Australian Prime Minister Malcolm Turnbull said on Tuesday (6 June) that police were treating a deadly siege in the southern city of Melbourne as an "act of terrorism" in which a gunman was killed. The Islamic State (Isis) militant group has claimed responsibility for the attack, saying the gunman was one of its soldiers.
A day earlier, on Monday, the attacker, identified as Yacqub Khayre, 29, held a woman hostage inside an apartment building in Melbourne. While the hostage was rescued unharmed, three police officers suffered injuries when they engaged in a firefight with Khayre.
The attacker was shot dead by police.
A man was found dead in the foyer of the building where Khayre held the woman against her will.
