Malaysian PM Najib signs election integrity pledge

KUALA LUMPUR : Malaysian Prime Minister Najib Razak has revved up his campaign against graft by signing Transparency International's Election Integrity pledge.

He has also called on the ruling Barisan Nasional (BN) coalition as well as the opposition to do the same.

Corruption has been listed as one of main concerns of voters in the upcoming general election that is widely expected to be held by the end of next month.

Mr Najib stressed that failure to rid the country of corruption will taint the country's image and hamper economic and democratic progress.

Flanked by all 13 BN component party leaders, PM Najib signed a personal pledge in his office in Putrajaya to uphold democracy and good governance.

He has tasked all BN nominees to do the same, once the list of candidates standing for election is out.

Amid a looming general election, Mr Najib has led the way by signing this election integrity pledge, by declaring that as a candidate, he will not give or accept any bribes, he will uphold and give priority to interests of the rakyat (people) and comply with all the rules and regulations of Malaysia.

In his own handwriting, the prime minister wrote that "I believe that as the BN leader, I have to set a strong tone. Only a candidate who is deemed to have fought a clean and fair election will lead to a trustworthy government respected by the people". It remains to be seen whether opposition candidates will follow suit.

Tengku Adnan Mansor, secretary-general of the United Malays National Organisation, said: "I do not think they will sign, because I was told they are not interested to sign."

However, Tony Pua, chief economist at the Democratic Action Party, said: "The opposition is very happy to sign the integrity pledge, but we have asked that an additional clause be added to the pledge, whereby elected representatives who are subsequently appointed to office as EXCO members of state governments, or as cabinet ministers, are required to declare assets.

"That to us makes the integrity pledge meaningful. If you do not declare assets, it is a very empty integrity pledge."

The pledge by Transparency International Malaysia was initiated to change a political culture which has often been seen as corrupt.

Paul Low, president of Transparency International Malaysia, said; "Almost all the surveys show that the issue of corruption and integrity is the most important point.

"You may say it is cosmetic but we explained to them that you are actually making a public declaration, and you are making a social contract with them, of his own conviction or commitment, that he will uphold principles of integrity and good governance."

So while the responsibility of fulfilling the pledge lies with the signatories, Transparency International noted that it is ultimately up to the Malaysian public to monitor and hold their politicians to account, for this exercise to be successful.

STORY HIGHLIGHTS

• NEW: Police found two boxes of testosterone and needles in Pistorius' house


• NEW: Police say he once discharged a gun at a restaurant


• NEW: Police also allege Pistorius threatened to assault someone at a racetrack


• Prosecutors call Oscar Pistorius a flight risk

Pretoria, South Africa (CNN) -- Prosecutors said they will file more charges against Oscar Pistorius and argued the Olympian accused of killing his girlfriend is a flight risk who should be denied bail.

On the second day of Pistorius' bail hearing Wednesday, prosecutors also said neighbors reported hearing sounds of arguing from his home that went on for an hour the morning of the shooting.

Pistorius is charged with premeditated murder in the Valentine's Day shooting death of his girlfriend Reeva Steenkamp.

Police officer Hilton Botha testified Pistorius, 26, had offshore accounts and a house in Italy, and that if he left South Africa it would be difficult to get him back.

The athlete sat with his head bowed, sometimes crying.

Police said they found bullets in a safe inside the house and plan to charge Pistorius with possession of unlicensed ammunition. Two boxes of testosterone and needles also were found inside the home.

Steenkamp was killed in Pistorius' bathroom; Pistorius said he fired shots into the toilet door, thinking an intruder was in the room.

Botha said Pistorius shot directly at the toilet, saying if he had fired at the door, he would have missed the toilet.

Botha told the court there's no way Pistorius was acting in self-defense and said he believes the athlete knew Steenkamp was in the bathroom when he shot through the door.

