Kerry says China's approach to N. Korea has failed, urges tougher measures

Nuclear War At Boiling Point According To Experts

In a related move, South Korea's presidential office said Seoul would resume loudspeaker propaganda broadcasts across the demilitarized zone at noon Friday.

"At this stage, we don't think it is appropriate to talk about the withdrawal or closure of the complex", said spokesperson Jeong Joon-hee of South Korea's unification ministry, which restricted access to Kaesong from south of the border a day earlier. The response could be even greater this time around, as the broadcasts will pointedly resume on the North Korean leader's birthday.

World powers are looking at ways to punish Pyongyang for the test of what it called a new and powerful hydrogen bomb.

But the United Kingdom has urged the country to go easy on the propaganda for fear of needlessly enraging North Korea.

Tokyo, which became a nonpermanent member of the U.N. Security Council this month, will work with Washington in putting together a new resolution condemning North Korea. If the sanctions are reimposed, North Korea will surely be incensed, and that could affect its investigation into the whereabouts of the abductees. For current sanctions and any new penalties to work, better cooperation and stronger implementation from Pyongyang's protector China is seen as key.

It may take weeks or longer to confirm or contradict the North's claim that it successfully tested a hydrogen bomb, which would mark a major and unanticipated advance for its still-limited nuclear arsenal. Nevertheless, this is the fourth nuclear test by North Korea. The US is highly unlikely to restore the tactical nuclear missiles it removed from South Korea in 1991, experts said.

Deputy defence ministers of South Korea, the United States and Japan on Friday held a video teleconference to share information on North Korea's nuclear test. North Korea responded by launching artillery shells at the loudspeakers and announcing a "quasi-state of war." .

The propaganda broadcasts will be the first since August, when North Korea threatened to attack its southern neighbor when the country blasted pop songs and criticism of the North Korean government from speakers along the border. Un might be termed as the ruthless dictator, but for North Koreans he is their saviour. In a press conference, White House press secretary Josh Earnest said an initial analysis by US intelligence agencies is "not consistent with North Korean claims of a successful hydrogen bomb test". The B-2 is capable of secretly infiltrating North Korea territory undetected, while equipped with nuclear weapons.

It is in response to Pyongyang's claim to have detonated a hydrogen bomb.
