The friendless state: China condemns N. Korean nuke test

SEOUL | Tue Feb 12, 2013 5:08pm EST

SEOUL (Reuters) - North Korea conducted its third nuclear test on Tuesday in defiance of U.N. resolutions, drawing condemnation from around the world, including from its only major ally, China, which summoned the North Korean ambassador to protest.

Pyongyang said the test was an act of self-defense against "U.S. hostility" and threatened stronger steps if necessary.

The test puts pressure on U.S. President Barack Obama on the day of his State of the Union speech and also puts China in a tight spot, since it comes in defiance of Beijing's admonishments to North Korea to avoid escalating tensions.

The U.N. Security Council held an emergency meeting at which its members, including China, "strongly condemned" the test and vowed to start work on appropriate measures in response, the president of the council said.

North Korean leader Kim Jong-un, the third of his line to rule the country, has presided over two long-range rocket launches and a nuclear test during his first year in power, pursuing policies that have propelled his impoverished and malnourished country closer to becoming a nuclear weapons power.

North Korea said the test had "greater explosive force" than those it conducted in 2006 and 2009. Its KCNA news agency said it had used a "miniaturized" and lighter nuclear device, indicating it had again used plutonium, which is suitable for use as a missile warhead.

China, which has shown signs of increasing exasperation with the recent bellicose tone of its reclusive neighbor, summoned the North Korean ambassador in Beijing and protested sternly, the Foreign Ministry said.

Foreign Minister Yang Jiechi said China was "strongly dissatisfied and resolutely opposed" to the test and urged North Korea to "stop any rhetoric or acts that could worsen situations and return to the right course of dialogue and consultation as soon as possible".

Analysts said the test was a major embarrassment to China, which is a permanent member of the Security Council and North Korea's sole major economic and diplomatic ally.

Obama called the test a "highly provocative act" that hurt regional stability.

"The danger posed by North Korea's threatening activities warrants further swift and credible action by the international community. The United States will also continue to take steps necessary to defend ourselves and our allies," Obama said.

U.S. Ambassador to the United Nations Susan Rice said Washington and its allies intended to "augment the sanctions regime" already in place due to Pyongyang's previous atomic tests. North Korea is already one of the most heavily sanctioned states in the world and has few external economic links that can be targeted.

Japanese Prime Minister Shinzo Abe said the test was a "grave threat" that could not be tolerated.

Russian Foreign Minister Sergei Lavrov urged North Korea to abandon its nuclear arms program and return to talks. NATO condemned the test as an "irresponsible act."

South Korea, still technically at war with North Korea after a 1950-53 civil war ended in a mere truce, also denounced the test. Obama spoke to South Korean President Lee Myung-bak on Tuesday and told him the United States "remains steadfast in its defense commitments" to Korea, the White House said.

MAXIMUM RESTRAINT

North Korea's Foreign Ministry said the test was "only the first response we took with maximum restraint".

"If the United States continues to come out with hostility and complicates the situation, we will be forced to take stronger, second and third responses in consecutive steps," it said in a statement carried by the official KCNA news agency.

North Korea - which gave the U.S. State Department advance warning of the test - often threatens the United States and its "puppet", South Korea, with destruction in colorful terms.

North Korea told the U.N. disarmament forum in Geneva that it would never bow to resolutions on its nuclear program and that prospects were "gloomy" for the denuclearization of the divided Korean peninsula because of a "hostile" U.S. policy.

Suzanne DiMaggio, an analyst at the Asia Society in New York, said North Korea had embarrassed China with the test. "China's inability to dissuade North Korea from carrying through with this third nuclear test reveals Beijing's limited influence over Pyongyang's actions in unusually stark terms," she said.

Mark Fitzpatrick of the International Institute for Strategic Studies think tank, said: "The test is hugely insulting to China, which now can be expected to follow through with threats to impose sanctions."

The magnitude of the explosion was roughly twice that of the 2009 test, according to the Vienna-based Comprehensive Nuclear-Test Ban Treaty Organization. The U.S. Geological Survey said that a seismic event measuring 5.1 magnitude had occurred.

U.S. intelligence agencies were analyzing the event and found that North Korea probably conducted an underground nuclear explosion with a yield of "approximately several kilotons", the Office of the Director of National Intelligence said.

Nuclear experts have described Pyongyang's previous two tests as puny by international standards. The yield of the 2006 test has been estimated at less than 1 kiloton (1,000 tons of TNT equivalent) and the second at some 2-7 kilotons, compared with 20 kilotons for a Nagasaki-type bomb.

