The UN Security Council will immediately begin working on a resolution to impose "further significant measures" against North Korea after its latest nuclear test, says Elbio Rosselli, the council's current president.
The council says that the test was in violation of previous resolutions and "a clear threat to international peace and security continues to exist."
Motohide Yoshikawa, Japanese ambassador to the UN, says the council is united in its decision to draft a new resolution, without specifying what measures it is considering.
"Our aims is to have swiftly a new resolution which has a robust content," Yoshikawa says. "We have some further ideas and we will be discussing that with the other members."
