Heathrow Airport closed affecting more than 200k passengers
The airport announced early on Friday it would be closed until 11.59pm because of a fire at a nearby electrical substation.
Around 200,000 passengers have been affected by the closure of what is Europe’s busiest airport.
Online flight tracking service Flightradar24 said more than 1350 flights were scheduled to take off or land at the airport on Friday.
“We will provide an update when more information on the resumption of operations is available.
"We know this will be disappointing for passengers and we want to reassure that we are working as hard as possible to resolve the situation.”
Passengers are being advised not to travel to Heathrow "until further notice" and instead should contact the airline they are supposed to be travelling with for more information.
