Dozens of firefighters have battled a small fire in the basement of a 13-storey tower housing a data centre in east London.
Eight engines and around 60 crew members were called to Nutmeg Lane in Blackwall at 4.50am on Saturday.
London Fire Brigade said part of a basement battery room in the tower, storing around 200 LED acid batteries, was destroyed by fire.
No further damage to the building and no injuries reported.
The cause of the flames, which was brought under control before 7am, has not been determined.
Crews from Poplar, Millwall, Plaistow, Stratford, East Ham and East Greenwich attended the incident because it was in a high-rise, LFB added.
