At least 200 firefighters and 40 engines on the scene of a huge fire in Latimer Road, near Notting Hill, in West London
An eyewitness who gave his name as Rio told Sky News UK he could see the fire from his kitchen window. He had been alerted to the blaze by the sound of distant smoke alarms.
It began on one side of the building but has engulfed the block in the last two hours, stretching from the second floor to the top. Rio said fire fighters could not physically reach the upper floors of the block from their trucks.
