North Korea missile test: US allies discuss steps Defence chiefs from the US, South Korea and Japan have vowed to strengthen intelligence sharing after North Korea test-fired a ballistic missile. In a conference call, the US reaffirmed its commitment to the security of its two allies, adding its F-22 stealth fighters and a nuclear-powered submarine would join military exercises next month. The UN has also condemned the test. The Security Council called it a violation of UN resolutions and urged members to "redouble their efforts" to enforce sanctions on North Korea. SOURCE: BBC NEWS
