In the wake of North Korea's claimed it had carried out a successful hydrogen bomb test, the United Nations Security Council (UNSC) would be holding an emergency meeting here on Wednesday.
A closed-door morning talks between the 15-member Security Council were called by the United Nations and Japan.
US mission spokeswoman Hagar Chemali said while they cannot confirm at this time that a test was carried out, they condemn any violation of UNSC Resolutions and again call on North Korea to abide by its international obligations and commitments.
The North Korean authorities on Wednesday said they have successfully tested a hydrogen bomb amid reports of a tremor near the main nuclear test site.
The State media announced the test after monitors detected a 5.1 magnitude quake close to the Punggye-ri site.
The North is thought to have conducted three previous underground nuclear tests there since 2006. A hydrogen bomb uses fusion to create a blast far more powerful than that of a more basic atomic bomb.
