Obama: "No doubt" more revenue still needed

One month after signing into law a "fiscal cliff" deal upping taxes on American families making more than $450,000 a year, President Obama said today there's "no doubt" additional revenue is needed to bring down the U.S. deficit, but believes lawmakers can do it "without raising taxes again."

"I don't think the issue right now is raising rates," the president said in an interview with CBS Evening News anchor Scott Pelley. "There's no doubt we need additional revenue, coupled with smart, spending reductions in order to bring down our deficit. And we can do it in a gradual way so that it doesn't have a huge impact."

Rather than raising taxes, the president proposed gutting government waste, reforming health care - "we spend a lot more on health care than any other country does, and we don't get better outcomes," he said - and closing loopholes that he suggested allow wealthy Americans to manipulate their tax rates.

"Can we close loopholes and deductions that folks who are well connected, and have a lot of accountants and lawyers, can take advantage of, so they end up paying lower rates than say, a bus driver or a cop?" Mr. Obama asked. "The average person can't take advantage of them.

"The average person doesn't have access to Cayman Island accounts," the president continued, in what may have been a punch at 2012 Republican nominee Mitt Romney's "tax haven" in the Caribbean. "The average person doesn't have access to 'carried interest income,' where they end up paying a much lower rate on billions of dollars that they've earned.

"...We just want to make sure that the whole system is fair, that it's transparent, and that we're reducing our deficit in a way that doesn't hamper growth reduce the kinds of strategies that we need," he concluded.

Earlier this week, a new GDP report showed the U.S. economy shrank 0.1 percent in the fourth quarter of 2012. Mr. Obama reasoned that a sudden drop in defense spending amid the so-called "fiscal cliff" was to blame, and called on Congress to act to avert a series of automatic spending cuts set to trigger in March.

"Washington cannot continually operate under a cloud of crisis," he said. "That freezes up consumers, it gets businesses worried. We can't afford these self-inflicted wounds. There is a way for us to solve these budget problems in a responsible way, through a balanced approach... if we do that, there's no reason why we can't have really strong growth in 2013."

10:40 p.m. ET: Baltimore time out with :12 seconds left.

10:32 p.m. ET: Now 3rd and goal for the 49ers. A stop here would be huge for the Ravens. 1:55 left in the game.

10:29 p.m. ET: Second and goal at the 5-yard line. This game is crazy. 49ers take a timeout at the 2 minute warning.

10:28 p.m. ET: And another quick first down with 2:39 left. First and goal.

10:26 p.m. ET: On 2nd and 10 Kaepernick connects with Crabtree picking up a first down.

9:18  p.m. ET: Kaepernick scrambles for a gain of five. For somebody who has used his legs so successfully this season, he seems really hesitant to try it in this game. 2nd and 5 49ers.

9:15  p.m. ET: Touchback – 49ers will start with the ball at their 20-yard line.

9:12  p.m. ET: Game resumes largely as it played out before the delay. Flacco immediately gets a first down with a 15 yard toss.

9:11  p.m. ET: Not a great start after the delay for the 49ers. A gain of 7, but short of a first down. Andy Lee comes out for the punt.

9:10  p.m. ET: That was a 34 minute delay. No statement from the NFL yet, but that must have been really frustrating for both teams.

9:10  p.m. ET: Apparently, part of the holdup was the electrical equipment on the 49ers side going out with the power. Play set to resume in the next minute or so.

9:05  p.m. ET: Obviously, how each team reacts in the first drive right after this power outage and long delay will be huge. In case you forgot, the 49ers will get the ball at the SF 40 after a Kaepernick sack. 3rd and 13 for the Niners.

9:00  p.m. ET: And there’s already a @SuperbowlLights twitter account.

8:59  p.m. ET: Law enforcement source tells ABC News the power outage is just a technical issue, nothing nefarious. Reporters at the game say they heard a boom in the stadium before the lights went out. Lights slowly coming back on, and players still on the field.

8:51  p.m. ET: Considering the score, the fact that this power outage delay may last as long as 20 minutes, and the fact that the halftime show is over, I wonder how many people are tuning out right about now.

8:51  p.m. ET: Power surge to blame, apparently.

8:48  p.m. ET: “Bring Beyonce Back” trending on Twitter now.

