UNITED NATIONS, Feb. 12 (Xinhua) -- The UN Security Council met behind closed doors Tuesday morning in an emergency session on the latest nuclear test conducted by the Democratic People's Republic of Korea (DPRK).
South Korea, which holds the rotating council presidency for February, called the meeting.
UN Secretary-General Ban Ki-moon has condemned the test, saying it is "a clear and grave violation" of the relevant Security Council resolutions.
In a statement issued here by his spokesperson early in the day, Ban said "it is deplorable that Pyongyang defied the strong and unequivocal call from the international community to refrain from any further provocative measures."
"The secretary-general is gravely concerned about the negative impact of this deeply destabilizing act on regional stability as well as the global efforts for nuclear nonproliferation," said the statement.
Ban once again urged the DPRK to reverse course and work toward denuclearization of the Korean peninsula.
According to the statement, the UN chief has repeatedly called on the new leadership in Pyongyang to address international concerns and start building confidence with neighboring countries and the international community.
The statement added that the secretary-general is confident that the Security Council will remain united and take appropriate action, while he "remains in close contact with all concerned parties and stands ready to assist their efforts."
