Pope asks for support after decision to resign

VATICAN CITY (Reuters) - Pope Benedict, in his first public comments since he announced that he would become the first pontiff in centuries to resign, on Wednesday said he was fully aware of the gravity of his decision but confident that it would not hurt the Church.

"Continue to pray for me, for the Church and for the future pope," he said in unscripted remarks at the start of his weekly general audience, one of his last public appearances before he resigns on February 28.

The pope, who looked and sounded strong, was interrupted several times by thunderous applause from the some 8,000 faithful and tourists who packed the vast audience hall.

In brief, prepared remarks that mirrored those he read to stunned cardinals when he announced his decision on Monday, the pope said God would continue to guide the Church because it was much more than its earthly leader.

"I took this decision in full freedom for the good of the Church after praying for a long time and examining by conscience before God," he said.

He said he was, "well aware of the gravity of such an act but at the same time aware of not being able to carry out my (papal) ministry with the physical and spiritual force that it requires".

Benedict said he was sustained by the "certainty that the Church belongs to Christ, who will never stop guiding it and caring for it".

He said that "he felt almost physically" the affection and kindness he had received since he announced the decision.

Later on Wednesday, an Ash Wednesday Mass that was originally scheduled to have taken place in a small church in Rome, has been moved to St Peter's Basilica so more people can attend.

Unless the Vatican changes the pope's schedule, it will be his last public Mass.

Bank of England says UK economic recovery in sight

LONDON: The Bank of England forecast on Wednesday that the British economy would experience a "slow but sustained" recovery, but 12-month inflation would top 3.0 percent in the summer months.

Gross domestic product (GDP) was expected to grow by about 2.0 percent by the end of 2014 and remain positive despite some volatility amid the ongoing eurozone crisis, the central bank said in its latest quarterly report.

"The UK economy is therefore set for a recovery," said BoE governor Mervyn King, who will be replaced by Canadian central bank boss Mark Carney in July.

"That is not to say that the road ahead will be smooth. This hasn't been a normal recession and it won't be a normal recovery.

"The bank does not expect a triple-dip recession but said GDP was likely to continue at below pre-financial crisis levels for around another two years."

The BoE report will likely ease concerns over the outlook, after a 0.3-percent contraction in the fourth quarter of 2012 left Britain on the brink of its third recession since 2008.

The bank's monetary policy committee (MPC) last week froze its key interest rate at a record-low 0.50 percent and maintained its quantitative easing cash stimulus.

In addition, last year Britain launched an £80-billion ($123.7 billion, 102 billion euros) "funding for lending" initiative -- which is aimed at providing banks with cheap funding to stimulate lending to households and businesses, and thereby boost growth.

"The MPC continues to judge that the UK economy is set for a slow but sustained recovery in both demand and effective supply, aided by a further easing in credit conditions -- supported by the bank's programme of asset purchases and the funding for lending scheme -- and some improvement in the global environment," the report said.

"But the risks are weighted to the downside, not least because of the challenges facing the euro area."

The British central bank added that household budgets would be squeezed further, with 12-month inflation set to strike 3.0 percent in the coming months and hold above its official 2.0-percent target level for another two years.

Official data had shown on Tuesday that consumer prices index (CPI) annual inflation was 2.7 percent in January for the fourth month in a row, driven partly by rebounding food and drink prices.

Court issues production warrant against Om Prakash Chautala in disproportionate assets case

NEW DELHI: A Delhi court on Wednesday sought the presence of former Haryana chief minister Om Prakash Chautala in a disproportionate assets case in which he is an accused.

Special CBI judge Manu Rai Sethi issued the production warrant for Chautala for March 2 as the 78-year-old Indian National Lok Dal (INLD) chief was not brought to the court from jail, where he is lodged following his sentence of 10- year imprisonment in another corruption case.

"Let production warrant be issued in favour of superintendent on jail No.4 (where Chautala is lodged), Tihar directing production of accused OP Chautala for March 2," the court said.

The prosecution witnesses could not be examined today owing to Chautala's absence.

The CBI had on March 26, 2010 charged Chautala indicting him for allegedly possessing assets worth Rs 6.09 crore, far exceeding his legal income between 1993 and 2006.

Two such separate cases are also on against his sons Ajay and Abhay Chautala.

