Sydney, Rabi'I 12, 1436, Jan 3, 2015, SPA -- Thousands of Australians fled their homes as wildfires raged across the nation's south on Saturday, with firefighters struggling to contain the blazes fanned by strong winds. Six homes were destroyed by the fires in South Australia and Victoria states, officials said, though no serious injuries have been reported. Dry conditions and temperatures in the upper 30s Celsius (around 100 degrees Fahrenheit) were causing headaches for firefighters battling the blazes. Officials said it would likely take days to get the fires under control. The worst of the fires was in the Adelaide Hills in South Australia, where the flames had destroyed five homes and put hundreds of others at risk, AP quoted state Country Fire Service spokesman Daniel Hamilton as saying. Residents of 19 communities had been asked to evacuate as a predicted shift in the winds later Saturday prompted fears the flames could worsen. The forecast was also calling for increased humidity, which could slow the fire's progress Saturday night, Hamilton said. Up to 2,000 firefighters were battling the blazes across the state from the ground and the air, with more than a dozen aircraft dumping water onto the flames. Six firefighters were treated for minor conditions, mainly smoke inhalation, Country Fire Service Chief Officer Greg Nettleton said. In neighboring Victoria state, firefighters had controlled more than 300 fires since Friday, with only one still considered a danger. One home was destroyed in the blaze in the western Victoria town of Moyston, state Country Fire Service spokesman Mario Xuereb said. --SPA 14:54 LOCAL TIME 11:54 GMT www.spa.gov.sa/w
