The nuclear detonation device test comes as North Korea prepares for its first nuclear test in nearly five years, according to the Yonhap News Agency. A South Korean presidential official confirmed the detonation test on Wednesday. A full-blown nuclear test would be the seventh in North Korea’s history.
Kim Tae-hyo, first deputy director of South Korea’s National Security Office, told reporters that he believes the nuclear test will not happen in the next couple of days, but that it could “certainly” take place after that, according to Yonhap News Agency.
The launch was the 17th test North Korea has conducted this year, according to Yonhap News Agency.
The missiles are presumed to be intercontinental ballistic missiles, according to the report.
