The United Nations Security Council has ordered tougher sanctions against North Korea for its December rocket launch, prompting Pyongyang to defiantly hint at another nuclear test.
The 15-member Security Council on Tuesday voted unanimously to condemn the launch as a ballistic missile test banned under existing U.N. sanctions. It also threatened to take "significant action" if Pyongyang conducts more launches or tests.
North Korea responded immediately, saying it would hold no more talks on de-nuclearization. It also vowed to boost its military and "nuclear deterrence," a statement many interpreted as a threat to conduct another nuclear test.
Pyongyang has twice before conducted nuclear tests following U.N. sanctions imposed after long-range rocket launches. Recent satellite photos suggest it may be preparing to conduct a third test.
