Around 125 firefighters are tackling a blaze at central London’s famous Somerset House, a historic venue for the arts.

The London Fire Brigade said it sent crews after receiving a call just before noon local time, and that 20 fire engines had been deployed at the scene.

It added that the cause of the fire is not yet known.

Videos posted on X showed fire on the roof of the building, with smoke billowing into the air over the River Thames.
