Around 125 firefighters are tackling a fire in a block of flats in west London.

Twenty fire engines responded to a report this afternoon of a blaze on Elm Road, Wembley.

London Fire Brigade says part of the building’s roof is alight.

The block and surrounding buildings have been evacuated as a precautionary measure, the brigade says.

It added that nearby residents are being advised to keep their doors and windows shut to stay safe from any smoke in the area.

A statement said: “People are advised to avoid the area as crews respond.

“One of the Brigade’s 32 metre turntable ladders is being used as a water tower to help extinguish the fire.

“Control Officers have taken eight calls reporting the fire, with the first received at 16.42. Firefighters from Wembley, Park Royal, Northolt and surrounding fire stations are at the scene.”

So far, the cause of the blaze is not yet known.
