2014 Sydney hostage crisis
After the siege began, a staged exclusion zone was established with thousands of people evacuated from nearby buildings, including from the floors above the café. The Sydney Opera House was evacuated after a suspicious package was found; however, reports were unconfirmed by police. The US Consulate General in Sydney, located in Martin Place, was also evacuated. Some Sydney schools were put in "white level lockout" due to the hostage situation, which meant that no school group was permitted to leave the school grounds.
Man Haron Monis
Man Haron Monis, born Mohammed Hassan Manteghi Borujerdi (19 May 1964 – 16 December 2014), was an Iranian-born refugee and Australian citizen who took hostages in a siege at the Lindt Chocolate Café at Martin Place, Sydney on 15 December 2014, lasting for 17 hours, until the early hours of the following morning. The siege resulted in the death of Monis and two hostages.
