Hundreds of firefighters and soldiers backed by seven helicopters and five water-dropping planes were fighting the blaze which broke out on Monday near the village of San Xoan de Laino in the northwestern region of Galicia, the regional government said in a statement.
Officials evacuated two schools in the area on Tuesday because of the advancing flames but the blaze was no longer threatening built-up areas, it added.

A spark from a high-voltage power line is the “most probable” cause of the wildfire, which was then fuelled by strong winds, the vice president of the regional government of Galicia, Alfonso Rueda, told local television.
Authorities in Galicia estimate the blaze has so far ravaged around 850 acres (2,100 acres) of land, making it the worst wildfires since deadly blazes hit the region in October 2017.

Firefighters said lighter winds had helped them get the upper hand against the blaze although they cautioned temperatures remained high.
