North Korea has threatened to sink Japan and said the U.S. should be "beaten to death like a rabid dog" after the two countries spearheaded fresh UN Security Council sanctions in response to the regimes nuclear test earlier this month, a media report said.
South Korea has been accelerating efforts to ramp up its military capabilities in face of a torrent of nuclear weapons tests by North Korea, which on September 3 conducted its sixth and most powerful nuclear test to date.
The blast sparked global outrage, prompting the Security Council's resolution on Monday that backed the new sanctions against Kim Jong-Un's regime. If enforced, it would deprive North Korea of 30 percent of its annual fuel imports.
"The four islands of the archipelago should be sunken into the sea by the nuclear bomb of Juche", North Korea's state-run news said Thursday, citing a statement by a spokesman for the Korea Asia-Pacific Peace Committee that referred to the country's philosophy of self-reliance.
The caving in of land at the site, however, may not have been the result of the estimated 4.9-magnitude natural disaster that took place 8 minutes after the test, the analysts say. Japan, for example, gave an estimate of 160 kilotons, and South Korea's was as low as 50 kilotons. "If we respond to the situation with an attitude that we will counter a nuclear-armed North with a nuclear-armed South, peace can not be maintained between the two Koreas", Moon said. Satellite imagery since the test has showed evidence of numerous landslides at the test site. But the data were not sufficient to determine what type of nuclear device the North had detonated, it said.
The commission could not confirm what kind of nuclear test the North conducted, he added.
"I believe what President Trump wanted to say was that, not only South Korea and the USA, but also China and Russian Federation all together need to respond very firmly against North Korea's nuclear provocations", he said.
Shortly after the nuke test, Seoul announced it reached an agreement with Washington to remove the warhead weight limits on South Korean ballistic missiles, which under a bilateral guideline could be built for a maximum range of 800 kilometres.
"I can not solve the deterrent problem reducing it from a triad".
"This is in order to make the right conditions for dialogues and I would like to emphasize this", he said.
Pyongyang was expected to test an intercontinental ballistic rocket last Sunday as North Koreans celebrated the country's 69th anniversary of its founding, but the test did not happen.
According to Seoul's Defense Ministry, the missile would strengthen its pre-emptive strike capability against North Korea in the event of a crisis.
