The United Nations Security Council on Wednesday condemned a North Korean nuclear test and said it would immediately start work on new "measures" against the country.
The statement, which followed an emergency meeting, came after leaders around the globe slammed Pyongyang's claims of a hydrogen bomb test and the potential threat it poses. The council called it a violation of previous resolutions and a "clear threat to international peace and security."
North Korea earlier announced that it conducted a miniaturized hydrogen bomb test. If verified, the trial raises the politically isolated country's nuclear capabilities and potential threat to the wider world, particularly if the bomb could be attached to a missile.
"With the perfect success of our historic H-bomb, we have joined the rank of advanced nuclear states," North Korean state television said, according to AFP. It added that the test was "an act of self-defense" against the U.S.