8:05  p.m. ET: Still, the 49ers rallied from a 17-0 deficit to make it to the Super Bowl so it’s tough to count them out just halfway through.

8:00  p.m. ET: First half ends with a Ray Lewis sack. The likely future Hall of Famer is retiring after this game. Strangely enough, his first NFL sack was of Jim Harbaugh – who is currently coaching the 49ers. Also in that game? Randy Moss, who is currently having a rough game for the 49ers.

7:59  p.m. ET: Field goal is Good. 21-6 Ravens at the half.

7:58  p.m. ET: Really looks like the big game jitters are getting to Kaepernick. Ray Lewis sack brings out Akers for a field goal attempt.

7:55  p.m. ET: Fun Fact – Kaepernick was drafted by the Chicago Cubs as a pitcher in 2009. You can see the pitcher still in him with some of these throws.

Two worms, same brains – but one eats the other

IF TWO animals have identical brain cells, how different can they really be? Extremely. Two worm species have exactly the same set of neurons, but extensive rewiring allows them to lead completely different lives.

Ralf Sommer of the Max Planck Institute for Developmental Biology in Tübingen, Germany, and colleagues compared Caenorhabditis elegans, which eats bacteria, with Pristionchus pacificus, which hunts other worms. Both have a cluster of 20 neurons to control their foregut.

Sommer found that the clusters were identical. "These species are separated by 200 to 300 million years, but have the same cells," he says. P. pacificus, however, has denser connections than C. elegans, with neural signals passing through many more cells before reaching the muscles (Cell, doi.org/kbh). This suggests that P. pacificus is performing more complex motor functions, says Detlev Arendt of the European Molecular Biology Laboratory in Heidelberg, Germany.

Arendt thinks predators were the first animals to evolve complex brains, to find and catch moving prey. He suggests their brains had flexible wiring, enabling them to swap from plant-eating to hunting.

Psy to perform at Malaysia ruling coalition party

KUALA LUMPUR: South Korea's Psy will perform his famous "Gangnam Style" dance at an event organised by Malaysia's ruling coalition, an official said Sunday as the bloc tries to attract young voters ahead of polls.

Psy will perform the hit, which made history as the most-watched video on YouTube, at a Chinese New Year party on the northern island of Penang on February 11, said Loh Hock Hun from the Malaysian Chinese Association (MCA).

The organisers hope to attract some 60,000 people including Prime Minister Najib Razak, Loh said. He could not say how much the concert, to be staged by the Barisan Nasional coalition of which the MCA is part, would cost.

Some 25 percent of Malaysia's 29 million people are ethnic Chinese and celebrate the lunar new year.

Najib, who must face tough elections by June at the latest, hopes to improve on his coalition's worst ever poll performance in 2008. Those aged below 40 make up 40 percent of the electorate.

In 2008, the coalition lost its traditional two-thirds parliament majority and control over five states including Penang, to a resurgent opposition amid voter complaints that Barisan Nasional leaders seemed too aloof and corrupt.

South Korean pop music is popular in Malaysia with a recent show, the annual Golden Disk Awards featuring performances by Super Junior and other acts, drawing thousands of fans.

Psy, who is slated to perform in Brazil's carnival celebrations next week, is also expected to take the stage in Malaysia in March for a music show at the Sepang International Circuit racetrack.

Psy made Internet history last December when "Gangnam Style" -- featuring his signature horse-riding dance -- clocked more than one billion views on YouTube.

Body of missing American found in Turkey

STORY HIGHLIGHTS

• Body of New York woman found in Istanbul


• She disappeared almost two weeks ago


• Sarai Sierra was a mother a two


• She failed to arrive at Newark, New Jersey, airport

(CNN) -- The family of an American woman who went missing in Istanbul nearly two weeks ago is in mourning after learning that Turkish police found her body Saturday.

Steven Sierra wept during a phone call with CNN, as he waited in Istanbul to go with police to identify the body of his wife, Sarai Sierra.

Turkish police found the New York woman's body near ancient stone walls in Istanbul's Sarayburnu district, the semi-official Anatolian Agency reported. Police suspected she had been killed at another location.

Police told CNN's sister network CNN Turk that the body of the 33-year-old mother of two showed signs of stab wounds.

