Ukrainian and Russian soldiers in Pokrovsk have fought intensely and at close quarters over the last month.

In late October US-made Black Hawk helicopters containing specialist troops directed by Ukrainian military intelligence entered Pokrovsk to try to keep the town.

But as Russian troops advance, Myrnohrad is becoming the last stronghold of Ukrainian forces in the area.

Uncertain future

At least up until 12 November, there were still civilians living in Pokrovsk and Myrnohrad, despite strikes on buildings in both cities.

A post made on that day by the Donetsk state regional administration estimated 1,200 people remain living in Pokrovsk and 900 in Myrnohrad.

Evacuation is only possible with the help of the military or police, and it is not clear how many have evacuated in the 11 days since.

Barros of ISW says gaining Pokrovsk would increase Russia’s leverage at the negotiating table.

“If the Russians can successfully convince enough international leaders that, okay, the Russians took Pokrovsk, they’re going to take the next thing, and they’re going take the thing, so now let’s negotiate, then that is a strategic victory for the Russians.”

Torrential rain triggers deadly flooding and landslides in Vietnam

Torrential rain, flooding and landslides has left more than 100 people dead or missing in Vietnam.

Rainfall has exceeded 74.8in (1.9 metres) in some parts of central Vietnam over the past week.

The region is a major coffee production belt and home to popular beaches, but it is also prone to storms and floods.

Fatalities have been reported in Dak Lak province and the neighbouring Khanh Hoa province.

Footage has been released by local police of a dramatic rescue, involving a drone which airlifted a stranded man to safety from an island in the middle of the Serepok River, Dak Lak province.

The government estimates the flooding has cost the economy around 8.98 trillion dong (£260m).

More than 235,000 houses were flooded and nearly 80,000 hectares of crops were damaged, Vietnam’s disaster agency said.

On Thursday, VietnamNet newspaper said that a suspension bridge on Da Nhim River in Lam Dong province had been swept away.

Video footage posted online showed the bridge being swallowed by the river in just a few seconds.

Naval forces have been deployed to help stranded citizens in Khanh Hoa, the Vietnam News Agency reported, adding that floodwaters had reached record highs in many areas.

Photos shared in state media reports showed residents, including children, sitting on the roofs of flooded houses in Khanh Hoa, Gia Lai and Dak Lak provinces.

A seven-year-old girl was rescued late on Wednesday in Da Lat, the capital of Lam Dong province, after being buried by a landslide, the Nhan Dan newspaper reported.

The landslide, triggered by heavy rain, knocked down and buried part of the house where the girl was staying.

She was pulled out after an hour and a half and was taken to hospital with a broken leg, according to the report.

Several airlines cancel Venezuela flights after ‘hazardous situation’ warning

Several airlines cancel Venezuela flights after 'hazardous situation' warning

Three international airlines have cancelled flights departing from Venezuela after a “potentially hazardous situation” warning.

The US Federal Aviation Administration (FAA) on Saturday issued an alert to airlines flying over the country, citing the “worsening security situation and heightened military activity in or around Venezuela“.

The US is poised to launch a new phase of operations related to the South American nation in the coming days, four US officials said.

The exact timing or scope of the operations, as well as whether President Donald Trump has made the final decision to act, have not yet been established.

Brazil’s Gol, Colombia’s Avianca and TAP Air Portugal cancelled their flights from the capital, Caracas, in north Venezuela, on Saturday, according to Flightradar24 and the official website of Simon Bolivar Maiquetia International Airport.

TAP Air Portugal confirmed it cancelled flights scheduled for Saturday and next Tuesday.

“This decision follows information issued by the United States aviation authorities, which indicates that safety conditions in Venezuelan airspace are not guaranteed,” the airline said.

The Trump administration has been considering Venezuela-related options to tackle what it has portrayed as President Nicolas Maduro’s role in supplying illegal drugs that have killed Americans.

Venezuela’s president has denied having any links to the illegal drug trade.

Mr Maduro, who is celebrating his 63rd birthday on Sunday and has been in power since 2013, has claimed Mr Trump is looking to oust him and that Venezuelan citizens and the military will rally against any such attempt.

Aeronautica Civil de Colombia said in a statement there were “potential risks” of flying in the Maiquetia area “due to the deterioration of security conditions and increased military activity in the region”.

Spain’s Iberia also said it was cancelling its flights to Caracas from Monday until further notice.

Reports of looming action have been growing in recent weeks as the US military has deployed forces to the Caribbean, amid heightened tensions with Venezuela. The Pentagon referred questions to the White House and the CIA declined to comment.

There has been a huge US military build-up in the region, including the US Navy’s largest aircraft carrier, USS Gerald R Ford, at least eight other warships, and F-35 aircraft.

The build-up in the Caribbean has been rumbling on for months, and Mr Trump has authorised covert CIA operations in Venezuela.

The US plans on Monday to designate the Cartel de los Soles, a Venezuela-based alleged criminal group, a foreign terrorist organisation for what the US sees as its role in importing illegal drugs into America, officials said.
