Seoul, Apr 8: North Korea might be preparing for its fourth nuclear test, a minister said Monday.
"I can only say that there are such signs (of North Korea's new nuclear test)," Unification Minister Ryoo Kihl-jae told lawmakers at the parliamentary meeting for diplomacy and unification.
His comments came after a lawmaker said there is a rise in movements of personnel and vehicles near the test complex at Punggye-ri, North Hamgyong province, citing unspecified sources.
The lawmaker asked whether the movement was the sign of the fourth nuclear test, reported Xinhua.
North Korea conducted its previous three nuclear tests at the Punggye-ri test site. The latest occurred Feb 12.
Ryoo noted that the question was related to "intelligence" matters and declining to share details.