At least nine suspects had been detained in connection with Sierra's disappearance and death, Anatolian reported.

Sierra's family and friends first sounded the alarm last week after she did not arrive on a return flight from Istanbul on January 22.

"The last we heard from my wife was Monday morning on the 21st. She had spoken with her sister and the last thing she said was, 'I'm coming home tomorrow,' and she was excited and put a little smiley face at the end of her statement," said Steven Sierra in an interview with CNN earlier this week.

Steven Sierra spoke to CNN in Istanbul on Wednesday, after he and Sarai Sierra's brother, David Jimenez, traveled to Turkey to assist in the search.

The worried husband was periodically overwhelmed with emotion throughout the interview.

"You're hoping that she's OK wherever she's at, that she's not hurting, that she's not cold, that she's being fed," Steven Sierra said, choking back tears.

"Its difficult what's going through my mind, if our hopes and prayers are not answered. It is difficult when you have two children that look up to you, and you have to do your very best to stay strong regardless of what happens."

Sarai Sierra flew alone to Istanbul on January 7 after a friend at the last minute canceled plans to accompany her.

"She did a lot of researching about the area, about where she was going to stay, the safest places to go and the time of day to travel," friend Magalena Rodriguez said.

Sierrra was an amateur photographer who had amassed more than 3,000 followers since she joined the photo sharing app Instagram last year.

Some people she met through the service encouraged her to visit the ancient Turkish city, her husband said. They offered to act as tour guides. "You're admiring pictures, but you're getting acquainted with people that you've never met before," Steven Sierra said.

Sarai's brother said he had been worried about his sister's solo trip.

"We were nervous. Were just like 'always be mindful of what you do, be aware of your surroundings. Don't get too comfortable to the point where you drop your guard down,'" David Jimenez said.

But Jimenez and Sierra's husband said Sarai was determined to complete challenges that she set for herself.

As an example, they described how she competed in a triathlon several years ago, despite being a weak swimmer, and despite the fact that she did not own a bicycle. Instead, Sarai completed the cycling leg of the competition by borrowing a mountain bike from her husband.

After arriving in Istanbul, Sierra's photo feed displayed images of Istanbul's beautiful skyline and historic landmarks.

She also squeezed in an excursion to Amsterdam in the Netherlands and to Germany, starting January 15.

"She chose to go to Amsterdam for the graffiti," her husband said. "She informed me as far as how her time was out there. And she also had a tour guide that was helping her out there as well, who I know about and who I've spoken with personally."

Sierra returned to Istanbul on January 19. Three days later, she went missing.

Sierra had rebooked her flight to arrive back early, on January 22, in part to surprise her two sons, 9 and 11.

Days before her scheduled trip home, Sierra spoke with her father, Dennis Jimenez, via Skype to remind him of her flight number and arrival time.

When Dennis Jimenez went to the Newark, New Jersey, airport to pick Sierra up, she didn't show, he said.

The airline told him she had never checked in for the flight.

"She kept in contact with us all the time," Sierra's mother, Betzaida Jimenez, said. "And then not to hear from her? It's not like her."

After the tourist went missing, Turkish police released a surveillance camera video of Sarai at a shopping mall in Istanbul, flipping through her iPad.

The scenes from January 20 are the last known images of her.

The manager of the small private hotel where Sierra was staying reported last seeing her the day the surveillance video was shot. That was a Sunday.

Her Skype account, which she avidly used, went silent a day later. A day after that was when she missed her flight home.

The time she last talked with her family, Sierra was planning on January 21 to see the Galata Bridge and visit the Asian side of Istanbul, her husband said.

The former capital of the Byzantine and East Roman empires straddles the continents of Europe and Asia.

After Sierra's family raised the alarm that she was missing, some of her belongings -- including her passport and medical cards -- were found in her room in Istanbul, though her iPhone and iPad were not there, according to her husband.

Since Sierra's disappearance, Turkish police detained a Turkish man she had been in contact with who was identified only by the first name Talan, according to CNN Turk.

Millions of foreign tourists visit Turkey every year.

While it is not unusual to hear about foreigners being targeted by pickpockets and bag snatchers, violent crime involving foreign tourists is relatively rare.

