Abbott signals further terror laws in looming crackdown

Tony Abbott has signalled a new crackdown on extremist organisations.

The prime minister says the government has to take on the groups that justify terrorism and act as its recruiting agents, such as the notorious Hizb ut-Tahrir Islamists.

"If cracking down on Hizb ut-Tahrir and others who nurture extremism in our suburbs means further legislation, we will bring it on and I will demand that the Labor Party call it for Australia," he said during a speech in Canberra on Monday.