Chautala and Ajay Chautala were sentenced to 10-year imprisonment by a Delhi court on January 22 for illegally recruiting 3,206 junior basic trained (JBT) teachers in the state in 2000.

The CBI had registered three separate disproportionate assets cases against Chautalas on a complaint by Haryana Congress leader Shamsher Singh Surjewala.

Earlier, all the three cases were being heard in different courts and were transferred to one court on CBI's plea that all cases be transferred before a single judge as their trials at three different courts will lead to inordinate delay in concluding them.

In its chargesheet, the CBI had alleged that Chautala's wealth was 189 per cent more than his income of Rs 3.22 crore during the period.

The CBI had also said that Ajay was possessing assets exceeding his legal income by 339.27 per cent. His legal income between May 1993 and May 2006 was Rs 8.17 crore. However, he acquired assets worth Rs 27.7 crore, CBI alleged.

Abhay owned assets worth over five times his income of Rs 22.89 crore as per income tax records during the 2000-2005 period. The agency claimed to have found Rs 119.69 crore worth of assets.

Study questions kidney cancer treatment in elderly

In a stunning example of when treatment might be worse than the disease, a large review of Medicare records finds that older people with small kidney tumors were much less likely to die over the next five years if doctors monitored them instead of operating right away.

Even though nearly all of these tumors turned out to be cancer, they rarely proved fatal. And surgery roughly doubled patients' risk of developing heart problems or dying of other causes, doctors found.

After five years, 24 percent of those who had surgery had died, compared to only 13 percent of those who chose monitoring. Just 3 percent of people in each group died of kidney cancer.

The study only involved people 66 and older, but half of all kidney cancers occur in this age group. Younger people with longer life expectancies should still be offered surgery, doctors stressed.

The study also was observational — not an experiment where some people were given surgery and others were monitored, so it cannot prove which approach is best. Yet it offers a real-world look at how more than 7,000 Medicare patients with kidney tumors fared. Surgery is the standard treatment now.

"I think it should change care" and that older patients should be told "that they don't necessarily need to have the kidney tumor removed," said Dr. William Huang of New York University Langone Medical Center. "If the treatment doesn't improve cancer outcomes, then we should consider leaving them alone."

He led the study and will give results at a medical meeting in Orlando, Fla., later this week. The research was discussed Tuesday in a telephone news conference sponsored by the American Society of Clinical Oncology and two other cancer groups.

In the United States, about 65,000 new cases of kidney cancer and 13,700 deaths from the disease are expected this year. Two-thirds of cases are diagnosed at the local stage, when five-year survival is more than 90 percent.

However, most kidney tumors these days are found not because they cause symptoms, but are spotted by accident when people are having an X-ray or other imaging test for something else, like back trouble or chest pain.

Cancer experts increasingly question the need to treat certain slow-growing cancers that are not causing symptoms — prostate cancer in particular. Researchers wanted to know how life-threatening small kidney tumors were, especially in older people most likely to suffer complications from surgery.

They used federal cancer registries and Medicare records from 2000 to 2007 to find 8,317 people 66 and older with kidney tumors less than 1.5 inches wide.

Cancer was confirmed in 7,148 of them. About three-quarters of them had surgery and the rest chose to be monitored with periodic imaging tests.

After five years, 1,536 had died, including 191 of kidney cancer. For every 100 patients who chose monitoring, 11 more were alive at the five-year mark compared to the surgery group. Only 6 percent of those who chose monitoring eventually had surgery.

Furthermore, 27 percent of the surgery group but only 13 percent of the monitoring group developed a cardiovascular problem such as a heart attack, heart disease or stroke. These problems were more likely if doctors removed the entire kidney instead of just a part of it.

The results may help doctors persuade more patients to give monitoring a chance, said a cancer specialist with no role in the research, Dr. Bruce Roth of Washington University in St. Louis.

Some patients with any abnormality "can't sleep at night until something's done about it," he said. Doctors need to say, "We're not sticking our head in the sand, we're going to follow this" and can operate if it gets worse.

One of Huang's patients — 81-year-old Rhona Landorf, who lives in New York City — needed little persuasion.

"I was very happy not to have to be operated on," she said. "He said it's very slow growing and that having an operation would be worse for me than the cancer."

