Counter-terrorism police have taken over the investigation into a major electrical substation fire that forced the closure of London Heathrow Airport, amid growing speculation that it may be part of a Russian sabotage campaign targeting Western infrastructure.
The blaze, which broke out at the North Hyde electrical substation on Wednesday night, caused a significant power outage, leaving thousands of homes in darkness and forcing more than 100 residents to evacuate. The fire triggered a massive explosion, leading to the immediate suspension of flights at Heathrow, the UK’s busiest airport, affecting more than 1,300 scheduled arrivals and departures.
The incident comes amid heightened concerns over Russia’s alleged involvement in covert attacks across Europe, with security analysts warning that the fire fits a broader pattern of disruption linked to Vladimir Putin’s ongoing efforts to destabilize the West.
Investigators Examine Possible Sabotage
Scotland Yard’s Counter Terrorism Command has assumed control of the probe as authorities work to determine whether the fire was a deliberate act of sabotage or a catastrophic infrastructure failure.
Western intelligence agencies have repeatedly accused Russian operatives of orchestrating a series of attacks on European energy grids, transportation networks, and other critical infrastructure since the invasion of Ukraine in 2022. While the Kremlin has denied any involvement in such activities, security officials believe Russia has been engaged in a covert “hybrid war” strategy designed to sow chaos and weaken Western resolve in supporting Ukraine.
Security expert Will Geddes, director of the International Corporate Protection Group, told MailOnline:
“If I were a foreign hostile party looking to cause maximum disruption, an electrical substation supplying the UK’s busiest airport would be a prime target. Russia has been systematically testing Western vulnerabilities, from undersea communication cables to nuclear plants. This incident certainly raises red flags.”
MPs and industry experts have also raised concerns over Heathrow’s reliance on a single power substation, with some blaming the removal of diesel-powered backup generators in favour of Net Zero alternatives.
Global Travel Chaos as Heathrow Shuts Down
The closure of Heathrow has triggered a travel crisis, with over 200,000 passengers stranded as flights were canceled, rerouted, or forced to return to their departure points. Some transatlantic flights bound for Heathrow were forced to turn back mid-air, while others were diverted to alternative airports, adding to the chaos.
Comparisons have been drawn to past large-scale aviation disruptions, with some observers likening the impact to the immediate aftermath of the 9/11 attacks. Hotel prices in and around Heathrow have surged by as much as £946 overnight as desperate travelers scramble for alternative accommodation.
Aviation analyst Paul Charles estimated the financial impact of the shutdown to be in the range of £20 million per day, with no certainty that Heathrow will resume operations on Saturday.
Experts Warn of Ongoing Infrastructure Vulnerabilities
Russia analysts and national security experts have warned that the Heathrow fire exposes a dangerous weakness in the UK’s critical infrastructure.
Bob Seely, a Russia expert and former Conservative MP, said the fire should serve as a wake-up call:
“This has exposed a massive security vulnerability. If one substation fire can shut down a major international airport, it raises serious concerns about our national resilience. We must strengthen our defenses against both sabotage and infrastructure failures.”
He added that while early indications suggest an accidental fire, the scale of the impact highlights the urgent need to bolster security around key national infrastructure assets.
Professor Lucy Easthope, an adviser on disaster response, echoed those concerns:
“Whether this fire was caused by an electrical fault or an act of sabotage, it highlights how vulnerable our national infrastructure is. We need greater resilience planning to ensure that a single failure does not bring an entire airport to a standstill.”

Russian Response and Rising Tensions
The fire has sparked a wave of speculation online, with pro-Kremlin commentators and Russian state media responding to accusations of sabotage with mockery. The Russian government has dismissed claims of involvement as “Western hysteria.”
Dmitry Medvedev, Russia’s former president and current deputy chair of the Security Council, sarcastically tweeted:
“I’m waiting for Britain to blame Russia for the Heathrow fire. What’s taking them so long?”
Meanwhile, Russian-linked social media accounts have joked about the involvement of notorious GRU agents Anatoliy Chepiga and Alexander Mishkin—suspects in the 2018 Salisbury Novichok poisoning—suggesting they might have been “on vacation” near Heathrow when the fire broke out.
Despite Kremlin denials, intelligence experts remain on high alert for further incidents, warning that Western infrastructure remains a prime target for cyber and physical attacks.
Government Response and Next Steps
Energy Secretary Ed Miliband confirmed that the UK government is working urgently to restore power and assess the cause of the fire. A formal Cobra meeting has not yet been convened, but the government is under pressure to reassure the public about national security and infrastructure resilience.
Labour MP Ruth Cadbury, chair of the Commons Transport Committee, said:
“It is deeply concerning that a single substation failure can paralyze one of the world’s largest airports. This raises serious questions about our energy and transport infrastructure.”
As counter-terrorism officers continue their investigation, security services remain on high alert. Whether the Heathrow fire was an accident or a deliberate act of sabotage, experts agree on one thing: the UK’s critical infrastructure must be better protected against future threats.
