At this hour, a gunman has taken at least 13 people hostage in a Sydney cafe. The gunman has forced several of the captives to hold a black Islamic flag, possibly an ISIS flag.
Hopefully authorities can bring the hostages to safety and detain the gunman. That might be difficult if the gunman is on a suicide mision and plans to take as many people with him as he can.
UPDATE: The standoff continues, but five of the hostages managed to escape. The gunman claims he has bombs distributed throughout the city and is demanding an ISIS flag and a phone call from Australian Prime Minister Tony Abbott.
