A university building in central London was evacuated after a fire broke out in a basement storeroom.
About 100 people fled the scene after flames broke out at the Strand campus of King’s College University shortly before 1.35pm on Thursday.
Fire crews from six fire stations were scrambled to the scene.
Six fire engines and 25 crew members were still tackling the blaze more than an hour after the sub-basement store cupboard went up in flames.
Pictures from the scene show fire crews surrounding the building, with hose pipes running from fire engines into the university campus.
Students and staff were warned to avoid the building while the incident was dealt with.
A London Fire Brigade spokeswoman said: “Six fire engines and 35 firefighters and officers have been called to a fire at a university building on Strand.
“Part of a store room in a sub-basement of the university building is currently alight. Approximately 100 people left the building before the arrival of the brigade.
“The brigade was called at 1.34pm. Fire crews from Euston, Islington, Bethnal Green, Soho, Dowgate and Chelsea fire stations are at the scene.
“The cause of the fire is currently unknown.”
A King’s College London spokeswoman since said: “A fire has broken out in the basement of the Macadam building but is now under control.
"The building has been evacuated. Fire services remain in attendance on site. King’s students and staff are asked to avoid the Macadam and Chesham buildings in Surrey Street on the Strand Campus until further notice.”
