Hundreds of people clashed with riot police as they took to the streets of Vina de Mar on Sunday, as Latin America's biggest music festival was planned to kick off.
Footage shows cars and other objects set ablaze by protesters, with some of them clashing with riot police. Officers tried to disperse protesters with tear gas and by deploying water cannons.
The protesters, armed with Molotov cocktails and what they found on the streets, targeted the Vina del Mar music festival - Latin America's biggest and oldest music festival - where Grammy-winning musician Ricky Martin was scheduled to perform.
Ricky Martin has previously called on Chilean President Sebastian Pinera to respect his citizen's will and to "listen to [his] people."
Chile has been rocked by nation-wide protests since October, which were triggered by a now-withdrawn increase in subway fares. Social discontent has been fuelled by frustration with Pinera's policies and growing inequality.