Police found a firearm on the bathroom mat and two cell phones in the bathroom; neither phone had been used to make a call. There was blood on one of the phones.

Botha said police believe a blood-splattered cricket bat found in the bathroom was used to break down the door to the toilet; part of the door was lying in the bathroom.

When police entered the house, Steenkamp was dressed, wearing white shorts and a black vest.

Botha described two past police encounters involving Pistorius, suggesting he is prone to violence.

The first involved an incident at a Johannesburg restaurant in which a gun was discharged. Botha said Pistorius asked someone else to take the blame for it.

Police said the second incident took place at a racetrack where Pistorius threatened to assault someone.

The charge of premeditation makes it more difficult for Pistorius' attorneys to argue he should be released pending trial. To win bail, the defense must argue that "exceptional circumstances" exist that would justify Pistorius' release.

In a statement read by his lawyer on Tuesday, Pistorius said he would not try to flee or influence any witnesses if he is allowed out on bail, and he argued his release wouldn't be a danger to public order.

Magistrate Desmond Nair upgraded the charge against Pistorius to premeditated murder on Tuesday, saying he could not rule out the possibility that the track star planned Steenkamp's death. But Nair said he will consider downgrading the charge later.

Pistorius' affidavit in alleged murder of girlfriend

A tragic mistake?

While prosecutors and defense lawyers agree Pistorius shot Steenkamp, the track star denied intentionally killing her.

"I fail to understand how I could be charged with murder, let alone premeditated murder because I had no intention to kill my girlfriend," Pistorius said in his statement.

"We were deeply in love and couldn't be happier," he said. "I loved her and I know she felt the same way."

Pistorius' girlfriend dies on Valentine's Day

HIDE CAPTION

In his statement, Pistorius said Steenkamp came to his home February 13 for a quiet dinner. They wrapped up the night with a bit of television in bed for him, some yoga for her. She had brought him a Valentine's Day present to open the next day.

After the couple had gone to bed, he said he got up in the early hours of February 14 to close the balcony door in his bedroom when he heard a sound in the bathroom.

Pistorius said he'd been a victim of violence and burglary in the past, and realized with terror that contractors who worked at the house had left ladders outside.

Fearing someone had entered the home through an open bathroom window, Pistorius grabbed his 9mm pistol from under the bed, moved in the dark on the stumps of his amputated legs and yelled at what he thought was the intruder to get out.

"I fired shots at the toilet door and shouted to Reeva to phone the police. She did not respond and I moved backwards out of the bathroom, keeping my eye on the bathroom entrance," Pistorius said in his statement.

"Everything was pitch-dark in the bedroom and I was still too scared to switch on a light."

"When I reached the bed, I realized that Reeva was not in bed. That is when it dawned on me that it could have been Reeva who was in the toilet. I returned to the bathroom calling her name," he said.

He said he threw open the balcony door and screamed for help, put on his prosthetic legs and tried to kick in the door to the separate room inside the bathroom containing the toilet. Then, he said, he picked up a cricket bat, smashing panels out of the door before finding a key and unlocking it.

"Reeva was slumped over but alive," he said.

Pistorius said he called for help and was told to take her to the hospital himself.

He carried her downstairs and tried to help her, but she died.

A premeditated murder?

Prosecutors, however, painted a different picture.

They rejected Pistorius' claim that he mistook her for a burglar, saying it would make no sense for an intruder to hide behind a locked bathroom door.

Instead, they say Pistorius armed himself, attached his prosthetic legs and walked 7 meters (23 feet) to shoot Steenkamp through a bathroom door after a heated argument.

Defense attorney Barry Roux questioned the state's argument, asking how prosecutors would know Pistorius had put on his prosthetic legs and walked to the bathroom before shooting his girlfriend.

Police were alerted to the shooting by neighbors, and residents had "heard things earlier," police spokeswoman Denise Beukes said.

Authorities said there had been "previous incidents" at the home, including "allegations of a domestic nature," but did not provide details.

