North Korea has confirmed its intention to carry out a third nuclear test, saying it is the “demand of the people.” It comes after the UN tightened sanctions against the regime, following its December long-range rocket launch. "The people's demand is that we must do something even greater than a nuclear test. The United Nations Security Council has left us with no other options. We have no other ways but to push forward to the final showdown," Rodong Sinmun, the official daily newspaper of the ruling communist party, wrote in a commentary on Saturday.
