SEOUL- North Korea has completed preparations for another nuclear test, South Korea's Yonhap News Agency reported on Monday, citing South Korean government sources who said the North may use a previously unused tunnel at its mountainous test site.
Pyongyang on Friday set off its most powerful nuclear explosion to date, saying it had mastered the ability to mount a warhead on a ballistic missile and vowing to continue strengthening its nuclear power.
