London's Heathrow airport closed after massive fire causes power outage

London’s Heathrow Airport has suspended all operations until midnight on March 21 following a major power failure triggered by a fire at an electrical substation.
The disruption has resulted in widespread flight cancellations, with authorities strongly advising passengers to avoid travelling to the airport until further notice.
In a statement on X, Heathrow officials confirmed, “A fire at an electrical substation supplying the airport has caused a significant power outage. To ensure the safety of passengers and staff, Heathrow will remain closed until 23:59 on March 21. Travellers should not come to the airport and are urged to contact their airline for further details. We regret the inconvenience caused.”

Officials warned that the impact of the outage would extend over the coming days, urging passengers to refrain from attempting to reach the airport until operations resume.
Emergency crews are currently addressing the situation, but there is no clear timeline for when power will be restored. In response, Heathrow has temporarily ceased all flight operations as a safety measure.
Travellers are advised to stay in contact with their airlines for the latest updates, as disruptions to flight schedules are expected to continue.
