Heathrow Airport will be closed all day Friday after a fire at a nearby electrical substation that supplies it with power.
The fire is still burning, London Fire Brigade says, with no power at Terminal 2 and 4 as well as 5,000 homes nearby.
Counter-terrorism police are involved in investigating the fire as a “precautionary measure”, sources tell the BBC.
