Breaking News: North Korea has threatened the South with 'final destruction'.
North Korea has threatened the South with 'final destruction' during a debate at the UN Conference on Disarmament on Tuesday
following an underground nuclear test, Reuters reports.
The North has warned that it could take "second and third steps" after a nuclear test last week.
"As the saying goes, a new born puppy knows no fear of a tiger. South Korea's erratic behavior would only herald its final destruction," North Korean diplomat Jon Yong-ryong was cited by Reuters.
