More warnings and threats between US, North Korea

The United States defence secretary has warned North Korea it is risking the destruction of its people, saying it is ''grossly" outmatched in any conflict between the two countries. The comments by Jim Mattis come as US secretary of state Rex Tillerson has tried to calm fears over the crisis. North Korea says it will complete plans to attack waters near Guam by mid-August and will await its commander-in-chief's order. Prime Minister Malcolm Turnbull says he will invoke the ANZUS Treaty and Australia will come to the aid of the United States if North Korea attacks.
