North Korea Threatens Nuclear Missile Tests
North Korea threatened Wednesday to conduct nuclear and missile tests and start an uranium-enrichment program in addition to its existing plutonium-based one, unless the U.N. apologizes for criticizing its recent rocket launch, dramatically raising its stake in the worsening standoff over its atomic programs.Pyongyang's Foreign Ministry said in a statement the country "will be compelled to take additional self-defensive measures" unless the U.N. Security Council apologizes immediately. "The measures will include nuclear tests and test-firings of intercontinental ballistic missiles."
