An emergency patrols a fire Saturday in the Gippsland region in Australia's Victoria state.
Witnesses described seeing trees exploding and skies raining ash as temperatures hit a record 117 degrees Fahrenheit on Saturday in Victoria state and combined with raging winds to create perfect conditions for uncontrollable blazes.
"Hell in all its fury has visited the good people of Victoria in the last 24 hours," Prime Minister Kevin Rudd told reporters today as he toured the fire zone.
Police said they believed the deaths included groups of people whose charred bodies were found in cars -- suggesting families or groups of friends were engulfed in flames as they tried to flee. One official said an entire town had been razed save for one building, though no deaths were reported there.
Police said they were still trying to confirm details of the deaths, with officers' movements hampered by still-dangerous conditions in the disaster zone.
But Victoria police spokeswoman Sarah Campbell said a total of 35 bodies were found at a dozen locations north and east of the state capital, Melbourne. At least 18 people were hospitalized with burns.
Conditions in Victoria eased today, but several major fires were still posing a threat and state Premier John Brumby said troops would be deployed to help thousands of exhausted volunteer firefighters battle on.
The fires were so massive they were visible from space Saturday. NASA released satellite photographs showing a white cloud of smoke across southeastern Australia.
Deputy Commissioner Kieran Walshe said police suspected some of the fires were set deliberately, and predicted it would take days to get all the blazes under control.
The largest of about a dozen big fires in Victoria ripped unchecked across at least 115 square miles (298 square kilometers) of forests, farmland and towns north of Melbourne on Saturday.
"The whole township is pretty much on fire," Peter Mitchell, a resident of the town of Kinglake, where at least six people died in the same car, told Australian Broadcasting Corp. radio during the inferno. "There was no time to do anything. ... It came through in minutes."
Marysville, a former goldrush town of about 800 people 60 miles (100 kilometers) northeast of Melbourne, was almost completely gone, a local lawmaker said. Media reports said residents fled to a football field to escape the flames.
"I understand, there's only one building left in the town," said federal parliamentarian Fran Bailey.
"It's been, I think, the worst day in our history," said Brumby, whose parents' house was among those saved by firefighters Saturday.
Forecasters said temperatures would only reach about 77 F (25 C) on Sunday around Melbourne, but along with cooler conditions came wind changes that could push fires in unpredictable directions.
On Saturday, steel-gray smoke clogged the air and flames roared to two-story heights, while homes and businesses burned.
In the town of Taralgon, resident Lindy McPhee watched in fear as a fire front edged closer to the town until rain began falling late Saturday.
"It's raining black soot," McPhee told Sky News television.
In nearby Wittlesea, Sally Tregae described feeling terror as the fire approached.
"I saw trees explode in front of me," she said. "It's a horrible thing to see."
Rudd said he was "absolutely horrified" by the disaster and promised blankets for victims in the near term and money for them later.
Victoria's Country Fire Authority deputy chief Greg Esnouf said Saturday's conditions were "off the scale" in terms of danger. Another fire official, Stuart Ord, said some 460 square miles (1,190 square kilometers) was burned by early Sunday, and estimated the number of houses destroyed would be "into the hundreds."
In New South Wales state, where several fires were also burning but not posing an immediate threat to property, police detained and questioned a man in connection with a blaze but released him without charge.
Wildfires are common during the Australian summer. Government research shows that about half of the roughly 60,000 fires each year are deliberately lit or suspicious. Lightning and people using machinery near dry brush are other causes.
Australia's deadliest fires were in 1983, when blazes killed 75 people and razed more than 3,000 homes in Victoria and South Australia.
