G20: Australians bury heads in sand in climate protest
More than 400 people stuck their heads in the sand on Australia's Bondi Beach on Thursday, to protest at the country's stance on climate change.
The demonstrators said they were angry at Prime Minister Tony Abbott's reluctance to add the issue to the agenda of a G20 summit this weekend.
They dug holes on the famous beach and placed their heads inside, in a bid to show world leaders they do not agree with Mr Abbott.
