N.Korea 'Kept Nuclear Scientists out of Foreign Reporters' Way'

North Korea hid nuclear scientists at the test site in Punggye-ri in a hospital before foreign reporters arrived to cover its demolition, Radio Free Asia reported Tuesday.

RFA quoted a source in North Pyongyang Province as saying he was told by a high-ranking official that a large number of nuclear scientists were sent to a hospital run by the General Bureau of Atomic Energy. 

"I was unable to assess how many were admitted," the source said. "The hospital treats technicians and staff at nuclear research facilities, is guarded by armed soldiers and only authorized personnel can enter. The fact that some technicians are staying there with their entire families shows that they are not there to be treated as officials claim, but are being isolated there."

The source said locals think it is a tuberculosis hospital, "but they are not allowed even to pass by the facility, and there is a common awareness that it is a classified military installation."
