The United States, Japan and South Korea have warned that an unparalleled scale of response would be warranted if North Korea conducts a seventh nuclear bomb test.
The warning came during a news conference by foreign representatives of the three countries.
Washington and its allies believe North Korea could be about to resume nuclear bomb testing for the first time since 2017.
U.S Deputy Secretary of State, Wendy Sherman, urged North Korea to refrain from further provocations.
