An indigenous Mapuche man is detained by riot policemen during clashes outside a court where Celestino Cordova, a 27-year-old indigenous Mapuche healer known as "Machi" attended to hear his sentence, in Temuco city, some 689 km (428 mile) south of Santiago, February 28, 2014. A court on Friday sentenced Cordova to 18 years in prison for his participation in the killing of a couple during an arson attack last year in a high-profile case that rekindled divisions over land rights in Chile.
