North Korea says it won't warn South Korea before an attack

(CNN) -- North Korea has upped the temperature on its neighbors, warning in a new threat that it would not give any advance notice before attacking South Korea."Our retaliatory action will start without any notice from now," Pyongyang said in a statement published Tuesday by its official news agency, KCNA.North Korea said it was responding to what it called insults from the "puppet authorities" in the South, claiming that there had been a rally against North Korea in Seoul.It called the rally a "monstrous criminal act."The renewed threats came a day after North Koreans celebrated the birthday of their country's founder, Kim Il Sung, who launched the Korean War.On Monday, U.S. Secretary of State John Kerry urged the regime in Pyongyang to ditch its nuclear program and put a lid on its fiery rhetoric if it wants to hold talks."The United States has made clear many times what the conditions are for our entering talks and they haven't changed," Kerry said during an interview with CNN's Jill Dougherty in Tokyo."The conditions have to be met where the North has to move towards denuclearization, indicate a seriousness in doing so by reducing these threats, stop the testing, and indicate it's actually prepared to negotiate," he said.Kerry was speaking at the end of a three-day trip that focused on securing fresh commitments from South Korea, China and Japan to try to persuade Pyongyang to return to the negotiating table and renounce nuclear weapons.His visit followed weeks of dramatic threats by Kim Jong Un's regime, including that of a nuclear strike on the United States and South Korea.There is uncertainty about how advanced the North's nuclear weapons program is, but Kerry on Monday reiterated the U.S. government view that Pyongyang doesn't yet have the capacity to carry out a nuclear attack.Last month, North Korea scrapped the 1953 truce that effectively ended the Korean War and said it was nullifying the joint declaration on the denuclearization of the Korean Peninsula.It also recently pledged to restart a reactor at its main nuclear complex that had been shut down under an agreement reached in October 2007 during talks with the United States, South Korea and four other countries.Kerry said Monday that the United States is concerned that North Korea's dogged pursuit of its nuclear weapons program could have consequences elsewhere in the world."It is the belief of President Obama, myself and the administration that what happens here also has an impact on perceptions in places like Iran, the Middle East, and elsewhere where we're engaged in nonproliferation efforts," he said.Pyongyang insists that its nuclear weapons are a necessary deterrent because of the threat posed to it by the United States and its allies.Multilateral talks on North Korea's nuclear program have ended in failure in the past, and Kerry said the United States isn't interested in going over old ground."We're not going to go through another cycle of artificial negotiations that are geared to simply attract some kind of aid or lull in events while they continue to pursue their devices' designs," he said.A U.S. State Department official said Monday there are no plans to move toward direct talks, "because North Korea has shown no willingness to move in a positive direction."Pyongyang on Sunday rejected a different proposal for dialogue, one by South Korea last week regarding the North's suspension of activity at the manufacturing zone that the two countries jointly operate.A statement via KCNA, the state-run news agency, called the South's offer a "crafty trick" and "empty words without any content."And a KCNA commentary Monday was titled, "U.S. is to blame for escalating tension on Korean Peninsula."Kerry's trip finishes on one of the biggest dates on the North Korean calendar: "The Day of the Sun," when citizens celebrate the birthday of Kim Il Sung, remembered as the "eternal president." He died in 1994 and would have been 101 this year.Current leader Kim Jong Un paid tribute Monday to Kim Il Sung, his grandfather, as well as his late father, Kim Jong Il, by visiting the halls where both men lie in state.

