A "radicalised" teenage boy has been shot by police in Perth after he stabbed a man with a kitchen knife.
Australian police say they received a call from the youth just after 10pm on Saturday, who said he was "going to commit acts of violence", Western Australia Police Commissioner Col Blanch said at a press conference on Sunday.
Police then received a second emergency call saying "a male with a knife was running around" in a Bunnings carpark, he added.
When officers arrived they found a 16-year-old armed with a large kitchen knife.
"Two officers drew their tasers and one of the officers drew his firearm," Cmmr Blanch told media.
"They challenged the male to put down the knife, which he did not."
He rushed at two of the officers, whose Tasers failed to stop him, and when he advanced on a third officer he was shot, Cmmr Blanch said. He died soon afterwards in hospital.
The stabbing victim is in a serious but stable condition in hospital after suffering a single stab wound in the back.
The youth, who was known to police and had mental health issues, had been part of the state's Countering Violent Extremism program, aimed at deradicalisation.
Speaking at the same press conference, Western Australia Premier Roger Cook said there were indications the youth had been "radicalised online".
"But I want to reassure the community at this stage it appears that he acted solely and alone," Cook said.
"Members of the WA Muslim community, who were concerned by his behaviour, contacted police prior to the incident and I thank them for their help."
Cmmr Blanch said it "has the hallmarks" of a terrorist attack, although it hasn't been labelled one at this stage.
"I believe this is a person acting alone ... I don't need additional capability at this time whilst it meets the criteria, or at least the definition," he said.
"That's something that we can work towards as we find out more information from the motivations behind this."
