An indigenous Mapuche blows a Trutruca, a musical instrument, as they gather during a rally outside the main Chilean Justice building in Santiago October 24, 2012. The rally was held in support of indigenous Mapuche inmates who have been on a hunger strike for 59 days to protest against charges of attempted murder of a police officer and illegal possession of weapons, according to local media.
