Three people have been killed by a fire inside a supermarket in Santiago during a second night of protests in Chile.

Two people died at the scene and another died in hospital after the store was looted, Santiago’s regional governor, Karla Rubilar, said.

President Piñera has suspended the rise in metro fares that sparked the protests, but unrest has continued.

Soldiers and tanks were deployed after the government declared a state of emergency and imposed a night curfew.

The protests have broadened to reflect general discontent about the high cost of living in one of Latin America’s most stable countries.
