More than 100 people have been evacuated after a fire in a building partly used as a block of flats in east London.

Scaffolding surrounding the building in Freshwater Road, Dagenham, was alight, as well as parts of the ground to sixth floors and the roof when the London Fire Brigade (LFB) was called at 02:44 BST.

Four people were treated by the London Ambulance Service (LAS) at the scene, with two taken to hospital.

The cause of the fire is not yet known, LFB has said.

Thick black smoke can be seen pouring from the building, with flames flaring up at times. LFB has put up a drone to assess where efforts need to be concentrated.

Forty fire engines and 225 firefighters were sent to Freshwater Road, which has been closed to traffic.

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."

Several ambulances are parked nearby, and the LAS said the air ambulance was dispatched.

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

Crews from Dagenham, Ilford, Romford, Barking and surrounding fire stations are at the scene.

LFB is describing the property as a "mixed-used residential and commercial building".
