United Nations Secretary General Ban Ki- moon speaks to the press at the UN New York January 6, 2016 before a Securty Council meeting about North Korea claiming  it had successfully tested a hydrogen bomb.Ban issued a strong condemnation of North Korea's nuclear test and called on Pyongyang to halt its nuclear program. "I condemn it unequivocally. I demand the DPRK cease any further nuclear activities," Ban told reporters ahead of an emergency meeting of the UN Security Council. North Korea said it had carried out a "successful" miniaturized hydrogen bomb test -- a shock announcement that, if confirmed, would massively raise the stakes in the hermit state's bid to strengthen its nuclear arsenal.
