Australia boosts parliament security amid attack 'chatter'

Police conducted sweeping anti-terror raids in Sydney on Thursday

Security is being upgraded at the Australian parliament following "chatter" suggesting extremists could target it for attack.

PM Tony Abbot said Australian Federal Police would assume responsibility for security at the site in Canberra.
The move came a day after major anti-terrorism raids took place in Sydney.
They were aimed at thwarting an alleged plan by Islamic State (IS) supporters to carry out killings in Australia, including an on-camera beheading.
In recent weeks, IS - a militant Islamist movement which has seized vast areas of Iraq and Syria - has released video footage showing the beheadings of two American journalists and a British aid worker seized.
