Australia is mourning the deaths of a woman and her three children who were "senselessly murdered" in a car fire, Prime Minister Scott Morrison has said.
Police are yet to confirm reports the father, ex-rugby player Rowan Baxter, set the car alight in Brisbane before stabbing himself to death.
However, they confirmed a history of family violence. Hannah Baxter, 31, and her children were killed on Wednesday.
The case has sparked national outcry over domestic violence.
