Heathrow was the world's second-busiest international airport in 2024 behind Dubai, reported Reuters citing travel data firm OAG.

The fire at North Hyde electrical substation in Hayes, west London, has left not only the airport, but thousands of homes without power. The London Fire Brigade said a transformer within the substation had caught on fire, as reported by news agency PA Media.

Around 10 fire engines and 70 firefighters have been deployed to deal with the incident, and around 150 people have been evacuated from nearby properties. The cause of the fire is yet to be determined.
