Forest fires in southern Argentina have scorched¹ more than 15,000 hectares (37,000 acres) this week, authorities said, though rain began falling in parts of Patagonia on Sunday to the relief of residents.

The largest blaze, burning since Monday near the small town of Epuyen in the Andes, has charred² some 11,980 hectares, the Chubut provincial³ fire service said in a statement.

Another fire of unspecified size is burning nearby in the Los Alerces National Park.

Firefighters are also battling to contain another two fires in Chubut and neighboring Santa Cruz provinces that have burned some 3,800 hectares, Argentina's emergency management agency said.
