North Korea has reacted angrily to reports of new sanctions over its latest nuclear weapon test.
It promised to cancel the 1953 ceasefire that ended the Korean War, citing the US-led push for new measures against it.
Its Korean People’s Army Supreme Command warned of stronger additional counter-measures in a statement that came amid reports that Washington and North Korean ally Beijing have approved a draft of punishing sanctions for a UN Security Council resolution.
The United States and others worry that North Korea’s third nuclear test pushes it a step closer toward its goal of having nuclear-armed missiles that can reach America, and condemn its rocket launches and nuclear tests as a dangerous threat to regional security.
North Korea says its nuclear programme is a response to US hostility that dates back to the 1950-53 Korean War, which ended with an armistice, not a peace treaty, leaving the Korean Peninsula still technically in a state of war.
North Korea warned it will cancel the Korean War ceasefire agreement on March 11, citing US-South Korean military drills that began March 1.
North Korea said Washington and others are going beyond mere economic sanctions and expanding into blunt aggression and military acts.
North Korea also warned that it will block a communications line between it and the United States at the border village separating the two Koreas.
