A massive power outage paralyzed Spain and Portugal on Monday in an incident with no immediate explanation.

“It’s best to not speculate. We will know the causes soon. We are not discarding any hypothesis, but right now, we just focus on what’s most important: returning electricity to our homes,” Spanish Prime Minister Pedro Sánchez said at a news conference Monday.

The stoppage, which occurred about 12:30 p.m. Madrid time, caused chaos across the Iberian Peninsula and showed the vulnerability of Europe’s electrical grid — even on days without extreme weather or spiking demand.

Trains stopped running. Hospitals canceled surgeries, according to news agencies, and depended on backup generators. Business ground to a halt as machines were unable to process credit card transactions. The outage even suspended several Madrid Open tennis matches, with photos showing a court with nonfunctioning scoreboards and darkened stands. Sánchez urged citizens to restrict cellphone use and to call emergency dispatchers only “when it is really necessary.”

By about 5:30 p.m. Madrid time, Red Eléctrica, the corporation that operates Spain’s electricity grid, said some power had been restored across corners of the peninsula, including parts of Catalonia, the Basque Country and Andalusia. About two hours later, the utility provider said more than a fifth of the peninsula’s power had been recovered. Full recovery may take up to 10 hours, Red Eléctrica told Spanish news outlets, which means the country’s power could be restored some time late Monday.

“Causes are being analyzed, and all resources are being dedicated to addressing the issue,” Red Eléctrica said in a statement.

More than 50 million people live on the Iberian Peninsula, but authorities did not provide an immediate estimate for the number of people affected by the outage. Portugal’s national grid operator described it as a “massive cut” in electricity supply across the peninsula. Data from Red Eléctrica showed a sudden plunge in electricity demand from about 27,000 megawatts to less than 13,000. Levels remained abnormally low two hours later.

Spain’s Energy Ministry said in a statement that Sara Aagesen, a deputy prime minister, visited the Red Eléctrica control center to “learn about the situation firsthand and monitor the incident.”

“All necessary measures will be put in place to restore normality as quickly as possible,” the statement said.

Prime Minister Sánchez also held a meeting at the control center, with Aagesen and several other ministers present, the Spanish newspaper El País reported, and Spain’s National Security Council called a meeting to address the outage.

Portugal’s Lusa News Agency said the country’s cybersecurity center had seen no evidence so far that the blackout stemmed from a cyberattack. Separately, the Reuters news agency quoted unnamed officials as saying a cyberattack had not been ruled out.

The Spanish grid also connects with Morocco, France, Andorra and Portugal. Spain and France experienced a major blackout on July 24, 2021, but it lasted less than an hour.

Previous power outages in Europe have been caused by technical problems, lightning strikes and damaged cables. In 2003, Italy faced a huge blackout because a tree was too close to a power line, resulting in a flashover, or a jump of electricity from the line to vegetation.

Russian President Vladimir Putin has announced a temporary ceasefire for the war in Ukraine.

The Kremlin said the ceasefire would run from the morning of 8 May until 11 May – which coincides with victory celebrations to mark the end of World War Two.

In response, Ukraine’s Foreign Minister Andrii Sybiha called for an immediate ceasefire lasting “at least 30 days”.

While US President Donald Trump, who has been attempting to broker a truce between the two sides, said he wants to see a permanent ceasefire, the White House said.

The Kremlin announced a similar, 30-hour truce over Easter, but while both sides reported a dip in fighting, they accused each other of hundreds of violations.

Ceasefires have been attempted more than 20 times in Ukraine – all of them failed eventually, and some within minutes of going into effect.

The most recent one, over Easter, was very limited in scope and only resulted in a slight reduction in fighting, with both sides accusing each other of violating the truce.

In a statement on Monday, the Kremlin said Putin declared the ceasefire “based on humanitarian considerations”.

A translation of the statement said: “Russia believes that the Ukrainian side should follow this example.

“In the event of violations of the ceasefire by the Ukrainian side, the Armed Forces of the Russian Federation will give an adequate and effective response.

“The Russian side once again declares its readiness for peace talks without preconditions, aimed at eliminating the root causes of the Ukrainian crisis, and constructive interaction with international partners.”

Following its release, Ukrainian Foreign Minister Sybiha said: “If Russia truly wants peace, it must cease fire immediately.”

“Why wait until May 8th?” he wrote on X. “If the fire can be ceased now and since any date for 30 days—so it is real, not just for a parade.”

He said Ukraine is ready to support a “lasting, durable, and full ceasefire. And this is what we are constantly proposing, for at least 30 days”.

White House press secretary Karoline Leavitt said Trump was growing “frustrated with leaders of both countries”.

“He wants to see a permanent ceasefire.

“I understand Vladimir Putin this morning offered a temporary ceasefire. The president has made it clear he wants to see a permanent ceasefire first to stop the killing, stop the bloodshed.”

