MOSCOW (Sputnik) – Earlier in the day, South Korean media reported an earthquake near the North Korean nuclear facility, prompting Seoul's suspicions that Pyongyang had performed another nuclear test. North Korea announced subsequently it had successfully tested a hydrogen bomb.
"If this [test of a hydrogen bomb] is true, it will seriously complicate the situation on the Korean Peninsula and in the entire world. Globally, the focus should be on developing a new concept of international security under the auspices of the UN Security Council," Frants Klintsevich told RIA Novosti.
"Finally, and we are talking about this all the time, we need to, at least temporarily, drop the differences on minor issues, focusing on the major threats. Probably, the world is currently facing a new challenge. It is necessary to adequately respond to it," Klintsevich noted.
North Korea declared itself a nuclear power in 2005 and conducted a series of underground nuclear weapon tests in 2006, 2009 and 2013. Pyongyang's nuclear program has triggered multiple protests from the international community.
