North Korea tested a new underwater nuclear weapon earlier this week capable of spawning a "radioactive tsunami", Pyongyang's state media said on Friday.

Separately, the North also conducted a cruise missile drill using missiles "tipped with a test warhead simulating a nuclear warhead" as it slammed the combined military exercises between South Korea and the US as an "actual drill" for "occupying" Pyongyang, Pyongyang's official Korean Central News Agency (KCNA) said in a report.
