Heathrow Airport is to remain shut until midnight after a large fire at a nearby electricity substation, disrupting travel for thousands of passengers.
Tracking site Flightradar24 estimates 1,357 flights would be affected (679 into and 678 out of Heathrow) today, including around 120 which were already in the air this morning before the shutdown.
Energy Secretary Ed Miliband told Sky News “it was too early to know” what caused the “catastrophic fire”.
Passengers have been warned to stay away from the airport and all trains to Heathrow have been suspended.

Substation fire near Heathrow Airport
“To maintain the safety of our passengers and colleagues, we have no choice but to close Heathrow until 23h59 on 21 March 2025,” Heathrow said in a statement.
“We expect significant disruption over the coming days and passengers should not travel to the airport under any circumstances until the airport reopens.”

Planes usually begin landing and taking off at around 5am after the regular overnight quiet period.
Around 120 flights were bound for Heathrow when the airport announced it would be closing for the day. Some will have turned back to the airport they departed from. But others were already crossing the Atlantic and have been diverted to airports in Europe.

Data from Flightradar24 shows Amsterdam has taken the most diversions at seven, while Gatwick, Frankfurt and Shannon have all taken six flights each.
Heathrow is one of the world’s busiest airports and had a record 83.9 million passengers last year, with a plane landing or taking off around every 45 seconds.
Flightradar24 estimates that means there are about 220,000 passengers using the hub every day.
Its total closure is set to have knock-on effects on airline operations around the world for several days to come.
Matt, who is waiting at Canada’s Vancouver International Airport, told Sky News that British Airways “have been great” and they had been rebooked for a flight on Saturday. “Fingers crossed Heathrow is open!” he added.
But Raman who is stuck in Dubai said: “Flight keeps getting delayed – just seems crazy that BA won’t cancel it considering Heathrow is closed anyway. Zero comms from BA.”

‘It’s all dark here, mate’: Fire cuts Heathrow power
British Airways, the biggest carrier at Heathrow, reiterated that customers should not go to the airport until further notice.
A statement said: “This will clearly have a significant impact on our operation and our customers and we’re working as quickly as possible to update them on their travel options for the next 24 hours and beyond.”
Gatwick Airport said in a statement that it is “supporting by accepting diverted flights as required” and that it is operating “as normal today”.
Meanwhile Ryanair has launched what it is calling eight “rescue flights” for passengers affected by the Heathrow closure.

16,000 homes without power
The fire that caused the power outage is at a substation in Hayes, about 1.5 miles to the north of the airport, and an estimated 16,000 homes nearby are also without electricity.
London Fire Brigade (LFB) said the blaze was now under control and, while there have been no casualties, crews evacuated 29 people from neighbouring properties.

Backup generator also failed
Energy Secretary Ed Miliband told Sky News there was a backup generator but it was also affected by what he called a “catastrophic fire”.
He described the situation as “unusual and unprecedented” adding it was “too early to know” what caused the substation blaze.
Fire was ‘significant incident’
LFB Assistant Commissioner Pat Goulbourne said it was a “significant incident” but crews “successfully contained the fire and prevented further spread”.
“While power has been restored to some properties, we continue to work closely with our partners to minimise disruption,” he added. Local residents have been told to keep their windows and doors closed.
Scottish and Southern Electricity Networks said shortly after midnight that a “widespread power cut” was affecting Hayes, Hounslow and surrounding areas.
A graphic on the company’s website suggested around 16,000 homes were affected.
Sudan’s military has said it has retaken the Republican Palace in Khartoum, the last heavily guarded bastion of rival paramilitary forces in the capital, after nearly two years of fighting.
The current conflict in Sudan erupted in April 2023 when a power struggle between the leaders of the military and the Rapid Support Forces (RSF) boiled over into open fighting in Khartoum and other cities.
Social media videos showed the military’s soldiers inside on the 21st day of Ramadan, the holy Muslim fasting month.

A Sudanese military officer wearing a captain’s epaulettes made the announcement in a video and confirmed the troops were inside the compound.
The Republican Palace was the seat of government before the war erupted and is immortalised on Sudanese banknotes and postage stamps.

Horrors Sudan’s children face
Its recapture by the military marks another gain for Sudan’s military which has made steady advances in recent months.
The rival RSF has been mostly expelled from the capital of Khartoum after Sudan’s war began in April 2023.
Gunfire was heard in the capital overnight on Friday, although whether this was from fighting or celebrations is unclear.
The RSF hasn’t acknowledged the loss of the presidential palace but the group still holds territory elsewhere in Sudan so fighting is likely to continue.
The war has killed more than 28,000 people, according to UN figures, and forced millions to flee their homes.
Israeli strikes killed at least 85 Palestinians across the Gaza Strip overnight and into Thursday, according to the Hamas-run health ministry.
Five UN staff members have also been killed, according to the head of the UNRWA.
It comes as fighting in the enclave has restarted in recent days.
Philippe Lazzarini, head of UNRWA, the United Nations Palestinian relief agency, said on Thursday: “In the past few days, another five UNRWA staff have been confirmed killed, bringing the death toll to 284.
“They were teachers, doctors and nurses: serving the most vulnerable.”
He added he feared “the worst is yet to come”.
“Under our daily watch, people in Gaza are again and again going through their worst nightmare,” he said in a statement.
“An endless unleashing of the most inhumane ordeals.”

Speaking in Parliament, Foreign Secretary David Lammy said the UK government opposed the resumption of Israel’s hostilities and added that a British national was among the wounded when a UN compound was struck on Wednesday.
Israel has previously said it only targets militants and blames civilian deaths on Hamas because it operates in densely populated areas.
It denied previous reports it had targeted a UN compound.

Israel resumes strikes
On Tuesday, Israel resumed heavy airstrikes on the enclave killing more than 400 people, bringing to a halt the ceasefire that had paused fighting in the 17-month war.
The militant group wanted to move onto phase two to negotiate Israel’s permanent withdrawal from Gaza, the release of hostages in exchange for more prisoners and an eventual end to the war.
The tone has changed totally. It’s a remarkable turnaround from the Oval Office meltdown to the perfect phone call.
President Trump is wholly transactional. His desire for give and take far outweighs any ideological instincts. He has no particular alignment to Ukraine or, for that matter, to Russia.
He just wants a deal. Peace would stop the killing as he has said repeatedly. It would also allow for deals which can benefit America: recouping the taxpayer money spent on Ukraine and reconnecting the American economy with Russia.

Will Trump turn on Putin?
But trumping all that is his legacy and his image. He wants to be seen as the peacemaker president.
Since the Oval Office moment, Ukraine’s President Zelenskyy seems now to have recognised all that.
Ukraine’s approach towards Trump has changed. Zelenskyy is now playing his game: transactionalism.
The minerals deal hasn’t dissolved. The indications I am getting is that it’s essentially been upgraded and broadened to a wider scope: fuller economic cooperation.

The old adage is: “If you are not at the table, you are on the menu.” That’s too true with President Trump.
Zelenskyy now feels like he’s at the table and I am told he doesn’t feel coerced.
The challenges remain huge though: he doesn’t trust Putin. That’s what he tried to tell President Trump in the Oval Office. The performance that day proved to him that Trump is inclined to trust Putin.
Zelenskyy must use transactionalism to draw an impatient Trump in.
President Trump is in a hurry for a deal. He’s inclined to accept wholly disingenuous commitments from Russia, or as one source put it to me: “Trump has a high tolerance for bullshit…”
