The day before, North Korea had responded to a joint naval maneuver by the United States and South Korea with just as many launches of short-range ballistic missiles, which the authoritarian state is prohibited by UN resolutions. These missiles also ultimately landed in the sea.
According to the South Korean military, by reacting to the missile launches ordered by Pyongyang, the allies wanted to demonstrate “the ability and determination for immediate precision strikes” once morest targets in North Korea. The general staff in Seoul accused the other side of targeted provocations and called emphatically to “refrain from any actions that aggravate military tensions on the Korean peninsula and security concerns”.
UN resolutions prohibit North Korea from testing ballistic missiles, which, depending on the design, can also carry one or more nuclear warheads. Ballistic missiles are usually surface-to-surface missiles. The USA and South Korea fear that North Korea might also carry out a new nuclear test at any time.
