Protests continue to rock Chile after a government hike in public transport fares last month sparked a revolt against austerity and economic inequality. On Thursday, police fired tear gas and water cannons to clear the streets of the capital Santiago as protests marked the first anniversary of the death of Camilo Catrillanca, a Mapuche indigenous activist who was shot in the head last November. Four officers are set to go on trial for his homicide later this month. At least 20 people have been killed, and over 1,000 others injured, since protests erupted last month.