Case rivets fans and friends alike

The case of the global sports hero known as the "Blade Runner" has riveted stunned fans around the world.

Social media reaction to the case appeared to come down against the sports star, but was still noticeably mixed on CNN's Facebook page.

"There's no amount of tears that will save you," said Anthonia Nneka Nwabueze. "Pistorius must face the law for brutally killing an innocent girl -- Reeva."

"My favorite athlete but what he did is grave and must be punished," Carlos Alvarez Ochoa said.

But another person who posted called for patience.

"(N)one of us were in the house when his girlfriend was murdered, let's hold off on casting stones at Oscar Pistorius," said Adrian van Liere Since. "Just like anyone else, he deserves a just trial, and in my eyes remains innocent until proven guilty."

Coming to his defense were two acquaintances.

"I've never seen him show an angry side. I've never seen him lose his temper," Vanessa Haywood, a model and longtime friend, told CNN. "He's an incredibly kind and gentle human being."

Another endorsement came from a former girlfriend.

"I would just like to say, I have dated Oscar on off for 5 YEARS," Jenna Edkins said on Twitter. "NOT ONCE has he EVER lifted a finger to me, made me fear for my life."

Robyn Curnow and Kim Norgaard reported from South Africa; Ed Payne reported and wrote from Atlanta. CNN's Nkepile Mabuse also contributed to this report.

Former Navy SEAL on Coming Out of Shadows

It used to be that Navy SEALs didn't just operate in the shadows. They trained in them too. Their whole story stayed shrouded in mystery. Their secret missions stayed secret to the rest of us.

But when they got Osama Bin Laden, snatched back an American cargo ship taken by pirates and rescued two air workers held hostage in Somalia, then suddenly, it seemed that SEALs were headline-makers.

Add to that some SEALs wrote books about SEAL adventures and even acted in a movie about the SEAL experience using live ammunition when they made "Act of Valor." They can't quite be called "the military unit that no one ever talked about" any longer.

Watch the full story on "Nightline" TONIGHT at 12:35 a.m. ET

Rorke Denver played Lt. Commander Rorke in "Act of Valor," a film that used dozens of SEALs and went on to gross $80 million at the box office. Now, with the help of a writer, Denver is doing some pretty decent storytelling in a new book, "Damn Few: Making the Modern SEAL Warrior."

He agrees that with SEALs like him telling their stories that these guys are out in the open like never before.

"We are, at this moment in our history, when the heat is on, the missions are getting press and coverage," Denver said.

Acts of Valor: Four Boyfriends Took Bullets to Save Girlfriends Watch Video

'Zero Dark Thirty' Screenwriter Responds to Film's Controversy Watch Video

When asked if it was a good thing, he said, "time will tell."

"We are in the public eye and I think that mythology is something that people are hugely, hugely interested in and they have an appetite for it," Denver said. "So for us with the movie and then also with 'Damn Few' I had an opportunity, I feel, to authentically represent and hopefully do it from an honorable point of view and accurately do so."

It's mostly his own story Denver tells in "Damn Few," how he joined the SEALs after college -- they didn't want him at first.

"I put in my first application and they said no, and I am glad it went that way. I think the community really values resiliency and toughness and focus and a 'never quit' attitude. For me, when they said no I thought, that ain't going to cut it."

Denver didn't quit. He reapplied and went on to survive the SEALs brutal Hell Week and training, joined the team and deployed all over the world, including the deadly Al Anbar province in Iraq when the war there was at its hottest. His family waited for him to return stateside.

"The families, I feel, are the ones who pay the price of our choices," Denver said. "But I didn't appreciate how much I was asking my family to bear and experience it with me. They really are every bit a part of our experience and frankly they are the ones who are back home and praying and believing that you are going to come home."

But even his family didn't quite know what Denver did at work every day.

"I never ask questions about what he does," said his wife, Tracy.