Initial indications are that the test involved the latest version of a plutonium-based prototype weapon, according to one current and one former U.S. national security official. Both previous tests involved plutonium. If it turns out the test was of a new uranium-based weapon, it would show that North Korea has made more progress on uranium enrichment than previously thought.

The United States uses WC-135 Constant Phoenix "sniffer" aircraft to collect samples to identify nuclear explosions. These would need to be deployed quickly to detect whether highly enriched uranium rather than plutonium was used because uranium decays to undetectable levels within a matter of days. Plutonium takes much longer to decay.

North Korea trumpeted news of the test on its state television channel to patriotic music against a backdrop of its national flag.

"It was confirmed that the nuclear test that was carried out at a high level in a safe and perfect manner using a miniaturized and lighter nuclear device with greater explosive force than previously did not pose any negative impact on the surrounding ecological environment," KCNA said.

North Korea linked the test to its technical prowess in launching a long-range rocket in December, a move that triggered the U.N. sanctions, backed by China, that Pyongyang said prompted it to take Tuesday's action.

The North's ultimate aim, Washington believes, is to design an intercontinental ballistic missile capable of carrying a nuclear warhead that could hit the United States. North Korea says the program is aimed at putting satellites in space.

Despite its three nuclear tests and long-range rocket tests, North Korea is not believed to be close to manufacturing a nuclear missile capable of hitting the United States.

It used plutonium in previous nuclear tests and before Tuesday there had been speculation that it would use highly enriched uranium so as to conserve its plutonium stocks, as testing eats into its limited supply of materials to construct a nuclear bomb.

"VICIOUS CYCLE"

When Kim Jong-un, who is 30, took power after his father's death in December 2011, there were hopes that he would bring reforms and end Kim Jong-il's "military first" policies.

Instead, North Korea, whose economy is smaller than it was 20 years ago and where a third of children are believed to be malnourished, appears to be trapped in a cycle of sanctions followed by further provocations.

"The more North Korea shoots missiles, launches satellites or conducts nuclear tests, the more the U.N. Security Council will impose new and more severe sanctions," said Shen Dingli, a professor at Shanghai's Fudan University. "It is an endless, vicious cycle."

Options for the international community appear to be in short supply. Diplomats at the United Nations said negotiations on new sanctions could take weeks since China is likely to resist tough new measures for fear they could lead to further retaliation by the North Korean leadership.

Beijing has also been concerned that tougher sanctions could further weaken North Korea's economy and prompt a flood of refugees into China.

Tuesday's action appeared to have been timed for the run-up to February 16 anniversary celebrations of Kim Jong-il's birthday, as well as to achieve maximum international attention.

Significantly, the test comes at a time of political transition in China, Japan and South Korea, and as Obama begins his second term. The U.S. president will likely have to tweak his State of the Union address due to be given on Tuesday.

Japanese Prime Minister Shinzo Abe is bedding down a new government and South Korea's new president, Park Geun-hye, is preparing to take office on February 25.

China too is in the midst of a once-in-a-decade leadership transition to Xi Jinping, who takes office in March. Both Abe and Xi are staunch nationalists.

The longer-term game plan from Pyongyang may be to restart international talks aimed at winning food and financial aid. China urged it to return to the stalled "six-party" talks on its nuclear program, hosted by China and including the two Koreas, the United States, Japan and Russia.

Its puny economy and small diplomatic reach mean that North Korea struggles to win attention on the global stage - other than through nuclear tests and attacks on South Korea, the last of which was made in 2010.

"Now the next step for North Korea will be to offer talks... - any form to start up discussion again to bring things to their advantage," predicted Jeung Young-tae, senior research fellow at the Korea Institute for National Unification in Seoul.

UN warns that Sudan could use foreign military support in Darfur

UNITED NATIONS, Feb 14 (Reuters) - The U.N. Security Council warned on Thursday that funding, training, spare parts, weapons systems and other materiel supplied to Sudan's government could be used for air strikes in the Darfur region in violation of a U.N. arms embargo.

The 15-member council expressed concern that "the direct or indirect supply, sale or transfer of technical assistance and support ... could be used by the Government of Sudan to support military aircraft being used in violation" of Darfur sanctions.

The council included the warning in a unanimously adopted resolution renewing the mandate of a group of experts who monitor sanctions imposed on Darfur in 2005. The arms embargo does not ban supplying military hardware, but states must have a Sudan government guarantee that the arms will not end up in Darfur.

Mainly African tribes in Darfur - a vast arid region in the west of Sudan - took up arms against the government in Khartoum in 2003, complaining of political and economic marginalization. African Union peacekeepers were deployed in 2006 and replaced in 2008 by a joint AU-U.N. force.

