The council quickly agreed to a statement on Sept. 9 condemning the North's fifth and most powerful underground explosion to date after an emergency closed-door meeting called by the United States, Japan, and South Korea.
The council's statement noted the "gravity of this violation" and Pyongyang's "flagrant disregard" for previous UN resolutions, and pledged to take "further significant measures" in response.
U.S. President Barack Obama called the test a "flagrant violation" of UN resolutions that demonstrated North Korea "has no interest in being a responsible member of the international community."
Possible new steps against Pyongyang include full implementation of existing sanctions, adding new names to the sanctions list or strengthening current sanctions, said Matthew Rycroft, British ambassador to the UN.
