Fire crews in west London are tackling a huge blaze which has broken out close to Heathrow Airport.

At least 10 fire engines and 70 firefighters have been scrambled to the site on an industrial estate on Church Road in Heston, near Hounslow.

In a statement, London Fire Brigade (LFB) said: "10 fire engines and around 70 firefighters are tackling a fire at an industrial estate on Church Road in Heston.

"Several units in the industrial estate over two floors are on fire. The Brigade was called at 2.01am.

"Fire crews from Heston, Southall, Feltham, Hayes and Kingston are at the scene.

"The cause of the blaze is not yet known."

In an update, the LFB said several units were alight at the industrial estate.

Nearby Church Road at the junction of Heston Road, as well as Westbrooke Road and Sonia Gardens have been closed to traffic.

The industrial estate has been shut off.

People have been urged to avoid the area, while those who live nearby have been told to keep their windows and doors closed due to the smoke.

It comes as the last two Heathrow Airport-based Boeing 747 planes are set to make their final flights later today.

The G-CIVB and G-CIVY 747 models are set to take off at 8.30am on Thursday, if the weather remains safe.

It comes following the retirement of British Airway's fleet of 747-400, which was brought forward as a result of the impact the Covid-19 pandemic has had on the airline and the aviation sector.

The flight will be live-streamed on the airline's Facebook page, with enthusiasts and customers encouraged to share any special memories or photos of British Airways' 747s at 7.47am and 7.47pm using the hashtag #BA747farewell.
