ISIS? have Hostages in Sydney Australia Cafe, force them to hold up ISIS sign

Cafe Worker and  Cafe customer have  hands pressed against the Window holding up sign

Hostages were being held inside a central Sydney cafe where a black flag with white Arabic writing could be seen in the window, local television showed on Monday, raising fears of an attack linked to Islamic militants.

Australia, which is backing the United States and its escalating action against Islamic State in Syria and Iraq, is on high alert for attacks by radicalized Muslims or by home-grown fighters returning from fighting in the Middle East.

Part of Martin Place, home to the Reserve Bank of Australia, commercial banks and close to the New South Wales (NSW) state parliament, was closed off by armed police.

Live television footage showed patrons inside a cafe standing with their hands pressed against the windows. A black and white flag similar to those used by Islamic State militants in Iraq and Syria was also visible.

NSW Police tweeted: “A police operation is underway in Martin Place, Sydney’s CBD. People are advised to avoid the area.”

Dozens of police including a SWAT team were setting up and a couple of hundred people were being held back by cordons.

Trains and buses were stopped and roads were blocked in the area, with train operators saying there had been a bomb threat at Martin Place.

Update 7:03 PM EST: 
There are 13  hostages in the cafe.  The count includes employees and customers. At approximately 9:44 AM, a man carried  a blue bag into the busy Sydney cafe and told the people behind the counter that he had a gun. The doors to the cafe were then locked by a second Islamic terrorist. The flag which the hostages are holding  up appears similar to the ISIS flag however it is a Shahadah flag which states that Allah is the only ruler. This has been ruled as an act of terror.
