CANBERRA, Sept. 11 (Xinhua) -- Australia can't rest easy and a surprise terror attack could happen at any time, Foreign Minister Bob Carr warned Tuesday.
"We can't rest for a moment. The threat is real," Carr told ABC Television as the Unite States mark the 11th anniversary of the 9/ 11 attacks.
"We can't rest easy. We have achieved the appropriate balance in this country between alertness to the threat and respect for civil liberties," he said. "I live and our security people live with the reality that a surprise strike could come at any time."
Carr said that the world needs to worry about the ultimate threat of terror groups using fissile material to detonate a backpack or suitcase nuclear bomb in a major capital.
