Two hostages (L) run for cover behind a policeman (R) during a hostage siege in the central business district of Sydney on December 15, 2014.
Three people ran out a fire exit of a Sydney cafe where a gunman took an unknown number of people hostage at the height of Monday morning rush hour. Later, two more persons were seen escaping from the Sydney building.
Two other people inside the cafe were seen holding up a flag containing an Islamic declaration of faith.
New South Wales Police Deputy Commissioner Catherine Burn confirmed that the three people "have now emerged from the location" where the hostage crisis had been unfolding for more than six hours.
"The first thing that we are doing is making sure that they are OK. We will then establish who they are and then we will continue to work with them," Burn said.
"We do not have any information that suggests that anybody is harmed at this stage," she added.
The three people were seen on live video footage bolting out of the door of the Lindt cafe past heavily armed police and then disappearing around a corner. The footage showed one of them wore a Lindt apron.
The development came six hours after a gunman entered the Lindt Chocolat Cafe in Martin Place, a plaza in the heart of the city's financial and shopping district that is packed with holiday shoppers this time of year. Many of those inside the cafe would have been taken hostage as they stopped in for their morning coffees.
New South Wales state Police Commissioner Andrew Scipione said police did not know the gunman's motivation and were not sure how many people were being held inside.
"We have not yet confirmed it is a terrorism-related event," Scipione said. "We're dealing with a hostage situation with an armed offender and we are dealing with it accordingly."
Burn said that police negotiators have made contact with the gunman.
Hundreds of police flooded into the area, streets were closed and offices evacuated. The public was told to stay away from Martin Place, home to the state premier's office, the Reserve Bank of Australia, and the headquarters of two of the nation's largest banks. The state parliament house is a few blocks away.
Television footage shot through the cafe's windows showed several people with their arms in the air and hands pressed against the glass, and two people holding up a black flag with the Shahada, or Islamic declaration of faith, written on it.
The Shahada translates as ""There is no God but Allah and Muhammad is His messenger." It is considered the first of Islam's five pillars of faith, and is similar to the Lord's Prayer in Christianity. It is pervasive throughout Islamic culture, including the green flag of Saudi Arabia. Jihadis have expropriated the Shahada in their own black flag.
