SEOUL Jan 23 (Reuters) - North Korea threatened to step up its military push including its nuclear weapons programme after the United Nations Security Council, including its ally China, condemned its December rocket launch.

"We will take measures to boost and strengthen our defensive military power including nuclear deterrence," its Foreign Ministry said in a statement carried by state news agency KCNA.
