WASHINGTON (Reuters) - Guam posted emergency guidelines on Friday to help residents prepare for any potential nuclear attack after a threat from North Korea to fire missiles in the vicinity of the U.S. Pacific territory.

Pyongyang's state-run KCNA news agency said on Thursday its army would complete plans in mid-August to fire four intermediate-range missiles over Japan to land near Guam as North Korea and the United States engaged in increasingly heated rhetoric this week over the North's nuclear weapons programme.
