VIENNA - The International Atomic Energy Agency, or IAEA, denounced Friday North Korea's fifth nuclear test as a "clear violation" of U.N. Security Council resolutions.
"I strongly urge the DPRK to fully implement all relevant resolutions of the UN Security Council and the IAEA," IAEA Director General Yukiya Amano said in a statement.
Amano said the nuclear test is Pyongyang's second of the year and fifth since 2006, and a breach of Resolution 2270 of the Security Council.
"This is in clear violation of numerous UN Security Council resolutions and is in complete disregard of the repeated demands of the international community. It is a deeply troubling and regrettable act," said the Japanese diplomat.
Amano also offered IAEA's collaboration in resolving the nuclear conflict with North Korea, from where its inspectors were expelled in 2009.
The Comprehensive Nuclear-Test-Ban Treaty Organization, or CTBTO, also criticized Friday the nuclear test, which was detected by seismic sensors and later confirmed by North Korea.
"This act constitutes yet another breach of the universally accepted norm against nuclear testing; a norm that has been respected by 183 countries since 1996," CTBTO Executive Secretary Lassina Zerbo said in a statement.
Zerbo said this test reiterates the need for a binding treaty to ban nuclear testing.
"I sincerely hope that this will serve as the final wake-up call to the international community to outlaw all nuclear testing by bringing the CTBT (treaty banning nuclear tests) into force," Zerbo said.
The CTBTO is an organization, independent of the U.N. and monitors the CTBT, which was signed in 1996 but is still not in force as eight countries are yet to ratify it, including North Korea, the United States, China, Egypt, Israel, Iran, India and Pakistan.
