N. Korean Authorities Urge Civilians to Evacuate Near Site of Possible Nuke Test

"Reports from Seoul Korea, (daily newspaper Joongang Ilbo in Seoul) via the Japanese Jiji press agency, that South Korean intelligence has intercepted radio messages/communications in North Korea, which were aired last month, to civilians in the Kilju County, Northern Hamgyeong Province area of northeastern D.P.R.K., to evacuate.

The source in the South Korean government said "our interpretation is that following North Korea's underground nuclear blast test, they wish to head off any escape of radiation that would be a threat to the nearby civilian population and are evacuating as such."