Town mourns for slain bus driver amid Ala. standoff

Updated 9:45 PM ET

MIDLAND CITY, Ala. As the police standoff with an Alabama man accused of holding a 5-year-old boy hostage continued Saturday, a nearby community prepared to bury the beloved bus driver who was shot to death trying to protect children on his bus when the episode began days earlier.

Charles Albert Poland Jr., 66, who was known around town as Chuck, was described by folks in his hometown of Newton as a humble hero. Hundreds of people attended a viewing service for Poland on Saturday evening. His funeral was set for Sunday afternoon.

"I believe that if he had to do it all over again tomorrow, he would," said Poland's sister-in-law, Lavern Skipper, earlier Saturday. "He would do it for those children."

Ala. hostage standoff: New info on kidnapper

Authorities said Jim Lee Dykes boarded a stopped school bus filled with 21 children Tuesday afternoon and demanded two boys between 6 and 8 years old. When Poland tried to block his way, the gunman shot him several times and took one 5-year-old boy — who police say remains in an underground bunker with Dykes.

Dale County Sheriff Wally Olson said in a briefing with reporters Saturday that Dykes has told them he has blankets and an electric heater in the bunker on his property. Authorities have set up a command post at a church and have been communicating with Dykes through a ventilation pipe to the underground bunker.

Olson also said Dykes has allowed police to deliver coloring books, medication and toys for the boy.

"I want to thank him for taking care of our boy," Olson said. "That's very important."

The shooting and abduction took place in Midland City, a small town near Dothan, Ala., in the state's southeastern corner.

Newton is about three miles away, a small hamlet with fewer than 2,000 residents. It sits amid cotton farms and rolling hills sprinkled with red earth; most of the residents commute to Dothan or to a nearby Army post.

William Lisenby, a school bus driver who also taught Sunday School with Poland, was flanked by other area bus drivers as he arrived at Saturday night's viewing service for his friend at a local funeral home.

Lisenby spoke in Biblical terms when referring to Poland.

"If you'll notice the similarities there, of what Chuck did was the same thing that Jesus Christ did. These children, even though they were not Chuck's, he laid down his life to defend those children. My hat's off to him for that."

"He was a bus driver just like we are," Lisenby said. "But for the grace of God that could have been us."

Others spoke of the loss of a good man, and their hope that the little boy being held captive is alive and well and will be released soon.

"The community is real concerned," said Fred McNab, mayor of Pinckard, Ala. "You can tell by the food that's been carried over there to the church. It's just devastating. We want it to come to a resolution. We want to save that little child."

Earlier Saturday, local residents remembered Poland as a friendly, giving person.

"He's probably the nicest guy you'll ever meet," said Lonnie Daniels, the 69-year-old owner of the NAPA Auto Parts store, one of three establishments in town that was open Saturday.

Daniels last saw his friend Tuesday morning, when Poland agreed to buy a car from him. The two men shook hands and closed the deal "like gentlemen," Daniels said. Poland was to return after working his bus route to pay for the car.

"He never came back," Daniels said quietly.

Daniels said Poland had been married to his wife for 43 years. Poland was from Idaho, but his wife was from Newton. The couple lived there for decades in a small mobile home, and Poland enjoyed gardening and clearing brush from his property.

"I knew that he was always there if I needed," said Daniels, adding that Poland was an excellent mechanic with an array of tools that he lent to people in town.

Neighbors and friends said Poland did various acts of kindness for people in town, from fixing someone's tractor to tilling the garden of a neighbor who had a heart attack.

"You don't owe me anything," Poland once told a recipient of his good deed. "You're my neighbor."

Skipper said Poland and his wife would often sit on their porch, drinking coffee, praying and reading the Bible.

"They loved to be together," Skipper said.

On Saturday morning, Poland's wife wasn't home. A rack of worn trucker's caps sat on hooks on the porch, and two freshly baked pies were laid atop a cooler.

The victim's son, Aaron Poland, told NBC News that he wasn't surprised by his father's act to protect the kids on the bus.

"He considered them his children," Poland said, choking back tears. "And I know that's the reason why my dad took those shots, for his children, just like he would do for me and my sister."

Gun Violence 'Depletes Precious Natural Resource'

It took the mass shooting in Newtown, Connecticut, to prompt lawmakers to call for stricter gun legislation. But the reality is that in a city like Chicago, where 515 murders took place last year and more than 100 shooting incidents have occurred since January 1, gun violence is an ongoing issue and it has been for years. Only, these shootings have become so common that they don't make national headlines.

