SYDNEY: Australia’s prime minister called up about 3,000 reservists on Saturday as the threat of wildfires escalated in at least three states, while strong winds and high temperatures were forecast to bring flames to populated areas including the suburbs of Sydney.

Prime Minister Scott Morrison said 23 people had died in the wildfires so far this summer, including two in a blaze on a highway on Kangaroo Island off the coast of South Australia state, the latest fatalities.

“We are facing another extremely difficult next 24 hours,” Morrison said at a televised news conference. “In recent times, particularly over the course of the balance of this week, we have seen this disaster escalate to an entirely new level.”

He also confirmed that his scheduled visits to India and Japan later this month have been postponed. He was due to visit India from Jan. 13 to 16 and Japan immediately afterward. Morrison came under fire for taking a family vacation in Hawaii as the wildfire crisis unfolded in December.

He said that the governor-general had signed off on the calling up of reserves “to search and bring every possible capability to bear by deploying army brigades to fire-affected communities.”

Defense Minister Linda Reynolds said it was the first time that reservists had been called up “in this way in living memory and, in fact, I believe for the first time in our nation’s history.”

The government has committed 20 million Australian dollars ($14 million) to lease four fire-fighting aircraft for the duration of the crisis, and the helicopter-equipped HMAS Adelaide was deployed to assist evacuations from fire-ravaged areas.

The fire danger increased as temperatures rose to record levels across Australia on Saturday, surpassing 43 degrees Celsius (109 Fahrenheit) in Canberra, the capital, and reaching a record-high 48.9 C (120 F) in Penrith, in Sydney’s western suburbs.

As night approached, 3,600 firefighters were battling blazes across New South Wales. Power was lost in some areas as fires downed transmissions lines, and residents were warned that the worst may be yet to come.

“We are now in a position where we are saying to people it’s not safe to move, it’s not safe to leave these areas,” state Premier Gladys Berejiklian told reporters. “We are in for a long night and I make no bones about that. We are still yet to hit the worst of it.”

The deadly fire on Kangaroo Island broke containment lines Friday and was described as “virtually unstoppable” as it destroyed buildings and burned through more than 14,000 hectares (35,000 acres) of Flinders Chase National Park. While the warning level for the fire was reduced Saturday, the Country Fire Service said it was still a risk to lives and property.
