SYDNEY (AP) A father and son who were battling flames for two days are the latest victims of the worst wildfire season in Australian history, and the path of destruction widened in at least three states Saturday due to strong winds and high temperatures.

The death toll in the wildfire crisis is now up to 23 people, Prime Minister Scott Morrison said after calling up about 3,000 reservists to battle the escalating fires, which are expected to be particularly fierce throughout the weekend.
