(CNN) -- North Korea threatened to conduct a nuclear test and more ballistic missile tests if the U.N. Security Council doesn't withdraw its condemnation of Pyongyang's rocket launch earlier this month, the state-run Korean Central News Agency reported. A photo released by North Korea's official Korean Central News Agency showing the recent rocket launch. The U.N. Security Council "should promptly make an apology for having infringed the sovereignty of [North Korea] and withdraw all its unreasonable and discriminative 'resolutions' and decisions adopted against [North Korea]," a spokesman for the North's Foreign Ministry said in a statement. "The measures will include nuclear tests and test-firings of intercontinental ballistic missiles," the unidentified spokesman said.
