About 70 firefighters are tackling a blaze on the top floor of a house in south-east London.
Ten fire engines from London Fire Brigade were called to Chelsfield Hill in Orpington, at about 02:15 BST where they found a semi-detached home ablaze.
People in the area are being advised to keep their windows and doors closed.
Clive Robinson, station commander, said: “Crews are working extremely hard to bring this large fire under control.”
