United Nations: The UN Security Council on Wednesday "strongly" condemned the nuclear test carried out by North Korea.
The council convened an emergency closed-door meeting on the issue, reports Xinhua news agency.
The members of the security council recalled that they have previously expressed their determination to take "further significant measures" in the event of another North Korean nuclear test, according to a press statement read by this month's Security Council President Elbio Rosselli, permanent representative of Uruguay.
The statement said "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".
The surprise announcement by North Korea that it successfully carried out its first hydrogen bomb test on Wednesday jolted the international community, as such a move may dampen the denuclearisation process on the Korean Peninsula and threaten regional stability.
The H-bomb test is the fourth nuclear test by the country, which has previously conducted three nuclear tests in 2006, 2009 and 2013.