Sudan's U.N. Ambassador Daffa-Alla Elhag Ali Osman told the Security Council that Sudan intends to cooperate with the panel of experts, but denied carrying out air strikes in Darfur.

"This is a fallacious claim since we use our air capacities for purely peaceful purposes," he said on Thursday.

Violence has ebbed from the 2003-04 peak but fighting still occurs as several rounds of peace talks have failed. The United Nations has estimated that around 300,000 people have died during the conflict in Darfur and some 2 million people been displaced. Khartoum puts the death toll at 10,000.

Fighting flared again at the end of December in Darfur's Jebel Marra area, prized for its fertile land, and more than 30,000 people have fled the region, the United Nations said.

The International Criminal Court has issued arrest warrants for Sudan's President Omar Hassan al-Bashir and other senior officials on charges of masterminding genocide and war crimes in Darfur. They deny this and refuse to recognize the court. (Reporting by Michelle Nichols; Editing by Vicki Allen)

(AP) ? British authorities on Tuesday raided a slaughterhouse and a meat processing company suspected of selling horsemeat labeled as beef for kebabs and burgers, shutting them down temporarily and seizing all the meat found.

It was the first time since the growing scandal broke across Europe that horsemeat being marketed as beef has been traced to suppliers in Britain, officials said, raising questions about how widespread the practice is.

Millions of burgers and frozen meals have been recalled around Europe and many accusations have been made, but so far it's not clear how horsemeat got introduced into so many beef products. French authorities have already pointed to an elaborate supply chain that involved Romanian butchers and Dutch and Cypriot traders that resulted in horsemeat disguised as beef being sold in meals like lasagna and moussaka to consumers around the continent.

Britain's Food Standards Agency said it suspended production at the Peter Boddy slaughterhouse in northern England's Yorkshire and a company it allegedly supplied horse carcasses to, Farmbox Meats, in west Wales. The agency said it was investigating how "meat products, purporting to be beef for kebabs and burgers, were sold when they were in fact horse."

"It is shocking that we actually found this practice going on within the U.K.," Environment Secretary Owen Patterson said.

Horsemeat is largely taboo in Britain and Ireland, though in France it is sold in specialty butcher shops. While no health effects have been reported, the scandal has unsettled consumers and made clear that unscrupulous dealers in the complicated network of meat wholesalers are benefiting from selling much cheaper horsemeat as beef.

Peter Boddy, the owner of the slaughterhouse, said he would cooperate with police, while the BBC quoted a spokesman from Farmbox Meats as saying "there is nothing we have done here which is not totally permissible."

Food Standards Agency director Andrew Rhodes said the companies appeared to be involved in "blatant misleading of customers." He declined to speculate on how long such alleged fraud may have gone on, saying only that officials have seized documents ? including customer lists ? from the two venues and are investigating how much horsemeat was sold as beef to how many people.

Horses are slaughtered legally in abattoirs across Britain, and the meat is exported to countries where horsemeat is eaten.

Meanwhile, authorities on the continent have not established where the mislabeling of horse as beef occurred.

In Romania, food safety officials said Tuesday that the country produced 6,300 tons of horse, mule and donkey meat last year, and that it was correctly labeled when it was exported from 35 authorized plants to other European countries.

Romanian officials have said the fraud occurred somewhere else down the line.

In rural Romania, horses are sold from individual households to abattoirs, and each animal has four sets of documents before the meat is exported.

The manager of a Romanian slaughterhouse implicated in the scandal, Doly Com, defended his plant on Tuesday and tried to assuage buyers' concerns about his company's meat.

"We have always watched closely the way we work here....and we can guarantee one hundred percent that all the products Doly Com puts on the market are certified from a quality and origin point of view. One hundred percent," said Iulian Cazacut, the plant's general manager, where horsemeat accounts for just five percent of the plant's business.

No horse was being processed Tuesday in the plant in remote northeast Romania. Dressed in white overalls, their heads and mouths hygienically covered, workers pierced cow and pork carcasses with sharp knives, sawing off hunks.

The other Romanian slaughterhouse implicated in the horsemeat scandal, Carmolimp, has also denied wrongdoing.

An Irish food company has said that burgers found to be partially horsemeat were made from meat offcuts originating in Poland, but Polish officials denied the country had shipped horsemeat.

Sweden's food safety authority on Tuesday said it would test a wide range of frozen meat products sold in supermarkets to check whether they contain horsemeat and have been mislabeled.

Peter Bradenmark, head of food control management at Sweden's National Food Agency, told the AP that the agency would test about 50 to 100 samples from supermarkets nationwide.

