Forty fire engines and around 225 firefighters are battling a blaze at a block of flats in Dagenham, east London.

More than 100 people were evacuated from the building on Freshwater Road.

The London Fire Brigade (LFB) said it was called at 2.44am on Monday with crews from Dagenham, Ilford, Romford, Barking and surrounding fire stations at the scene.

The brigade said parts of the scaffolding surrounding the building, as well as the ground floor and the roof, were alight.

Four people had to receive medical treatment from the London Ambulance Service.

Two people were taken to hospital because of their injuries.

The cause of the fire has not been established.

Video footage showed thick black smoke rising above the building. The fire brigade used a drone to see where the flames were most intense.

Station commander Alan Bendell is at the scene and said: “The fire is producing heavy smoke and we’re advising local residents to keep windows and doors closed.

“Two of the brigade’s 32-metre turntable ladders are being used at the scene as aerial water towers to assist with tackling the fire from height.”

An ambulance service spokesperson said: “We treated four patients at the scene and took two of them to a hospital.”
