Seoul: Delivering a lecture in Seoul, South Korea's Unification Minister Hong Yong-Pyo has flagged his government`s concern over North Korea going ahead with another nuclear test.
Minister Pyo highlighted the fact that North Korea has conducted four nuclear tests and may soon go ahead with a fifth nuclear detonation, the Xinhua news agency reports.
North Korea also known as DPRK was widely expected to carry out another nuclear test before or after the historic Workers' Party of Korea (WPK) congress that lasted for four days through May 9.
South Korea's military claimed that the DPRK had already completed preparations for another atomic bomb test at its main Punggye-ri nuclear test site in northeastern DPRK where the country conducted all of its four nuclear detonations.
