Sydney Seige: PM Tony Abbott joins tearful Australians in laying flowers at memorial

Tearful Australians laid mounds of flowers at the site where a gunman held hostages for 16 hours at a popular Sydney cafe. The siege ended early Tuesday with a barrage of gunfire that left two hostages and the Iranian-born gunman dead, and a nation that has long prided itself on its peace rocked to its core.Prime Minister Tony Abbott joined the outpouring of national mourning and laid a bouquet at Martin Place, the plaza in Sydney's financial and shopping district where the crisis occurred that has since become the site of a makeshift memorial.
