SourceSydney siege: Five emerge from Martin Place Lindt cafe, unknown number of hostages still held by 'armed offender'
Five people have been seen running from a cafe at the centre of a siege involving an unknown number of hostages in the heart of Sydney's CBD.
An armed man entered the Lindt cafe in Martin Place before 10:00am (AEDT) and has held staff and customers hostage all day.
New South Wales Deputy Police Commissioner Catherine Burn said police were negotiating with the man.
"We have the best negotiators in the world and we are working through this methodically to make sure that nobody is injured," she said.
She said the five hostages who emerged from the cafe were being assessed to ensure they were in good health and were being spoken to by police.
She declined to say whether the hostages had escaped or been released.
Just before 4:00pm, two men were seen running out a front door of the cafe, one with his arms in the air.
A man wearing a Lindt apron also ran from a side door that was surrounded by heavily armed police.
About an hour later, two female cafe workers were seen running from the building.
One, wearing an apron, ran into the arms of a police officer outside.
Police have identified the gunman and he is understood to be known to them.
The ABC is among numerous media outlets to have been contacted by hostages at the hostage taker's request.
Police have asked media not to broadcast details about the phone calls or to identify the man.
A man wearing a backpack and bandana, and waving what appeared to be a gun, could be seen directing hostages inside the cafe.
At one point, he appeared to use a hostage as a human shield as he moved through the building.
This evening, NSW Police Commissioner Andrew Scipione said the police focus was on getting the hostages out safely.
"Our plan, our only goal tonight and for as long as this takes, is to get those people that are currently caught in that building, out of there safely," he said.
"That remains our number one priority and nothing will change."
Earlier, Deputy Commissioner Burn said she could not confirm how many people were being held hostage, but police believed it was fewer than 30.
She said people still inside buildings in Martin Place should stay indoors.
"Police will advise you as we go along," she said.
Hostages were seen pressing a black flag displaying Arabic text against the cafe window soon after police were called to the busy pedestrian thoroughfare.
The text on the flag said: "There is no God but Allah and Muhammad is the messenger of God."
NSW Health confirmed one of the hostages was in a satisfactory condition after being treated at St Vincent's Hospital.
Some mosques, synagogues and churches are holding prayer vigils in Sydney and other Australian cities this evening.
This morning, emergency crews used ladders to evacuate people, including a baby, from upper levels of the building.
Hundreds of officers, many of them heavily armed and wearing body armour, took up positions in the area and several surrounding blocks were cleared.
Prime Minister Tony Abbott made a brief statement after chairing Cabinet's national security committee meeting this evening.
"It is profoundly shocking that innocent people should be held hostage by an armed person claiming political motivation," he said.
"Nevertheless, I can say that NSW Police and other agencies have responded to this incident with great professionalism.
"Yes, it has been a difficult day. Yes, it is a day which has tested us, but so far like Australians in all sorts of situations, we have risen to the challenge."
Earlier, 702 ABC Sydney's John Donegan said police were using ladders propped against awnings to evacuate people through windows from floors above the cafe.
"They have got a series of small ladders up onto awnings and into windows," he said.

"I've seen three or four people coming out. It's a very slow operation."
Staff from the Seven Network have been allowed back into their Martin Place headquarters, after the building was earlier evacuated and taken over by tactical response police.
Reporter Chris Reason told 702 ABC Sydney that staff inside the Seven building had tried to count the number of people in the cafe, and estimated 15 people were taken hostage before five ran free this afternoon.
"There are older people, young, male, female, but fortunately no children," he said.
"I've seen plates of food delivered to hostages by Lindt staff.
"That's important, because it's showing some humanity."
He said Channel Seven staff saw the armed man shouting at hostages after some of them ran out of the building.
Earlier, Seven producer Patrick Byrne said staff at the network watched the situation unfold before they were evacuated.
"We raced to the window and saw the shocking and chilling sight of people putting their hands up against the panes of glass at the cafe," he said.
"This was just extraordinary.
"Then, as we were looking wondering what was going on, it seemed to be like an armed hold-up, more police arrived at Martin Place.
"The area was cleared. People were kept back.
He said "gasps went through the newsroom" as the black flag was placed against one of the windows.

A man at the scene told ABC News he saw a woman try to enter the cafe before she reported seeing a man inside with a gun.
"There was a bit of a kerfuffle and the next thing she said, there was a blue bag, and she said 'there's a gun in the bag', and then the commotion started.
"She told everyone to get going and we're running out of the building."
Martin Place worker Josh Acton said he was outside smoking when police suddenly ordered him inside a building, where about 80 people were taking cover.
"We're on tenterhooks," he said.
"We have grouped around people's computers to watch the news come in to see if there's any further updates.

Elleanor Gillard, who works in another part of the building, said police had told them to stay inside and away from the doors.
"We've just been notifying everyone on the floors above - I'm on the ground - not to come down in the lift because the lifts open up right in the foyer between us and Lindt [cafe]," she said.
She said she saw a look of terror on the faces of two hostages who appeared to have been forced up against the glass.
"I'm just thinking about the guys in Lindt - the people we see everyday, go in and buy our coffee from them - and I'm sure they're terrified. It must be horrible for them."
In a statement posted on Facebook, Lindt Chocolate Cafe Australia expressed its concern and thanked the public for its support.

The president of the Lebanese Muslim Association, Samier Dandan, said Australian Muslim leaders were in talks to see if the community could help.
He said it was not known who was behind the siege and whether there were any links to the Australian Muslim community.
"Whether he is someone who belongs to the Australian Muslim community or not, we are still waiting for information to be provided by police, and based on that if there's something the Muslim community can do or assist, we are there."
The director of the Global Terrorism Research Centre, Professor Greg Barton, said the black flag was clearly meant to signify a link with a terror group, possibly the Islamic State.
"It's likely a link with its groups, and what's happening in Syria, rather than a statement of faith," he told 702 ABC Sydney.
"But it could also be a single lone wolf attacker."

The UN Alliance of Civilisations' Aftab Malik, a scholar-in-residence at Sydney's Lebanese Muslim Association, said the flag had been misappropriated by extremist groups.
"The Shahadah [phrase on the flag] literally means the testimony of faith and Muslims believe it is a transcendental truth," he said.
"We're seeing a branding war taking place amongst various extreme groups, Jabhbat al-Nusra, Al-Qaeda and the offshoots, and now we have ISIS.
"They're using very powerful spiritual realities and being misappropriated for their misguided political agendas."
People seeking more information about the incident, including about government services, can call the Public Information Inquiry Centre on 1800 227 228.