But "Act of Valor" was revealing in that way, and Denver's wife watched the film.

"For me it was incredibly eye-opening to actually see a submarine mission or running around in the jungle, jumping out of a plane, shooting his weapons," she said. "For me, it was like, oh, so this is what you are doing when you are away. I appreciated it actually."

Insert real news events into your mobile game

Paul Marks, chief technology correspondent

(Image: MultiPlay.io)

Seen it in the news? Now play it: a mobile-game programming system allows 3D depictions of news events to be introduced into the action. It's been developed by MultiPlay.io, a British start-up that says the technology could make gameplay more current and provide new ways for designers and coders to make cash - perhaps selling "news injection" rights to news agencies, TV stations or newspapers.

The firm's HTML5 games creator, also called MultiPlay.io, lets users import 3D animations during gameplay, allowing, for instance, last week's meteor explosion over Russia to be pasted in above the game action, says one of the company's founders, Ashraf Samy Hegab. Similarly, he says, if a millionaire footballer hits the news in, say, a fight with a nightclub bouncer, lookalike avatars could engage in just such a fracas as you motor by in a driving game.

The system creates games for Apple iOS, Google Android and Windows Phone devices. Changes to games need to be made in a browser on a PC or Mac, but can be made in real time without you having to download an app update.

"We're using a clever way of splitting the game logic that lets you change the game on the fly, as easy as a drag-and-drop task in a browser," says Hegab. "You don't need to know anything about servers or 3D programming using our engine." The idea also lets you extend the game's virtual playing area by expanding the game map, or add 3D vehicles you've designed yourself, such as glitzy spacecraft or cars. You could even add a model of yourself.

But news injection is MultiPlay.io's main aim - and its founders are hoping to interest news agencies when Mobile World Congress kicks off in Barcelona, Spain, later this month. They are not alone: adding news to make games more relevant is becoming popular, with some websites beginning to offer games with news-related activities built in, such as the fascinating Game The News, which "creates its own twists on news events in a playable form".

Companies paying more bills on time

SINGAPORE: Companies are paying more bills on time, according to the Commercial Credit Bureau.

The bureau said the number of prompt commercial payments rose to 51.59 per cent in the fourth quarter of last year. That is up by a moderate 2.29 percentage points from 49.3 per cent in the previous quarter.

Prompt payment means a company has paid at least 90 per cent of its total bills within agreed upon payment terms.

It was the first time in two years that 50 per cent of prompt commercial payment transactions were recorded. This comes on the heels of a slight economic uptick in the fourth quarter last year. The Ministry of Trade and Industry estimates the economy grew by 1.1 per cent year-on-year in Q4 2012.

Year-on-year payment promptness also increased 12.09 per cent per cent from 39.5 per cent last year. Payment promptness was at its peak in Q3 2012 when it made up 61.2 per cent of all commercial transactions in Singapore.

But the number of slow payments (when a company pays less than 50 per cent of its bills on time) increased slightly last quarter, up 0.79 percentage points to 40.99 per cent.

The construction industry saw the biggest drop in defaults. Slow payments fell 8.24 percentage points to 41.19 per cent quarter-on-quarter. A year-on-year comparison shows a decline of 17.11 percentage points in payment defaults.

With heavy government investments in industrial projects and a strong pipeline of nationwide rail transit and road infrastructure projects, the downward trend in slow payments is likely to continue into the next quarter.

The retail industry - traditionally the worst paymaster - also saw defaults fall on the back of strong seasonal sales in December.

The retail sector registered 54.73 per cent slow payments, a decrease of 4.98 percentage points from Q3 2012.

The wholesale sector registered the lowest proportion of slow payments at 35.7 per cent a 4.68 percentage point increase from the previous quarter.

Murder charge against Oscar Pistorius upgraded

Oscar Pistorius is pictured with Reeva Steenkamp in Johannesburg, South Africa, in January.

