US President-elect Donald Trump accused California officials on Sunday of incompetence over their handling of deadly wildfires raging around Los Angeles.

"The fires are still raging in LA. The incompetent pols (politicians) have no idea how to put them out," Trump said on his Truth Social platform.

"This is one of the worst catastrophes in the history of our Country. They just can't put out the fires. What's wrong with them?" he wrote.