"We lost a classroom full of children in Connecticut which sparked national outrage that needs to be translated into action, but in Chicago, we sometimes lose a dozen or more young people every weekend," Rep. Luis Gutierrez (D-Illinois), who serves the Chicago area, said in a statement. "Too many bullets and too many guns are killing the next generation and we have got to make it stop."

Gutierrez, like many others, believe that any debate about gun violence shouldn't just take into account mass shootings that make headline news. It should also consider the chronic gun violence that takes place on a daily basis across the U.S.

In Chicago's case, many of the victims are young minorities growing up in poor, gang-ridden neighborhoods on the south and west side of the city.

Just earlier this week a 15-year-old girl who performed at President Barack Obama's recent inauguration was gunned down, The Washington Post reported.

The teen, Hadiya Pendleton, was hanging out in a park with about a dozen other young people when she was shot. Two other victims were reportedly wounded. By all accounts she was in the wrong place at the wrong time. Reports indicate that the gunman was not even aiming at her.

And Pendleton is just the latest example. Chicago police officer Ron Holt lost his son, Blair, to gun violence in the spring of 2007. The 16-year-old was shot and killed while riding a bus after school.

Holt now works with young people in the community, particularly minorities at an increased risk of engaging in dangerous behavior, to encourage them to focus on their education instead of turning to violence.

"I explain to them that if they continue to ascribe to this diabolical idea of resolving conflict with firearms they're depleting the most precious natural resource in the community, and that is them," Holt said.

What's clear is that the root of the gun problem is not just the guns. There are several factors that play a role, many of which are rarely discussed. For example, for minority youth living in urban communities characterized by poverty, violence, particularly gun violence, tends to be chronic. And the groups largely impacted tend to be African American and Hispanic.

A lot of that has to do with acculturation, according to Rahsmia Zatar, executive director of Strong Youth, a gang prevention and intervention organization. There is a sense that it's difficult to move beyond one's cultural sphere.

As a result, minorities often tend to gravitate toward other young minorities in similar situations, and turn to violence to gain a sense of control, however false it really is.

"It's easy to fall victim to feeling a sense of empowerment through violence," Zatar said. "They feel they have limited opportunities and they don't have a sense of 'I can achieve,' [or] that there is something here for me that's better."

According to the 2011 American Community Survey by the U.S. Census Bureau, more than 30 percent of Chicago's African-American population and nearly 27 percent of Hispanics live below the poverty line. Perhaps more importantly, blacks and whites remain largely segregated, with African-Americans making up the vast majority of neighborhoods in the south, and whites comprising most of the north. Latinos are somewhat more mixed, often living in "buffer" communities between blacks and whites, which could exacerbate the pressure to conform to two cultures, neither of which is entirely comfortable.

These various enclaves also suffer from a distinct gang problem. Chicago Police Commissioner Garry McCarthy told Reuters the city is plagued by the breakup of larger more established gangs into new factions that are fighting over everything from turf to money.

Then there's the city's illicit gun issue, which is bigger than New York's or Los Angeles' despite strict laws to limit weapons. Gun shops are actually outlawed in Chicago, as are assault weapons and high-capacity magazines. Handguns were even banned until 2010.

Still, in a place like Chicago it's handguns doing the most damage. According to statistics from the Bureau of Alcohol, Tobacco, Firearms and Explosives, most of the guns they recovered in Illinois were pistols, followed by revolvers and rifles. Machine guns come in a distant sixth.

Why so many guns? Gun laws in neighboring communities are not as strict, and firearms make their way into the city. According to a recent article by The New York Times, officials "seized 7,400 guns [in Chicago] in crimes or unpermitted uses last year (compared with 3,285 in New York City), and have confiscated 574 guns just since Jan. 1 — 124 of them last week alone."

And while Chicago residents are required to report the loss or theft of a handgun, that same law does not apply to all of Illinois, so a stolen firearm could easily make its way into Chicago without the owner ever reporting it missing.

The dynamics created in poor minority communities like those in Chicago combined with the sheer number of guns that make their way into such a city bear out in the overall statistics.