Landorf said her father had been a doctor, and she trusts her doctors' advice. Does she think about her tumor? "Not at all," she said.

Charred Human Remains Found in Burned Cabin

Investigators have located charred human remains in the burned-out cabin where they believe suspected cop killer and ex-LAPD officer Christopher Dorner was holed up as the structure burned to the ground, police said.

The human remains were found within the debris of the burned cabin and identification will be attempted through forensic means, the San Bernardino County Sheriff-Coroner Department said in a news release early this morning.

Dorner barricaded himself in the cabin in the San Bernardino Mountains near Big Bear Tuesday afternoon after engaging in a gunfight with police, killing one officer and injuring another, the San Bernardino County Sheriff's Department said.

Cindy Bachman, a spokeswoman for the department, which is the lead agency in the action, said Tuesday night investigators would remain at the site all night.

FULL COVERAGE: Christopher Dorner Manhunt

When Bachman was asked whether police thought Dorner was in the burning cabin, she said, "Right. We believe that the person that barricaded himself inside the cabin engaged in gunfire with our deputies and other law enforcement officers is still inside there, even though the building burned."

Bachman spoke shortly after the Los Angeles Police Department denied earlier reports that a body was found in the cabin, contradicting what law enforcement sources told ABC News and other news organizations.

Police around the cabin told ABC News they saw Dorner enter but never leave the building as it was consumed by flames, creating a billowing column of black smoke seen for miles.

A news onference is scheduled for later today in San Bernardino.

One sheriff's deputy was killed in a shootout with Dorner earlier Tuesday afternoon, believed to be his fourth victim after killing a Riverside police officer and two other people this month, including the daughter of a former police captain, and promising to kill many more in an online manifesto.

PHOTOS: Former LAPD Officer Suspected in Shootings

Cops said they heard a single gunshot go off from inside the cabin just as they began to see smoke and fire. Later they heard the sound of more gunshots, which was the sound of ammunition being ignited by the heat of the blaze, law enforcement officials said.

Police did not enter the building, but shot tear gas inside.

One of the largest dragnets in recent history, which led police to follow clues across the West and into Mexico, apparently ended just miles from where Dorner's trail went cold last week.

It all began at 12:20 p.m. PT Tuesday, when a maid working at a local resort called 911, saying she and another worker had been tied up and held hostage by Dorner in a cabin, sources said.

The maid told police she was able to escape, but Dorner had stolen one of their cars, which was identified as a purple Nissan.

The San Bernardino Sheriff's Office and state Fish and Game officers spotted the stolen vehicle and engaged in a shootout with Dorner.

Officials say Dorner crashed the stolen vehicle and fled on foot only to commandeer Rick Heltebrake's white pickup truck on a nearby road a short time later.

"[Dorner] said, 'I don't want to hurt you, just get out and start walking up the road and take your dog with you.' He was calm. I was calm. I would say I was in fear for my life, there was no panic, he told me what to do and I did it," Heltebrake said.

"He was dressed in all camouflage, had a big assault sniper-type rifle. He had a vest on like a ballistic vest," Heltebrake added.

Ten seconds later, Heltebrake said, a "volume of gunfire" could be heard.

The gunfire was from Dorner, who exchanged fire with two deputies, sources said.

The two deputies were wounded in the firefight and airlifted to a nearby hospital, where one died, police said. The second deputy was in surgery and was expected to survive, police said.

Police sealed all the roads into the area, preventing cars from entering the area and searching all of those on the way out. All schools were briefly placed on lockdown.

Believing that Dorner might have been watching reports of the standoff, authorities asked media not to broadcast images of police offficers' surrounding the cabin, but sent him a message.

"If he's watching this, the message is: Enough is enough," Los Angeles Police Department spokesman Andy Smith told reporters at a news conference Tuesday. "It's time to turn yourself in. It's time to stop the bloodshed. It's time to let this event and let this incident be over."

China joins U.S., Japan in condemning North Korea nuclear test

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

The reclusive North said the test was an act of self-defense against "U.S. hostility" and threatened further, stronger steps if necessary.

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

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.

China, which has shown signs of increasing exasperation with the recent bellicose tone of its 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".

China is a permanent member of the Security Council.

U.S. President Barack Obama labeled the test a "highly provocative act" that hurt regional stability and pressed for new sanctions.

