SYDNEY (AP) — A Sydney shopping mall opened to the public on Thursday for the first time since a mass stabbing i n which six people died, while the Australian prime minister raised giving citizenship to an immigrant security guard who was wounded while confronting the knife-wielding attacker.

The deadly rampage through Westfield Bondi Junction on Saturday was the earlier of two knife attacks by lone assailants over three days that have traumatized Sydney.

The man who stabbed 18 people in Saturday’s attack was shot dead by police. A 16-year-old boy is in police custody after he allegedly stabbed a Christian bishop and priest during a church service on Monday. Police allege the boy had a religious or ideological motivation and attacked during the streamed service to cause intimidation.

Prime Minister Anthony Albanese has praised those who intervened in Saturday’s attack to prevent more deaths, including security guard Muhammad Taha, who was stabbed in the stomach. Taha is from Pakistan and working in Australia on a temporary visa that is due to expire within weeks.
