 Two hostages also died, while another four people, including a police officer, were injured in the incident.The designation of the 2014 Sydney hostage crisis, also known as the Sydney Martin Place siege, has been subject to debate among terrorism experts and news commentators.Initially, during the early stages of the incident, the Australian government and NSW authorities did not label the event as a terrorist attack; however, as the siege continued, NSW police authorised the engagement of the state's counterterrorism task force, treating the incident as an act of terrorism.
