North Korea warns US that joint military activity with South Korea would lead to nuclear disaster

[Disir]

MALAYSIA has dramatically prevented North Korean diplomats from leaving the country because they say Pyongyang has “manipulated” the murder case involving the death of the leader of the reclusive state Kim Jong Un’s half brother.

Malaysia banned North Korean Embassy officials and staff from leaving on Tuesday, soon after North Korea barred all Malaysians from exiting that country. Relations between the countries have been disintegrating since Kim Jong Nam was attacked with a nerve agent at a Kuala Lumpur airport terminal February 13.

...The further deterioration between the countries came as North Korea warned that US-South Korean military exercises, which it called “the most undisguised nuclear war manoeuvres,” are driving the Korean Peninsula and northeast Asia toward “nuclear disaster.”

North Korea’s UN Ambassador Ja Song Nam said in a letter to the UN Security Council that the US is using nuclear-propelled aircraft carries, nuclear submarines, nuclear strategic bombers and stealth fighters in the joint exercises that began on March 1.
