PERTH, Australia — Firefighters battled two wildfires in Western Australia today, water bombing them from above as they tried to stop their spread. The two blazes have razed 4,000 acres of forested land to the north and southeast of Perth since Saturday.

In Roleystone and Kelmscott, at least 41 houses were destroyed and another 19 damaged, Craig Hynes, chief operations officer for the Fire and Emergency Services Authority, told reporters.

A firefighter who was injured fighting that blaze, which erupted shortly before noon Sunday, was in stable condition.

Farther north, in the Swan Valley district, some 150 firefighters using water-bombing helicopters and trucks had contained another fire by early today. There was no property lost there.
