An “unparalleled” scale of response would be warranted if North Korea conducts a seventh test of a nuclear weapon, the United States, Japan and South Korea have warned.

The warning was issued on Wednesday amid concerns by the US and its regional allies that North Korea could be poised to resume nuclear bomb testing for the first time since 2017.