"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 in a statement.

The Security Council will meet on Tuesday to discuss its reaction to the test, although 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. U.N. Secretary-General Ban Ki-moon said the test was a "clear and grave violation" of U.N. Security Council resolutions.

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" that posed a grave threat to world peace.

The test "was only the first response we took with maximum restraint", an unnamed spokesman for the North Korean Foreign Ministry, which acts as Pyongyang's official voice to the outside world, said in a statement carried by the official KCNA news agency.

"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."

North Korea 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.

South Korea, still technically at war with the North after the 1950-53 civil war ended in a mere truce, also denounced the test.

The magnitude was roughly twice as large as that of 2009, Lassina Zerbo, director of the international data centre division of the Vienna-based Comprehensive Nuclear-Test Ban Treaty Organization, said. The U.S. Geological Survey said that a seismic event measuring 5.1 magnitude had occurred.

"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.

Despite China's strong response, the test is likely to be a major embarrassment for Beijing, the North's sole major economic and diplomatic ally.

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

North Korea trumpeted the announcement on its state television channel to patriotic music against the backdrop of an image of its national flag.

It 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 merely at putting satellites in space.

North Korea used plutonium in previous nuclear tests and prior to Tuesday there had been speculation it would use highly enriched uranium so as to conserve its plutonium stocks as testing eats into its limited supply of the material that could be used to construct a nuclear bomb.

"VICIOUS CYCLE"

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.

South Korea's Yonhap news agency said Pyongyang had informed China and the United States of its plans to test on Monday, although this could not be confirmed.

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

Instead, the North, 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."

But options for the international community appear to be in short supply.

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 achieved 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. He 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, prepares 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 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 the North struggles to win attention on the global stage - other than through nuclear tests and attacks on South Korea, last 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," said Jeung Young-tae, senior research fellow at the Korea Institute for National Unification in Seoul.

The European Union's foreign policy chief, Catherine Ashton, urged North Korea to refrain from further provocation.

EU member Denmark called on China to step up to the plate and use its influence to rein in its ally.

"This deserves only one thing and that is a one-sided condemnation," said Foreign Minister Villy Sovndal. "North Korea is likely the most horrible country on this planet."

Thailand warns of possible threat to US consulate

BANGKOK: Thailand said on Tuesday that it had tightened security around the US consulate in the northern city of Chiang Mai in response to warnings of a possible terrorist threat.

Prime Minister Yingluck Shinawatra said she had "instructed security officials to step up security protection" at the diplomatic facility.

"The US embassy did not make any special request but we have to be vigilant and cannot be reckless," she told reporters.

A Thai senior intelligence official who did not want to be named said the government had received information late last week about a possible threat.

"We have learned that Al-Qaeda linked Salafists (ultra-orthodox Islamists) may be planning an attack on the US consulate in Chiang Mai," he told AFP.

"It's difficult to find them because there are a lot of tourists in Chiang Mai and also it's hard for them to find weapons to mount an attack," he said.

The heightened security comes as Thailand and the United States stage 11 days of annual joint military exercises known as Cobra Gold.

A spokesman for the US embassy in Bangkok, Walter Braunohler, declined to comment on the reported threat but said the consulate in Chiang Mai was open as usual.

"We continue to take every precaution necessary," he added.

Will come to Tihar only to take Afzal's body: Family

SRINAGAR: The family of Afzal Guru, who was hanged last week for his role in 2001 Parliament attack, welcomed the Centre's decision to hand over his belongings, but said they would come to Tihar only if the government agrees to hand over his body.

"They are mixing the two things, we don't understand what they mean. We can pray even from here. We want the body to be handed back, nothing less than that," Mohammad Yasin, a cousin of Afzal from Sopore told PTI after home secretary R K Singh said in Delhi that the family will be allowed to visit Afzal's grave inside Tihar jail here.

Singh also said all belongings left behind in Tihar jail by Afzal will be handed over to his family.

But Yasin said, "We welcome handing over the belongings but it should not be mixed with the issue of handing over the body. They are different.... If they are so concerned, they should hand over the body."

Yasin said they would go to Tihar only if the body is returned.

"We will go to Delhi on our own, if it comes to that. We do not want any largesse from the government. The only thing we want from them is to return Afzal's body," he said.

