At the end of the 16-hour siege of Lindt Cafe in Sydney, three people including the gunman, Lindt manager Tori Johnson and Barrister Katrina Dawsonare were killed.
Five people managed to escape earlier. Heavily armed Australian police stormed the cafe early on Tuesday morning and freed the remaining hostages and ended the siege.
Australian Prime Minister Tony Abbott and many others laid flowers at a makeshift memorial for the victims of the incident that shocked the nation.
Abbott said that the gunman, identified as 50-year-old Man Haron Monis, had "a long history of violent crime, infatuation with extremism and mental instability and was a deeply disturbed individual, but he was not on a terror watch list".
