About 150 firefighters and 25 fire engines were battling a blaze in London’s historic law district on Sunday morning after a fire broke out in an office building in Holborn’s Chancery Lane.
The London Fire Brigade was called to the scene at 10.40pm on Saturday after reports of a fire on the roof of a six-storey building.
A large amount of the roof and parts of the third, fourth and fifth floors remain alight, it said.
About 28 people left the building before emergency services arrived and 11 people have been evacuated from nearby flats as a precaution.
The cause of the fire is not yet known.
