Australia fears fresh attacks as Sydney mourns siege victims

Sydney

AUSTRALIAN Prime Minister Tony Abbott on Tuesday warned of heightened "terrorist chatter" in the aftermath of the fatal Sydney cafe siege and said that another attack was likely, as tearful mourners paid tribute to the victims.

Iranian-born gunman Man Haron Monis, who had a history of extremism and violence, took 17 hostages in the city's financial heartland last week, unveiling an Islamic flag and demanding to talk to Mr Abbott.