The latest announcement comes during what the US has described as a “very critical” week for Russia-Ukraine peace talks.

Washington has been trying to broker a deal between the two sides, but the Donald Trump administration has threatened to pull out if they do not see progress.

Putin is keen to create the impression that Russia is serious about seeking peace – and he is keen for Trump to hear that message given Ukraine has accepted Washington’s proposal for a more lasting 30-day ceasefire.

It comes after the US president expressed annoyance with Russia’s continued attacks on Ukraine.

Russia launched a full-scale invasion of Ukraine on 24 February 2022, and currently controls about 20% Ukraine’s territory, including the southern Crimea peninsula annexed by Moscow in 2014.

It is estimated that hundreds of thousands of people – the vast majority of them soldiers – have been killed or injured on all sides since 2022.

A massive explosion and fire rocked a port Saturday in southern Iran purportedly linked to a shipment of a chemical ingredient used to make missile propellant, killing 14 people and injuring around 750 others.

Helicopters and aircraft dumped water from the air on the raging fire through the night into Sunday morning at the Shahid Rajaei port. The explosion occurred just as Iran and the United States met Saturday in Oman for the third round of negotiations over Tehran’s rapidly advancing nuclear program.

No one in Iran outright suggested that the explosion came from an attack. However, even Iranian Foreign Minister Abbas Araghchi, who led the talks, on Wednesday acknowledged that “our security services are on high alert given past instances of attempted sabotage and assassination operations designed to provoke a legitimate response.”

State media offered the casualty figures. But there were few details on what sparked the blaze just outside of Bandar Abbas, causing other containers to reportedly explode.

Security firm says port received chemical for missile fuel

The port took in a shipment of the missile fuel chemical in March, the private security firm Ambrey said. The fuel is part of a shipment of ammonium perchlorate from China by two vessels to Iran first reported in January by the Financial Times. The chemical used to make solid propellant for rockets was going to be used to replenish Iran’s missile stocks, which had been depleted by its direct attacks on Israel during the war with Hamas in the Gaza Strip.

“The fire was reportedly the result of improper handling of a shipment of solid fuel intended for use in Iranian ballistic missiles,” Ambrey said.

Ship-tracking data analyzed by The Associated Press put one of the vessels believed to be carrying the chemical in the vicinity in March, as Ambrey said. Iran hasn’t acknowledged taking the shipment. The Iranian mission to the United Nations didn’t respond to a request for comment on Saturday.

It’s unclear why Iran wouldn’t have moved the chemicals from the port, particularly after the Beirut port blast in 2020. That explosion, caused by the ignition of hundreds of tons of highly explosive ammonium nitrate, killed more than 200 people and injured more than 6,000 others. However, Israel did target Iranian missile sites where Tehran uses industrial mixers to create solid fuel.

Social media footage of the explosion on Saturday at Shahid Rajaei saw reddish-hued smoke rising from the fire just before the detonation. That suggests a chemical compound being involved in the blast — like in the Beirut explosion.

“Get back get back! Tell the gas (truck) to go!” a man in one video shouted just before the blast. “Tell him to go, it’s going to blow up! Oh God, this is blowing up! Everybody evacuate! Get back! Get back!”

On Saturday night, the state-run IRNA news agency said that the Customs Administration of Iran blamed a “stockpile of hazardous goods and chemical materials stored in the port area” for the blast, without elaborating.

An aerial shot released by Iranian media after the blast showed fires burning at multiple locations in the port, with authorities later warning about air pollution from chemicals such as ammonia, sulfur dioxide and nitrogen dioxide in the air. Schools and offices in Bandar Abbas will be closed Sunday as well.

Port a major destination for Iranian cargo

Shahid Rajaei has been a target before. A 2020 cyberattack attributed to Israel targeted the port. It came after Israel said that it thwarted a cyberattack targeting its water infrastructure, which it attributed to Iran. Israeli officials didn’t respond to requests for comment regarding Saturday’s explosion.

Social media videos showed black billowing smoke after the blast. Others showed glass blown out of buildings kilometers, or miles, away from the epicenter of the explosion. State media footage showed the injured crowding into at least one hospital, with ambulances arriving as medics rushed one person by on a stretcher.

Hasanzadeh, the provincial disaster management official, earlier told state television that the blast came from containers at Shahid Rajaei port in the city, without elaborating. State television also reported that there had been a building collapse caused by the explosion, though no further details were offered.

The Interior Ministry said that it launched an investigation into the blast. Iranian President Masoud Pezeshkian also offered his condolences for those affected in the blast.

Shahid Rajaei port in Hormozgan province is about 1,050 kilometers (650 miles) southeast of Iran’s capital, Tehran, on the Strait of Hormuz, the narrow mouth of the Persian Gulf through which 20% of all oil traded passes.
