CANBERRA, Dec. 15 (Xinhua) -- A group of Australian Greenpeace activists climbed Sydney Opera House and unfurled a protest banner on the top calling for action by world leaders at the Copenhagen climate summit, local media reported Tuesday.
Police were called to the Sydney Opera House at 8:15 a.m. local time on Tuesday, following reports that five people had climbed a sail of the building.
Five Greenpeace activists successfully unfurled the 100 square meter banner, which read "Stop The Politics, Climate Treaty Now", from the top of the eastern sail of the Opera House at 9:20 a.m..
The banner, which was taken down shortly afterwards, is calling for world leaders to deliver a legally binding climate treaty at the climate summit in Copenhagen.
Greenpeace chief executive Linda Selvey said the activists, two men and three women, were highly trained and had practiced the stunt beforehand.
She said one Greenpeace activist had been arrested, but police could not confirm the arrest.