"What's happened is alarming," he said. "Food companies are sincere and they want to do the right thing. But sometimes things go wrong unintentionally, and unfortunately, at times it's intentional."

An invisible war rages in world's oceans

MODIS Land Rapid Response Team at NASA GSF

Researchers used samples from the Sargasso Sea and coastal Oregon waters, finding four new viruses that killed the most abundant bacteria in the oceans (SAR11) in lab experiments. Here, a phytoplankton bloom in the South Atlantic Ocean.

By Wynne Parry
LiveScience

The discovery of new viruses that appear to be spread around the world's oceans hints at a war waging between such viruses and their prey: an abundant group of bacteria.

The bacteria, collectively known as SAR11, are the most abundant organisms known to inhabit seawater.

"They are everywhere, from the surface down to the bottom, from pole to pole," said study researcher Stephen Giovannoni, a professor of microbiology at Oregon State University, adding that SAR11 microbes are most abundant in the warm waters of ocean gyres, or rotating currents, where they can account for as much as 40 percent of plankton cells.

Bacteria killers
In 1990, Giovannoni's lab first identified these microbes using DNA (the genetic code deoxyribonucleic acid) found in water collected near Bermuda in the Sargasso Sea. Microbes in this group were later identified in waters around the world. [Image Gallery: Lost in the Bermuda Triangle]

Michael Rappe, SOEST / UHM

An electron micrograph of SAR11 bacteria strain HIMB4 cultured from Kaneohe Bay, Oahu, Hawaii.

More recently, using samples collected from the Sargasso Sea?as well as from coastal Oregon waters, Giovannoni's team identified the four new viruses, which, the team found, killed SAR11 cells in laboratory experiments. They dubbed the viruses "pelagiphages," because they infect bacteria in the open ocean.

The team sequenced the genomes of these pelagiphages and compared these with DNA from other viruses. They found similarities between the pelagiphages and?viruses that attack other ocean-dwelling bacteria. One of the new viruses, however, was so new that it created a new group, called a subfamily, of so-called podoviruses.

To get an idea of the geographic spread of these pelagiphages and their close relatives, the researchers compared their sequences with viral genetic material contained in samples from the Pacific Ocean and elsewhere.

Their results indicate these are the most abundant marine viruses seen so far, Giovannoni told LiveScience.

Explaining SAR11's success
The discovery offers clues to SAR11's success. While some had speculated that the abundance of SAR11 microbes resulted from the bacteria's ability to evade predators such as viruses, Giovannoni and colleagues have suggested the microbes' key talent was their ability to grow by converting organic carbon molecules ?dissolved, brothlike, in seawater ? into carbon dioxide. (SAR11 microbes are thought to play an important role in the planet's carbon cycle.)

The discovery of abundant viruses that prey upon SAR11 supports the latter theory about the bacteria's success, Giovannoni said.

"They can be killed by the viruses, but they are still successful, because they are always growing," he said.

Viruses and their hosts often engage in an evolutionary arms race. In a paper to be published online on Thursday by the journal Nature, Giovannoni and colleagues suggest the abundance of SAR11 cells may give them an advantage by making it easier for them to share helpful DNA with each other, a common bacterial strategy. This genetic exchange enables the bacteria to adapt to the viruses, which must then adapt their counterattack.

The value of old-school technique
Giovannoni noted that the team had used a combination of genomic analysis and traditional lab techniques for this research.

As the cost of generating genetic sequence data drops, researchers are turning to this technology more and more. However, old-fashioned lab work, testing viruses isolated from seawater in cultures of SAR11 cells, was a crucial part of this research, he said.

While genomic analysis ? which looks at an organism's genetic blueprint?or genome ? is a powerful tool, it has limitations, Giovannoni pointed out. One of the viruses was so new to science that its DNA sequence could not be identified by the most widely used methods of DNA analysis; only a new and particularly powerful analysis tool allowed researchers to recognize genes it contained that were distantly related to those from other viruses, he told LiveScience.

Retiring pope faces uncharted territory

VATICAN CITY (AP) ? For months, construction crews have been renovating a four-story building attached to a monastery on the northern edge of the Vatican gardens where nuns would live for a few years at a time in cloister. Only a handful of Vatican officials knew it would one day be Pope Benedict XVI's retirement home.

On Tuesday, construction materials littered the front of the house and plastic tubing snaked down from the top floor to a cargo container as the restoration deadline became more critical following Benedict's decision to quit on Feb. 28 and live his remaining days in prayer.

From a new name to this new home to the unprecedented reality of having two living popes, Benedict is facing uncharted territory as he becomes the first pontiff in six centuries to retire.
