Chilean president declares state of catastrophe as wildfires kill at least 15

Fires blaze through 8,500 hectares, forcing 50,000 people to evacuate as firefighters struggle to extinguish flames

Wildfires raging across central and southern Chile have killed at least 15 people, scorched thousands of hectares of forest and destroyed scores of homes, authorities said, as the South American country swelters under a heatwave.

Chile’s president, Gabriel Boric, declared a state of catastrophe in the country’s central Biobío region and the neighbouring Ñuble region, about 500km (300 miles) south of Santiago, the capital.