On Afzal's belongings, he said "they are the real treasure left now." The belongings, according to Yasin, include his writing material, religious and other books and a radio set.

"Either they tell us to come there or we can come on our own to collect the body and the belongings," said Yasin, adding the family wants to give him a "proper burial".

Yasin said the family has written a letter in this respect to Tihar jail authorities as well as deputy commissioner Baramulla.

43-year-old Afzal was hanged and buried in Tihar jail in Delhi on February 9.

Asked about Union home minister Sushilkumar Shinde's statement that government can consider allowing the family to offer 'fatiha' (prayer) on Afzal's grave, Yasin said it was of no use.

"Where will we offer faitha? We want to bury him here (in Sopore)," he said.

He termed as "cruel joke" the letter received yesterday from Tihar Jail authorities informing the family about Afzal's hanging.

"The arrival of the letter yesterday was like rubbing salt into open wounds of the family...the wounds which may never heal," Yasin said.

He alleged that the leaders of the country were playing politics over the death of Afzal.

"Afzal was hanged -- rightly or wrongly, we don't want to go into that — but politicians should stop playing politics," he said.

Pope shows lifetime jobs aren't always for life

The world seems surprised that an 85-year-old globe-trotting pope who just started tweeting wants to resign, but should it be? Maybe what should be surprising is that more leaders his age do not, considering the toll aging takes on bodies and minds amid a culture of constant communication and change.

There may be more behind the story of why Pope Benedict XVI decided to leave a job normally held for life. But the pontiff made it about age. He said the job called for "both strength of mind and body" and said his was deteriorating. He spoke of "today's world, subject to so many rapid changes," implying a difficulty keeping up despite his recent debut on Twitter.

"This seemed to me a very brave, courageous decision," especially because older people often don't recognize their own decline, said Dr. Seth Landefeld, an expert on aging and chairman of medicine at the University of Alabama at Birmingham.

Age has driven many leaders from jobs that used to be for life — Supreme Court justices, monarchs and other heads of state. As lifetimes expand, the woes of old age are catching up with more in seats of power. Some are choosing to step down rather than suffer long declines and disabilities as the pope's last predecessor did.

Since 1955, only one U.S. Supreme Court justice — Chief Justice William Rehnquist — has died in office. Twenty-one others chose to retire, the most recent being John Paul Stevens, who stepped down in 2010 at age 90.

When Thurgood Marshall stepped down in 1991 at the age of 82, citing health reasons, the Supreme Court justice's answer was blunt: "What's wrong with me? I'm old. I'm getting old and falling apart."

One in 5 U.S. senators is 70 or older, and some have retired rather than seek new terms, such as Hawaii's Daniel Akaka, who left office in January at age 88.

The Netherlands' Queen Beatrix, who just turned 75, recently said she will pass the crown to a son and put the country "in the hands of a new generation."

In Germany, where the pope was born, Chancellor Angela Merkel, who is 58, said the pope's decision that he was no longer fit for the job "earns my very highest respect."

"In our time of ever-lengthening life, many people will be able to understand how the pope as well has to deal with the burdens of aging," she told reporters in Berlin.

Experts on aging agreed.

"People's mental capacities in their 80s and 90s aren't what they were in their 40s and 50s. Their short-term memory is often not as good, their ability to think quickly on their feet, to execute decisions is often not as good," Landefeld said. Change is tougher to handle with age, and leaders like popes and presidents face "extraordinary demands that would tax anybody's physical and mental stamina."

Dr. Barbara Messinger-Rapport, geriatrics chief at the Cleveland Clinic, noted that half of people 85 and older in developed countries have some dementia, usually Alzheimer's. Even without such a disease, "it takes longer to make decisions, it takes longer to learn new things," she said.

But that's far from universal, said Dr. Thomas Perls, an expert on aging at Boston University and director of the New England Centenarians Study.

"Usually a man who is entirely healthy in his early 80s has demonstrated his survival prowess" and can live much longer, he said. People of privilege have better odds because they have access to good food and health care, and tend to lead clean lives.

"Even in the 1500s and 1600s there were popes in their 80s. It's remarkable. That would be today's centenarians," Perls said.

