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.
History of Sydney
From 1788 to 1900 Sydney was the capital of the British colony of New South Wales. An elected city council was established in 1840. In 1900, Sydney became a state capital, when New South Wales voted to join the Australian Federation. Sydney today is Australia's largest city and a major international capital of culture and finance. The city has played host to many international events, including the 2000 Summer Olympics.
