Heathrow Airport will be closed all day Friday after a fire at a nearby electrical substation that supplies it with power

Heathrow, Europe’s busiest airport, warns of “significant disruption” over the coming days and tells passengers not to travel “under any circumstances” until it reopens

At least 1,351 flights to and from the airport in west London could be cancelled today, according to flight tracking website Flightradar24

The implications will stretch far wider than Heathrow, and could impact flights much further afield.

The fire at the substation in Hayes has left more than 4,900 homes without power and 150 people were evacuated from surrounding properties. The cause of the fire is not yet known
