Eight fire engines have been called to a flat blaze in south London.
Crews were called to a fire on the 13th floor of the 20-storey block in Elmira Street, Lewisham, at 4.14am.
Nearly 60 firefighters are at the scene and the cause of the fire is not yet known.
Dozens of people could be seen gathered close to the scene where a cordon was set up, some of them believed to be people who live in the block of flats.
Crews from Lee Green, Deptford, New Cross, Forest Hill and Lewisham are among those tackling the fire, the London Fire Brigade said.
Ambulance crews and police are also at the scene of the fire.
Pictures from the scene posted by the London Ambulance Service showed a number of emergency vehicles outside the block.
