The UN Security Council will begin working immediately on putting forward new measures in retaliation for North Korea's fourth nuclear test, Uruguay's UN Ambassador Elbio Rosselli said on Wednesday.
"The members of the Security Council ... recalled that they have previously expressed their determination to take further significant measures in the event of another DPRK [North Korea] nuclear test," Rosselli, president of the council this month, told reporters.
On Wednesday morning North Korea announced it had successfully conducted a test of a miniaturised hydrogen nuclear bomb, however many pundits remain skeptical that the kind of nuclear device which was detonated was a hydrogen bomb. The announcement on North Korean state TV followed the detection of a 5.1 magnitude earthquake near a known North Korean nuclear test site.
"In line with this commitment and the gravity of this violation, the members of the Security Council will begin to work immediately on such measures in a new Security Council resolution," Rosseli said, noting that the test was "a clear violation of Security Council resolutions.
United Nations Secretary-General Ban Ki-moon condemned the latest nuclear test conducted by North Korea, saying it was "deeply troubling" and "profoundly destabilising for regional security."
The international community, including the US, Russia, China and Japan, also condemned the test.
"This test once again violates numerous Security Council resolutions despite the united call by the international community to cease such activities," Ban told reporters. "It is also a grave contravention of the international norm against nuclear testing," Ban said.
"I demand the DPRK [North Korea] cease any further nuclear activities and meet its obligations for verifiable denuclearisation."
North Korea is under US and UN sanctions for its nuclear and missile programmes.
Between 2006 and 2013, North Korea conducted three nuclear tests that were condemned internationally. Following the 2013 nuclear test, China joined the rest of the UN Security Council in supporting a sanctions resolution.
