Pyongyang said Tuesday it would scrap the armistice ending the 1953 civil war and sever a military hotline with the US if South Korea and Washington went through with planned two-month joint war games. The threats came as the US and China were said ready to approve a UN Security resolution on sanctions for North Korea’s third nuclear test last month. “We will be suspending the activities of the KPA representative office at Panmunjom truce village…” the negotiating body for enforcing the armistice, said the North Korean government spokesman.
