Europe’s busiest airport, London’s Heathrow, will be closed for the entire day Friday, sparking travel chaos, after a fire at an electrical substation cut power to the area.

London’s counterterror police are leading the investigation into the cause of the blaze, though for now authorities say there is “no indication of foul play.”

Heathrow advised passengers not to travel to the airport and to contact airlines for further instructions, saying in a statement on social media that no flights would be landing or taking off until at least “23h59 on 21 March.”
