A firefighter, left, works Friday to extinguish the flames of the home of a wealthy landowner in Temuco, Chile. The elderly couple, Werner Luchsinger, 75, and wife wife Vivian McKay, whose family's vast landholdings have long been targeted by Mapuche Indians in southern Chile were killed in the arson attack early Friday while trying to defend their home. Chile's president quickly flew to the scene and announced new security measures, including the application of Chile's tough anti-terrorism law and the creation of a special police anti-terror unit backed by Chile's military.
