North Korea May Have More Nuke Test Sites

The ROK intelligence leak ticker reports:

North Korea may have built more underground nuclear test sites in the northeastern district where it staged its first two tests, a news report has said.

South Korean intelligence sources quoted by Yonhap news agency said the North could have built two or three such sites in and around Punggyeri in Kilju district near the coast. [AFP]

I wonder how many concentration camp prisoners are entombed in those new sites.