On North Korea's big day, Kerry underlines conditions for talks

(CNN) -- As North Koreans celebrated the birthday on Monday of their country's late founder, U.S. Secretary of State John Kerry urged the regime in Pyongyang to ditch its nuclear program and put a lid on its fiery threats if it wants to hold talks."The United States has made clear many times what the conditions are for our entering talks and they haven't changed," Kerry said during an interview with CNN's Jill Dougherty in Tokyo."The conditions have to be met where the North has to move towards denuclearization, indicate a seriousness in doing so by reducing these threats, stop the testing, and indicate it's actually prepared to negotiate," he said.Kerry was speaking at the end of a three-day trip that focused on securing fresh commitments from South Korea, China and Japan to try to persuade Pyongyang to return to the negotiating table and renounce nuclear weapons.His visit followed weeks of dramatic threats by Kim Jong Un's regime, including that of a nuclear strike on the United States and South Korea.There is uncertainty about how advanced the North's nuclear weapons program is, but Kerry on Monday reiterated the U.S. government view that Pyongyang doesn't yet have the capacity to carry out a nuclear attack.Last month, North Korea scrapped the 1953 truce that effectively ended the Korean War and said it was nullifying the joint declaration on the denuclearization of the Korean Peninsula.It also recently pledged to restart a reactor at its main nuclear complex that had been shut down under an agreement reached in October 2007 during talks with the United States, South Korea and four other countries.Kerry said Monday that the United States is concerned that North Korea's dogged pursuit of its nuclear weapons program could have consequences elsewhere in the world."It is the belief of President Obama, myself and the administration that what happens here also has an impact on perceptions in places like Iran, the Middle East, and elsewhere where we're engaged in nonproliferation efforts," he said.Pyongyang insists that its nuclear weapons are a necessary deterrent because of the threat posed to it by the United States and its allies.Multilateral talks on North Korea's nuclear program have ended in failure in the past, and Kerry said the United States isn't interested in going over old ground."We're not going to go through another cycle of artificial negotiations that are geared to simply attract some kind of aid or lull in events while they continue to pursue their devices' designs," he said.A U.S. State Department official said Monday there are no plans to move toward direct talks, "because North Korea has shown no willingness to move in a positive direction."Pyongyang on Sunday rejected a different proposal for dialogue, one by South Korea last week regarding the North's suspension of activity at the manufacturing zone that the two countries jointly operate.A statement via KCNA, the state-run news agency, called the South's offer a "crafty trick" and "empty words without any content."And a KCNA commentary Monday was titled, "U.S. is to blame for escalating tension on Korean Peninsula."Kerry's trip finishes on one of the biggest dates on the North Korean calendar: "The Day of the Sun," when citizens celebrate the birthday of the country's founder and "eternal president," Kim Il Sung, who died in 1994.

TOKYO (CNN) -- U.S. Secretary of State John Kerry arrived in Japan on Sunday for the last stop of his Asian tour, a trip that has largely focused on the provocations coming out of North Korea.Kerry met Sunday with Japanese Foreign Minister Fumio Kishida to discuss regional tensions, climate change and cybersecurity."We cannot in any way allow North Korea to possess nuclear weapons," Kishida said.

Should the U.S. shoot a North Korean missile down?

WASHINGTON (CNN) -- North Korea's missile maneuvering has raised the question of how the United States should respond, with some in Congress calling for shooting down anything that goes up.The issue gained new urgency on Thursday with the disclosure that a Pentagon intelligence assessment suggested North Korea may have developed the ability to fire a nuclear-tipped missile at its foes.It was the clearest acknowledgment to date by the United States about potential advances in North Korea's nuclear program, and came amid heightened concerns over recent threats by Pyongyang of attacks against South Korea and even U.S. territory.At a background briefing on Friday, a Republican member of Congress called the assessment of possible nuclear missile capability old news that first came out in 2011.However, the legislator said even a remote chance that a North Korean missile could be carrying a nuclear warhead means the United States should intercept it instead of waiting to find out.Hawkish Sen.

U.S. believes North Korea could test fire missiles at any time

(CNN) -- The Obama administration calculates it's likely North Korea may test fire mobile ballistic missiles at any time, based on the most recent intelligence showing Pyongyang probably has completed launch preparations, a U.S. official said Tuesday.The administration believes a test launch could happen without North Korea issuing a standard notice to commercial aviation and maritime shipping warning them to stay away from the missile's path, according to the official, who declined to be named because of the sensitivity of the information.He cautioned most of the information comes from satellite imagery, so it's impossible to reach a definitive conclusion because the United States has no means to gather information on the ground."We hope they issue a notification, but at this point we don't expect it.

