SEOUL, South Korea (AP)

South Korea’s military says North Korea is believed to have conducted its sixth nuclear test.

The Joint Chiefs of Staff in Seoul says in a statement South Korea’s military has strengthened monitoring and readiness and is mulling a variety of possible responses that could be pushed together with its ally the U.S.

The apparent test came just hours after North Korea claimed that its leader has inspected the loading of a hydrogen bomb into a new intercontinental ballistic missile.