STORY HIGHLIGHTS

• NEW: The upgraded charge of premeditated murder makes his case for bail more difficult


• Pistorius' defense says he shot his girlfriend thinking she was a burglar


• A prosecutor asks why a burglar would lock up in a bathroom


• Friends and family mourn the death of Reeva Steenkamp at her funeral Tuesday

Pretoria, South Africa (CNN) -- In an emotionally wrenching hearing Tuesday, a judge upgraded the charge against Oscar Pistorius to premeditated murder, saying he could not rule out the possibility that the track star planned the shooting death of girlfriend.

But the judge said he will consider downgrading the charge later.

Pistorius had been charged with murder for the Valentine's Day shooting of Reeva Steenkamp, and the hearing Tuesday was to determine whether he should be allowed to post bail.

But prosecutors had said they would try to get the charge upgraded. And throughout the proceeding, they hammered away at the possibility that Steenkamp's killing was premeditated. The defense countered by contending Pistorius thought his girlfriend was an intruder.

With the new charge, Pistorius' case for bail may prove much more difficult. The defense must now try to argue that "exceptional circumstances" exist that would justify bail.

Different accounts for shooting

Both the defense and prosecution agreed Pistorius shot and killed his girlfriend in a tragic Valentine's Day confrontation inside his upscale Pretoria home.

But the two sides gave wildly different accounts of what led to the model's death.

Pistorius sobbed uncontrollably during the hearing as prosecutors described how they say he murdered his girlfriend.

Prosecutor Gerrie Nel said Steenkamp had come over to spend the night, but the couple got in a heated argument.

The state said Pistorius armed himself, attached his prosthetic legs and walked 7 meters to shoot Steenkamp through a bathroom door.

Pistorius fired four times, Nel said; Steenkamp was struck thrice inside the locked bathroom.

Steenkamp locked the door for a reason, Nel said. "We will get to that."

As Nel spoke, Pistorius buried his face in his hands.

But defense attorney Barry Roux said the shooting was not premeditated.

Pistorius shot his girlfriend thinking she was a burglar, he said.

The prosecution doubted that assertion, asking why a burglar would lock up in a bathroom.

Roux countered by questioning how the prosecution would know that Pistorius attached his prosthetic legs and walked to the bathroom.

Police have said Pistorius and Steenkamp were the only ones in the home.

Final farewells for Steenkamp

As the drama in court unfolded, friends and family mourned Steenkamp at a private funeral in her hometown of Port Elizabeth.

"There's a space missing inside all the people she knew that can't be filled again," her brother Adam Steenkamp told reporters outside.

Steenkamp was a law school graduate whose modeling career was on the rise. She landed the cover of FHM magazine and recently appeared on a reality TV show.

On Sunday, South Africans heard Steenkamp's voice one last time after her death, when the national broadcaster aired a pre-recorded episode of the show. The model talked about her exit from "Tropika Island of Treasure," on which local celebrities compete for prize money.

"I'm going to miss you all so much and I love you very, very much," she said, blowing a kiss to the camera.

Police: Neighbors "heard things earlier"

Authorities have released little about a possible motive in the shooting.

Items found in Pistorius' home suggest Steenkamp intended to stay the night. She had an overnight bag and her iPad, a South African official familiar with a case said Monday.

The 29-year-old model was alive after she was shot, and Pistorius carried her wounded body downstairs, said the official, who was not authorized to release details to the media.

Police were alerted to the shooting by neighbors, and residents had "heard things earlier," spokeswoman Denise Beukes said.

Police said there had been "previous incidents" at the home, including "allegations of a domestic nature." They did not detail what those may been.

Detectives are investigating a blood-stained cricket bat in the home, Johannesburg's City Press newspaper reported, and are trying to determine whether it was used to attack Steenkamp, if she used the bat in self-defense, or if Pistorius used it to try to break down the bathroom door.

