AUSTRALIA-ATTACKS-CRIME

Royal Australian Navy Anzac-class frigates, the HMAS Stuart (FFH 153), at right, and the HMAS Warramunga (FFH 152), at left, are seen moored at Sydney's Garden Island naval base after two men were arrested on December 23, 2015 during a counter-terrorism operation in Sydney, with the key Australian naval base among locations they were allegedly targeting, police said. Their arrests are part of Appleby, a rolling operation investigating people suspected of being involved in domestic acts of terrorism, Australians fighting in Syria and Iraq and the funding of terrorist organisations.