Arizona Sen. John McCain turned 71 while running for president in 2007. Had he won, he would have been the oldest person elected to a first term as president. Ronald Reagan was days away from turning 70 when he started his first term as president in 1981; he won re-election in 1984. Vice President Joe Biden just turned 70.

In the U.S. Senate, where seniority is rewarded and revered, South Carolina's Strom Thurmond didn't retire until age 100 in 2002. Sen. Robert Byrd of West Virginia was the longest-serving senator when he died in office at 92 in 2010.

Now the oldest U.S. senator is 89-year-old Frank Lautenberg of New Jersey. The oldest congressman is Ralph Hall of Texas who turns 90 in May.

The legendary Alan Greenspan was about to turn 80 when he retired as chairman of the Federal Reserve in 2006; he still works as a consultant.

Elsewhere around the world, Cuba's Fidel Castro — one of the world's longest serving heads of state — stepped down in 2006 at age 79 due to an intestinal illness that nearly killed him, handing power to his younger brother Raul. But the island is an example of aged leaders pushing on well into their dotage. Raul Castro now is 81 and his two top lieutenants are also octogenarians. Later this month, he is expected to be named to a new, five-year term as president.

Other leaders who are still working:

—England's Queen Elizabeth, 86.

—Abdullah bin Abd al-Aziz al-Saud, king of Saudi Arabia, 88.

—Sabah al-Ahmad al-Jaber al-Sabah, emir of Kuwait, 83.

—Ruth Bader Ginsburg, U.S. Supreme Court associate justice, 79.

Obama Calls N. Korea Nuke Test 'Highly Provocative'

President Obama called North Korea's latest nuclear test "a highly provocative act" that undermines regional stability and threatens international peace.

North Korea announced earlier today that it successfully tested a miniaturized nuclear device underground, according to state media.

Official state media said the test was conducted in a safe manner and is aimed at coping with "outrageous" U.S. hostility that "violently" undermines the North's peaceful, sovereign rights to launch satellites. Unlike previous tests, North Korea used a powerful explosive nuclear bomb that is smaller and lighter, state media reported.

Still, Obama said in a statement this morning, "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.

"The United States remains vigilant in the face of North Korean provocations and steadfast in our defense commitments to allies in the region," he added.

The U.N. Security Council will hold an emergency meeting on North Korea's nuclear test later this morning.
China's Ministry of Foreign Affairs released a statement expressing "firm opposition" to the test.

North Korea Says it Has Conducted a Nuclear Test Watch Video

"We strongly urge the DPRK (North Korea) to abide by its denuclearization commitments, and to refrain from further actions that could lead to a deterioration of the situation," the statement read. "Safeguarding Korean Peninsula and East Asian peace and stability serves the shared interests of all parties."

China, North Korea's main ally in the region, has warned North Korea it would cut back severely needed food assistance if it carried out a test. Each year China donates approximately half of the food North Korea lacks to feed its people and half of all oil the country consumes.

Suspicions were aroused when the U.S. Geological Survey said it had detected a magnitude 4.9 earthquake Tuesday in North Korea.

The Comprehensive Test Ban Treaty Organization told ABC News, "We confirm that a suspicious seismic event has taken place in North Korea."

"The event shows clear explosion-like characteristics and its location is roughly congruent with the 2006 and 2009 DPRK nuclear tests," said Tibor Toth, executive secretary of the organization.

"If confirmed as a nuclear test, this act would constitute a clear threat to international peace and security, and challenges efforts made to strengthen global nuclear disarmament and non-proliferation," Toth said in a statement on the organization's web site.

Kim Min-seok, a South Korean Defense Ministry spokesman, told reporters that North Korea informed United States and China that it intended to carry out another nuclear test, according to the AP. But U.S. officials did not respond to calls from ABC News Monday night.

The seismic force measured 6 to 7 kilotons, according to South Korea.

"Now that's an absolutely huge explosion by conventional terms. It's a smallish, but not tiny explosion by nuclear terms. It's about two-thirds the size of the bomb that the U.S. dropped on Hiroshima," James Acton, a senior associate at the Carnegie Endowment for International Peace, told ABC News.

North Korea threatened in January to carry out a "higher-level" test following the successful Dec. 12 launch of a long range rocket. At the time, North Korea's leader Kim Jong-Un said his country's weapons tests were specifically targeting the United States.
