A Chilean Mapuche blows the Trutruca (L), a typical horn, next to a man holding a poster reading "Mapuche free now" during a protest march through downtown Santiago October 9, 2006. This year marks the 514th anniversary of Christopher Columbus' arrival to the Americas. Many indigenous people in Latin America consider it the day Columbus brought slavery, disease, colonisation and genocide from Europe to the Americas. REUTERS/Victor Ruiz Caballero (CHILE)
