Australian leader: Terrorism is greatest security challenge
SYDNEY - Australia's prime minister told an Asia-Pacific regional conference on Thursday that terrorism was a modern form of treason and the region's greatest security challenge.
Prime Minister Tony Abbott gave an opening address to delegates from about 30 countries attending a conference in Sydney on countering terrorism propaganda and enhancing regional cooperation.
He said Australia was "looking at what can be done to deal with Australian citizens who have betrayed our country by fighting with terrorists, this modern form of treason."
