"Members of the Security Council will begin to work immediately on appropriate measures under Article 41 [of the UN Charter] and the Security Council resolutions," van Bohemen said.
The Security Council met on Friday after North Korea confirmed earlier in the day that it had carried out a nuclear test in the country's northeast. The blast is believed to be the fifth and largest since Pyongyang began pursuing nuclear and ballistic missile programs, drawing condemnation from the international community. Council members also denounced the test, calling it a threat to international security.
According to the Council, the tests are in clear violation of its resolutions and the United Nations' nuclear nonproliferation protocols. Council members have frequently warned North Korea that further significant measures would be taken in response to additional nuclear tests.
