there aren t clear demands. if he took a situation like this saying i want individuals released from prison and australians brought back, just that he wants an isis flag and a chance to speak to the prime minister is enough to make me question a little bit. so it s 10:00 p.m. in the night in australia right now. we re not showing live pictures of the chocolate cafe where at least 30 people or about 30 people are being held by a gunman because it is an active crime scene. we have on the phone right now, sara james. what can you tell us? at that cafe just a short time ago the lights were turned out by one of the hostages and so the scene is in the dark. it s quite an eerie situation here in the center of the city. we are kept back several hundred yards away.
