Australian PM Unveils New Anti-Terrorism Strategy

Australian Prime Minister Tony Abbott has announced new anti-extremism measures to fight the growing threat of terrorism.

"The terrorist threat is rising at home and abroad and it's becoming harder to combat," Abbott told his nation Monday.

The plan includes steps to strengthen immigration laws and crack down on groups that incite hatred.

"We cannot allow bad people to use our good nature against us," he said. "The government will develop amendments to the Australian Citizenship Act so that we can revoke or suspend Australian citizenship in the case of dual nationals."

The move comes after a terrorist took over a cafe in Sydney in December, killing two civilians after a 16-hour hostage standoff.

That terrorist was well known to authorities as an outspoken Muslim who had shown public support for ISIS.

As he ramps up his country's prevention efforts, Abbot is using the phrase "violent extremism" just like President Barack Obama, but he's also calling out Muslims to take a stand against terrorism.

"Now, I've often heard Western leaders describe Islam as a 'religion of peace.' I wish more Muslim leaders would say that more often, and mean it," he said.

Abbott said the Aussie government will take action against hate preachers who advocate terrorism. Immigration authorities will be required to consider an accused person's links with jihadist groups or violent extremism.