According to the Bureau of Justice's National Crime Victimization Survey, African Americans were disproportionately represented among homicide victims and offenders between 1980 and 2008. They were six times more likely than whites to be homicide victims and seven times more likely than whites to commit homicides.

Latinos don't fare much better. According to the National Council of La Raza, the nation's largest Hispanic advocacy organization, "Today in America, every three hours a young person is killed by firearm violence. Every 14 hours, that teen or child is Latino."

Young Latinos are especially likely to be impacted by gang violence in places like Chicago. Nationally, Hispanics are also more likely than non-Hispanics to be victims of violent crimes committed by gang members.

The impact of guns on the Latino community may explain why they're inclined to favor increased gun control. According to the Pew Research Center, while 57 percent of whites think it's more important to protect the rights of Americans to own guns than to protect gun ownership, only 29 percent of Latinos feel the same way.

Holt would certainly like to see something change. Several days after his son was killed, he received a voicemail. It was then-Senator Barack Obama. The young lawmaker had called Holt to express his condolences and to promise that if there was anything he could do in the future to help curb gun violence, he was prepared to do it. The two never spoke on the phone, but Holt remembers the message.

Astrophile: A scorched world with snow black and smoky

Astrophile is our weekly column on curious cosmic objects, from the solar system to the far reaches of the multiverse

Object: Titanium oxide snow
Location: The hot-Jupiter planet HD 209458b

There is something magical about waking up to discover it has snowed during the night. But there's no powdery white blanket when it snows on exoplanet HD 209458b. Snow there is black, smoky and hot as hell – resembling a forest fire more than a winter wonderland. Put it this way: you won't be needing mittens.

HD 209458b belongs to a family called hot Jupiters, gas-giant planets that are constantly being roasted due to their closeness to their sun. By contrast, the gas giants in our immediate neighbourhood, including Jupiter, are frigid, lying at the solar system's far reaches.

HD 209458b is also noteworthy because it is tidally locked, so one side is permanently facing towards its star while the other is in perpetual night. On the face of it, these conditions wouldn't seem to invite snow: temperatures on the day side come close to 2000° C, while the night side is comparatively chilly at around 500° C.

Snow made of water is, of course, impossible on this scorched world, but the drastic temperature differential sets up atmospheric currents that swirl material from the day side to night and vice versa. That means that any substances with the right combination of properties might be gaseous on the day side and then condense into a solid on the night side, and fall as precipitation. Say hello to titanium oxide snow.

Stuck on the surface

Although oxides of titanium make up only a small component of a hot Jupiter's atmosphere, these compounds have the right properties to fall as snow. But there was a snag that could have put a stop to any blizzards. Older computer models of hot Jupiters suggested that titanium oxides condensing in the air on the night side would snow – and remain on the relatively cool surface forever. "Imagine on Earth if you had no mechanism to evaporate water, it would never rain," says Vivien Parmentier of the Côte d'Azur Observatory in Nice, France.

Now he and colleagues have created a more detailed 3D computer model that shows that the snow can become a gas again as it falls and the temperature and pressure increase. Strong updraughts can then blow the titanium oxides back to the upper atmosphere. "The gas can come back on the top layers and snow again and again," says Parmentier.

Snowfall on HD 209458b would be like none you've ever seen. Though titanium dioxide is white and shiny, for example, the snowflakes would also contain silica oxides from the atmosphere, making them black. Since the atmosphere is also dark, snowstorms on the planet would be a smoky affair, the opposite of the white-outs we get on Earth. "It would be like being in the middle of a forest fire," says Parmentier.

Although the team studied a particular hot Jupiter, their model should apply equally to other planets of this type, suggesting hot snow is a common occurrence. Parmentier says we may have already spotted snow clouds on another hot Jupiter, HD 189733b, as spectral analysis of the planet suggests the presence of microscopic particles in its atmosphere.

David Sing of the University of Exeter, UK, who helped identify such particles on HD 189733b, says the team's new model goes a long way to explaining how titanium oxides behave on hot Jupiters. "We're pretty used to water condensing on Earth; there it is titanium because the temperatures are so much hotter."

Hot, black snow – now that would be something to wake up to.

S. Korea, US in naval drill amid N. Korea tensions

SEOUL: South Korea and the United States will hold a joint naval exercise next week, a report said Saturday, a move seen as a warning to North Korea ahead of its widely-expected nuclear test.

