LONDON (AP):

A fire that broke out at Olympic Park caused no major damage or injuries, London 2012 event organisers and the city's fire brigade said yesterday.

The brigade said the fire in containers holding 100 kilos (220 pounds) of dry wood ash at the renewable energy centre on the north plaza of the park started late Monday.

Four engines and 25 firefighters responded to the 10:30 p.m. GMT (1730 EDT) blaze, extinguishing it in the early hours of Tuesday. Some remained at the park for safety reasons.

Olympics organisers described the cause of the blaze as mech-anical, 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."