North Korea tells foreigners in South to take safety measures

(CNN) -- North Korea issued its latest dispatch of ominous rhetoric Tuesday, telling foreigners in South Korea they should take steps to secure shelter or evacuation to protect themselves in the event of a conflict on the Korean Peninsula.The unnerving message came as Japan set up missile defenses in Tokyo, and North Korean workers failed to turn up for work in the industrial complex jointly operated by North and South Korea.In the statement published by state-run media Tuesday, the North's Korea Asia-Pacific Peace Committee reiterated accusations that Washington and Seoul were seeking to provoke a war with Pyongyang."Once a war is ignited on the peninsula, it will be an all-out war," the committee said, adding that North Korea doesn't want foreigners in South Korea to "fall victim" to a conflict.It follows a warning from the North last week to diplomats in its capital city, Pyongyang, that if war were to break out, it would not be able to guarantee their safety.But staff at the British Embassy in Seoul appeared unimpressed by the North's most recent attempt to rattle nerves in the region."We are not commenting on the specifics of every piece of rhetoric from North Korea," said Colin Gray, head of media affairs at the embassy. "Our travel advice remains unchanged.

N. Korea actions called 'clear and direct threat' to U.S. security

(CNN) -- The top U.S. commander in the Pacific called repeated North Korean violations of U.N. Security Council resolutions forbidding the "building and testing" of long-range ballistic missiles and nuclear weapons "a clear and direct threat to U.S. national security and regional peace and stability.""A major conflict in Korea could have unpredictable, long term, and far reaching impacts due to the central location of the Korean peninsula in Northeast Asia and the vital importance of Northeast Asian trade to the global economy," said Adm.

North Korea says it's pulling workers out of joint industrial zone

(CNN) -- South Korea's Unification Minister Ryoo Kihl-jae's office Monday clarified his earlier statements about North Korea's nuclear test plans by saying the North had been "continuously preparing" for another nuclear test since February, and that there hadn't been any new signs, his office said Monday.There was some confusion that earlier comments may have suggested new information indicating the North's nuclear test plans -- something that could have ratcheted up tensions with North Korea.

SEOUL, South Korea (CNN) -- South Korea's government said Sunday that it believes North Korea may test a missile about April 10, citing as an indicator Pyongyang's push for workers to leave the Kaesong Industrial Complex by then.Seoul "is on military readiness posture," South Korea's Blue House spokeswoman Kim Haeng said in a briefing.

Report: North Korea loads missiles onto launchers

(CNN) -- Two medium-range missiles have been loaded onto mobile launchers in North Korea and are ready to be launched, South Korea's semi-official Yonhap news agency reported Friday, citing military sources in Seoul.A U.S. official with direct knowledge of the information told CNN on Thursday that missile and launch components had been moved to the east coast of North Korea in the "last few days."The latest Yonhap report said the two missiles have now been hidden in an unidentified facility near the east coast.In response, South Korea has sent Aegis destroyers equipped with advanced radar systems to both of its coasts, Yonhap said, citing navy sources.The apparent deployment comes amid further threatening statements by North Korea and heightened tensions in the region -- a situation that "does not need to get hotter," a U.S. State Department spokeswoman said Thursday.The move of the missile and launch equipment could mean that Pyongyang, which unleashed another round of scathing rhetoric Thursday accusing the United States of pushing the region to the "brink of war," may be planning a missile launch soon.The components, the official said, are consistent with those of a Musudan missile, which has a 2,500-mile range, meaning it could threaten South Korea, Japan and Southeast Asia.The United States has been looking for a hidden North Korean east coast launch site or mobile launchers, a concern because a missile launched from the east coast would go over Japan, the official said.South Korean officials also believe the weapons on the launchers are Musudan missiles, according to Yonhap.It is believed a missile launch would be a "test" launch rather than a targeted strike.

U.S. reducing rhetoric that feeds North Korean belligerence

WASHINGTON (CNN) -- Recent announcements of American military deployments in response to belligerent statements by North Korea may have contributed to escalating tensions between the two countries, Pentagon officials told CNN Thursday in explaining an effort to reduce U.S. rhetoric about the reclusive state."We accused the North Koreans of amping things up, now we are worried we did the same thing," one Defense Department official said.The officials spoke on the same day a U.S. official first told CNN that communications intercepts indicated North Korea may be planning to launch a mobile ballistic missile in the coming days or weeks.South Korean Defense Minister Kim Kwan-jin told a parliamentary committee in Seoul that the North has moved a medium-range missile to its East coast for an imminent test firing or military drill, according to the semi-official South Korean news agency Yonhap.U.S. intelligence officials also have seen movement of missile and launch components over the "last few days" to the same area, an American official with direct knowledge of the information told CNN.The official said the movements are consistent with that of a Musudan missile.
