Australia wildfires slowly being controlled

The wildfires that have roared through southeast Australia for nearly a week were slowly coming under control today, as investigators continued the search for who may have set some of the deadly blazes.

The Country Fire Authority said the number of fires burning had dropped to 21 from about 35 on Thursday. While "the threat will remain for weeks to come", a spokesman said no towns were under threat today morning and that good weather had allowed firefighters to build containment lines around the fires.

Meanwhile, more than 150 detectives were working on an arson investigation, authorities said.

Two men who were arrested for "suspicious behavior" on Thursday were released without charges.

"We are satisfied with their explanation and don't expect to talk to them again," Victoria state police inspector Peter Sheppard said.

Firefighters have battled blazes since Saturday, including several new fires that broke out on Tuesday night, which officials said almost certainly were the result of arson.u00a0

The official death toll from the fires has remained at 181 for the past two days. But government officials say that number could reach as high as 300 based on the number of people missing and number of homes destroyed.

Sheppard said the tally is not being updated as frequently because it's become harder to verify fatalities from the fires -- which have destroyed more than 1,800 homes and displaced about 7,000 people.

"Initially it was a fairly straitforward process -- bodies were in cars, on sides of roads," he said. "Now, the search is through buildings. Many have collapsed."u00a0

Yesterday, Prime Minister Kevin Rudd announced that the government would hold a memorial service and national day of mourning for victims of the fires. He said the government is working with the nation's Council of Churches to determine the day.
