A fire that broke out at the Olympic Park caused no major damage or injuries, London 2012 event organisers and the city's fire brigade said today.
The brigade said the fire in containers holding 100 kilos (220 pounds) of dry wood ash at the renewable energy center on the north plaza of the park started late last night .
Four engines and 25 firefighters responded to the 10.30pm blaze, extinguishing it in the early hours of this morning. Some remained at the park for safety reasons.
Olympics organisers described the cause of the blaze as mechanical, but did not elaborate.
"It was dealt with quickly and safely," the committee said in a statement. "There is no permanent damage and work on the Olympic Park continues as usual. We are working with the fire brigade and contractor to investigate the cause."
