SYDNEY, Australia: Fanned by the hottest temperatures on record, a series of wildfires tore through southern Australia over the weekend, killing at least 131 people in the deadliest natural disaster on record, police said Monday. Forensic investigators descended on the fire zone Monday to begin identifying bodies found in the rubble. Police warned the death toll could rise. Officials suspect that some of Saturday's fires were set deliberately. Huge tracts of land were declared crime scenes and police announced a special task force to hunt suspected arsonists, who could face murder charges. A man and a boy were charged with lighting fires on the outskirts of Sydney in two unrelated cases on Monday. Again and again, survivors of the that ripped across the southern state of Victoria on Saturday told the same story