The three-day exercise involving a US nuclear submarine and other warships will begin on Monday in the Sea of Japan (East Sea) off the South Korean port city of Pohang, Yonhap news agency reported.

"It will include anti-submarine and anti-air trainings and maritime manoeuverings," a military official was quoted as saying in the report.

The exercise comes as tensions run high on the Korean peninsula, with Pyongyang threatening to carry out its third nuclear test in response to UN sanctions imposed for a long-range rocket launch it carried out in December.

The North said the launch was a scientific mission aimed at placing a satellite in orbit, but most of the world saw it as a disguised ballistic missile test.

South Korea's Joint Chiefs of Staff Jung Seung-Jo said Friday the drill aims to test combat readiness between Seoul and Washington while guarding against possible North Korean provocations involving submarines, according to Yonhap.

A 6,900-tonne US nuclear submarine USS San Francisco and a 9,800-tonne Aegis destroyer USS Shiloh were being mobilised for the exercise.

"The presence of a US nuclear submarine here would itself serve as a message to North Korea", Jung said.

North Korea has reportedly covered the entrance to a tunnel at its nuclear test site in an apparent effort to avoid satellite monitoring of its ongoing preparations for a possibly imminent detonation.

A camouflage net was placed on the tunnel entrance at Punggye-ri in the northeastern North Korea, the site of the two previous nuclear tests in 2006 and 2009.

But a government source in Seoul said that increased activity had been spotted at the site, which has three tunnel entrances and multiple support buildings.

"At a tunnel in the southern part of the test site in Punggye-ri, we've found that work presumed to be part of preparations for a nuclear test has entered its final stage," the unnamed source told Yonhap on Saturday.

"The North may conduct the test at either the western or southern tunnels. But the activities spotted near the southern one could be aimed at distracting us from the more likely place of the western tunnel."

Parole board: Release member of 'Manson family'

By Michael Martinez and Kyung Lah, CNN

updated 10:06 PM EST, Fri February 1, 2013

Bruce Davis was sent to prison on April 21, 1972, for the 1969 first-degree murders of two men.

STORY HIGHLIGHTS

• "He earned it," defense attorney says of recommendation


• California parole board formally recommends parole for Bruce Davis, 70


• Governor must modify, affirm or reverse the recommendation in 30 days


• Davis is serving a life sentence for 1969 first-degree murders of two men

(CNN) -- California Gov. Jerry Brown is considering whether to grant parole to a convicted murderer who followed notorious killer Charles Manson, a spokeswoman for the governor said.

Brown's office received a formal recommendation from the state board parole Friday to release Bruce Davis, 70, who would be the first Manson "family" member to secure freedom solely for good behavior.

Brown has 30 days -- or until March 3 -- to either modify, affirm or reverse the parole board's recommendation, a corrections spokeswoman said.

In 2010, Davis secured his first formal recommendation for parole by the state board, but then-Gov. Arnold Schwarzenegger reversed the board's decision.

Charles Manson: The infamous inmate

HIDE CAPTION

Davis was sent to prison on April 21, 1972, for the 1969 first-degree murders of musician Gary Hinman and stuntman Donald "Shorty" Shea. Davis is serving a life sentence.

Michael Beckman, Davis' attorney, urged Brown to grant parole.

If the case were not connected to Charles Manson, Davis would have already been released by now, Beckman said. He called it "not fair."

"He earned it," Beckman said.

"I think the governor should respect the work by his parole board. That hearing took five or six hours. They took into account everything about Bruce. And they didn't grant him parole as a favor. They didn't grant him parole on a whim. They considered it very carefully," Beckman said.

In 2010, the parole board said that Davis had not been disciplined since 1980 and participated in all available education, vocation and self-help programs.

Davis is one of several imprisoned followers of Manson, 78, who is serving a life sentence for nine murders.

Manson led his "family" of followers in a deadly spree in 1969, whose victims included eight-months-pregnant actress Sharon Tate.

Last year, Manson was denied parole for the 12th time.

Manson, whose gruesome killings inspired the best-selling book "Helter Skelter," will be up for parole again 15 years from now, when he would be 92.

CNN's Michael Cary contributed to this report.
