NKorea warns of nuclear war amid rising tensions

SEOUL, South Korea (AP) - North Korea's communist regime has warned of a nuclear war on the Korean peninsula while vowing to step up its atomic bomb-making program in defiance of new U.N. sanctions.

The North's defiance presents a growing diplomatic headache for President Barack Obama as he prepares for talks Tuesday with his South Korean counterpart on the North's missile and nuclear programs.

South Korean President Lee Myung-bak told security-related ministers during an unscheduled meeting Sunday to "resolutely and squarely" cope with the North's latest threat, his office said. Lee is to leave for the U.S. on Monday morning.

A commentary Sunday in the North's main state-run Rodong Sinmun newspaper, carried by the official Korean Central News Agency, claimed the U.S. has 1,000 nuclear weapons in South Korea. Another commentary published Saturday in the state-run Tongil Sinbo weekly claimed the U.S. has been deploying a vast amount of nuclear weapons in South Korea and Japan.

North Korea "is completely within the range of U.S. nuclear attack and the Korean peninsula is becoming an area where the chances of a nuclear war are the highest in the world," the Tongil Sinbo commentary said.

Kim Yong-kyu, a spokesman at the U.S. military command in Seoul, called the latest accusation "baseless," saying Washington has no nuclear bombs in South Korea. U.S. tactical nuclear weapons were removed from South Korea in 1991 as part of arms reductions following the Cold War.

South Korea's Unification Ministry issued a statement Sunday demanding the North stop stoking tension, abandon its nuclear weapons and return to dialogue with the South.

On Saturday, North Korea's Foreign Ministry threatened war on any country that dared to stop its ships on the high seas under the new sanctions approved by the U.N. Security Council on Friday as punishment for the North's latest nuclear test.

It is not clear if the statements are simply rhetorical. Still, they are a huge setback for international attempts to rein in North Korea's nuclear ambitions following its second nuclear test on May 25. It first tested a nuclear device in 2006.

In Saturday's statement, North Korea said it has been enriching uranium to provide fuel for its light-water reactor. It was the first public acknowledgment the North is running a uranium enrichment program in addition to its known plutonium-based program. The two radioactive materials are key ingredients in making atomic bombs.

On Sunday, Yonhap news agency reported South Korea and the U.S. have mobilized spy satellites, reconnaissance aircraft and human intelligence networks to obtain evidence that the North has been running a uranium enrichment program.

South Korea's Defense Ministry said it could not confirm the report. The National Intelligence Service - South Korea's main spy agency - was not available for comment.

North Korea said more than one-third of 8,000 spent fuel rods in its possession has been reprocessed and all the plutonium extracted would be used to make atomic bombs. The country could harvest 13-18 pounds (6-8 kilograms) of plutonium - enough to make at least one nuclear bomb - if all the rods are reprocessed.

In addition, North Korea is believed to have enough plutonium for at least half a dozen atomic bombs.

North Korea says its nuclear program is a deterrent against the U.S., which it routinely accuses of plotting to topple its regime. Washington, which has 28,500 troops in South Korea, has repeatedly said it has no such intention.

The new U.N. sanctions are aimed at depriving the North of the financing used to build its rogue nuclear program. The resolution also authorized searches of North Korean ships suspected of transporting illicit ballistic missile and nuclear materials.

U.S. Secretary of State Hillary Rodham Clinton said the new U.N. penalties provide the necessary tools to help check North Korea's continued pursuit of nuclear weapons.

The sanctions show that "North Korea's pursuit of nuclear weapons and the capacity to deliver those weapons through missiles is not going to be accepted by the neighbors as well as the greater international community," Clinton said Saturday at a news conference in Canada.

The mayor of Hiroshima -- one of the two Japanese cities obliterated by US atom bombs during World War II -- on Sunday denounced North Korea for threatening to build more nuclear weapons, a report said.

"I am furious, with them (North Korea) for defying strong protests from the international community, including Hiroshima, the city attacked in an atomic bombing," mayor Tadatoshi Akiba said in a statement, as reported by Jiji Press.

"This means a grave challenge for the international community, which can never be forgiveable," Akiba said.

Hiroshima officials were not immediately available to confirm the report.

Akiba's comments came a day after North Korea vowed to build more nuclear bombs and to start enriching uranium for a new atomic weapons programme, after the UN Security Council called for sanctions over its nuclear test.

The 15-member Council voted unanimously Friday to slap tougher sanctions on the North to cripple its nuclear and ballistic missile programmes.

The North, describing Friday's sanctions resolution as a "vile product" of a US-inspired campaign, said it would never abandon nuclear weapons and would treat any attempt to blockade it as an act of war.

The hardline communist state, in a foreign ministry statement reported by its official news agency, said all new plutonium it extracts would be weaponised.
