Not sure about the source, but oh well:

North Korea has started digging tunnels at its nuclear test site in apparent preparation for a third atomic detonation, a report said on Sunday.


The North started building at least two new tunnels at its Punggye-ri facility in northeastern North Hamgyong province for a possible underground atomic test, Yonhap news agency said, citing a senior Seoul official.


The report comes after Pyongyang racked up tensions at the end of last year by launching an artillery barrage against a South Korean island and disclosing a new nuclear programme, before going on a charm offensive last month.

If they do go ahead with another nuclear test it really doesn't help tensions, but S.Korea aren't likely to respond directly.

Confirmed, sort of.

North Korea is excavating new tunnels at the site where it previously carried out two nuclear test detonations, raising concerns that a third blast could be in the works, Reuters reported on Sunday (see GSN, Feb. 18).

An anonymous South Korean official told the Yonhap News Agency that North Korea was digging multiple tunnels prior to choosing which one to use for another nuclear test.

"South Korean and U.S. intelligence authorities have spotted North Korea building several other underground mines at Punggyeri where it had run two nuclear tests," the government source said. "It is judged to be clear evidence of preparing for a third nuclear test."
