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

London Fire Brigade (LFB) said part of the building's roof was alight but later said it had been brought under control at around 10pm.

The block and surrounding buildings were evacuated as a precautionary measure, the brigade said.

All those who lived in the building were accounted for following the evacuation.

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

An LFB statement said: "People are advised to avoid the area as crews respond.

"Two of the Brigade's 32-metre turntable ladders are being used as a water tower to help extinguish the fire.

"Control Officers have taken six 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."

The cause of the blaze remains unknown.
