The Islamic State group says one of its fighters carried out a knife attack in Melbourne in which one man died and two were wounded, the group's Amaq news website has reported.
It provided no evidence for the claim.
Victorian police say a man known to them and federal intelligence authorities parked a ute in Bourke Street just after 4pm on Friday and stabbed three people, one of whom died at the scene.
The attacker was shot as he tried to stab two officers and died later in Royal Melbourne Hospital.
"We are treating this as a terrorism incident," Victoria Police Chief Commissioner Graham Ashton said on Friday night.
