United Nations Secretary-General Antonio Guterres has condemned North Korea's nuclear test as "profoundly destabilizing" for regional security. He urged Pyongyang to halt such acts. <br/><br/>Mr Guterres said in a statement today, the act is yet another serious breach of the DPRK's international obligations and undermines international non- proliferation and disarmament efforts. <br/><br/><br/>The General Secretary called on Pyongyang to cease such acts and to comply fully with its international obligations. UN Security Council resolutions bar North Korea from carrying out nuclear and missile tests.<br/>
