UN Security Council calls for more sanctions against North Korea after nuclear test

UN Security Council members have called for further sanctions against North Korea after a powerful nuclear test explosion added another layer of urgency for diplomats considering what to do about the North's persistent weapons programmes.

Scheduled after North Korea said it detonated a hydrogen bomb underground on Sunday, the emergency session comes six days after the council strongly condemned Pyongyang's "outrageous" launch of a ballistic missile over Japan.
