The death toll in Chile rose to 13 amid violent demonstrations against a metro price hike, Spanish news agency EFE reported late Monday.
Most of the deaths were caused during Sunday’s looting when shops set on fire.
The Chilean government declared a 15-day state of emergency on Saturday, extending it later from north to south.
In addition to the Metropolitan Region, home to some 7 million people, emergency was also extended in Valparaiso, Concepcion, Rancagua, Coquimbo and La Serena, and Antofagasta.
"We are at war against a powerful enemy, one willing to use violence without bounds," Sebastian Pinera, Chile's president, said in a live Twitter broadcast late Sunday.
Stressing that it is not the time for ambiguity, Pinera called on Chileans to unite against violence and delinquency.
