If the United States truly desires dialogue with North Korea, it would lift sanctions against it, according to North Korea's top military body in a statement released on Thursday. North Korea threatened 'the sledge-hammer blow of our army and the people' if its demands are not met.
North Korea demanded on Thursday the removal of U.N. sanctions imposed for its nuclear and missile tests and a U.S. pledge not to engage in "nuclear war practice" with South Korea if Washington truly sought dialogue.
