SEOUL (Reuters) -North Korea tested its new submarine-launched cruise missiles (SLCM) on Sunday, firing an upgraded missile for the second time in a week and accelerating its navy's nuclear armament, state media reported on Monday.
Leader Kim Jong Un supervised the test of the missile, called "Pulhwasal-3-31," which is identical to the strategic cruise missiles that the North test-launched last week as part of upgrading its weapons system.
