At least one gunman has taken several people hostage at a cafe in the Australian city of Sydney.

Pictures on Australian television show at least three people with their hands up against a window, and a black flag with Arabic writing.

Hundreds of armed police have sealed off Martin Place in Sydney's central business district.

New South Wales police have asked people to avoid the area.

I wonder who it could be

Fortunately my Dad didn't go into work today.
