WASHINGTON (Sputnik) — North Korean television reported a successful test of a ‘miniaturized hydrogen bomb' on Wednesday.
Earlier in the day an earthquake occurred in South Korea, prompting Seoul's suspicions that Pyongyang had performed a nuclear explosion.
“This highly provocative act poses a grave threat to international peace and security and blatantly violates multiple UN Security Council resolutions,” Kerry stated.Earlier on Wednesday, the international community, including key nuclear powers, condemned Pyongyang's move, having expressed concern over possible aggravation of the situation in the region.
In 2005, North Korea declared itself a nuclear power, and conducted several nuclear weapon tests in 2006, 2009 and 2013, sparking concerns in the international community.
The UN resolutions 1718 and 1814 urge Pyongyang to refrain from nuclear tests and reengage in talks on the denuclearization of the Korean peninsula.
