North Korea said Thursday that it plans to carry out a new nuclear test and further long-range rocket launches, all of which it said are a part of a new phase of confrontation with the United States.

The North's National Defense Commission said the moves would feed into an "upcoming all-out action" that would target the United States, "the sworn enemy of the Korean people."

Carried by the state-run Korean Central News Agency, the defense commission statement followed a United Nations Security Council resolution on Tuesday that condemned North Korea's recent rocket launch and expanded existing sanctions.
