Media: Gunmen take hostages in Sydney cafe
Australian media have reported that hostages are being held in a cafe in one of Sydney's main business areas.
Live television footage on Monday showed patrons inside a cafe near the New South Wales state parliament with their hands pressed against the windows.
As many as 20 people are reported to be in the cafe, and there are at least two gunmen inside, witnesses said. Police said an operation was underway.
Witnesses also reported hearing loud bangs at the scene.
A black and white flag, similar to those used by "Islamic State" militants, could also be seen in the window.....