Pistorius, 26, has rejected the murder allegation "in the strongest terms," his agent said in a statement.

Case rivets fans

The case of the global sports hero known as the "Blade Runner" has riveted stunned fans around the world.

As he walked into court in a blue shirt and gray suit, frenzied photographers snapped away, prompting a magistrate to demand they stop.

WH: Leaked immigration plan is only partial draft

(CBS News) WASHINGTON -- Over the weekend, a partial White House plan for immigration reform leaked to the press and caused an uproar.

White House officials tell CBS News that what was leaked is real -- it's a partial draft of half a bill. What we know is the administration's current thinking about what to do about the estimated 11 million illegal immigrants living in the United States right now.

The administration wants a temporary four-year visa to provide legal status -- meaning no more deportations -- that could be renewed. After eight years, they can apply for what's known as permanent legal residency, or, more commonly, a Green Card.

(At left, watch White House Chief of Staff Denis McDonough discuss the leaked immigration plan on "Face the Nation.")

There's also administration thinking on border security and an unspecified increase in border security, subject to negotiations with Congress. For workers who try to find jobs in the future and who might not have documents, the plan includes an E-Verify system to make sure undocumented workers aren't given jobs.

GOP: Leaked WH immigration plan "counterproductive"
W.H. immigration plan circulating in case Congress talks "break down," McDonough says

What's missing is a section dealing with all future legal immigration issues: high-skilled workers, seasonal farm workers and workers who work in hotels or restaurants. Without that, this plan doesn't have much of a chance.

The plan is not likely to get through Congress without the section dealing with legal immigration. That's why Republicans were so critical this weekend.

Last year, Republicans criticized the president for being missing in action and failing to draft a bill. Now that he admits he is, Republicans say he's contaminating that process; they argue that if you don't have a comprehensive bill -- one that can pass Republicans and Democrats in both the House and Senate -- this is a futile effort.

The White House says Republicans are going to be dared to vote up or down eventually, and that they better get used to that.

Russian Meteor: Close Encounter, Preventing Impacts

Feb 18, 2013 7:03pm

MOSCOW — As if Friday’s massive meteor explosion over central Russia weren’t enough, just hours later a large asteroid buzzed dangerously close to Earth.

And that evening, the California sky was lit up by a fireball, apparently entering Earth’s atmosphere.

It’s a barrage from space that has people asking: Are we ready for the big one?

Nearly 100 tons of space debris enters Earth’s atmosphere every day. Most of it burns up or falls harmlessly into the ocean, but experts still worry that eventually something big will come our way.

The prospect of Earth getting hit by a giant hunk of space rock is concerning enough that the United Nations is gathering top minds in Italy this week to discuss it.

Scientists say the idea of blowing up an asteroid — as Bruce Willis’ character did in the movie “Armageddon” — is pure Hollywood fantasy. Even if we could hit it, it’s unlikely to stop it.

Existing sky-watching programs run by NASA and others can only spot the biggest asteroids, not the small ones that sneak up on us.

But fear not, citizens of Earth. Scientists have a plan.

RELATED: Russian Meteor: Rushing to Cash in on the Blast

One group, the non-profit B612 Foundation, proposes sending a telescope, called Sentinel, into space to detect incoming objects decades before their orbits intersect ours. Then, unmanned spacecraft could fly to them and nudge them clear of Earth’s path.

The group is trying to raise $200 million to make it happen and hopes to launch the telescope by 2016.

Another project, proposed by the University of Hawaii, aims to give earthlings a heads-up when necessary, starting by 2015.

RELATED: Meteor Events: Rare, but Dangerous

It is called the Atlas program, and the plan is to deploy a string of telescopes that would search for even smaller objects in the sky, hoping to be able to give people at least a few day’s notice that could allow time for an evacuation.

Until then, better keep Bruce Willis on speed dial.

The fish with a rainbow eye

Michael Marshall, environment reporter

(Image: Randall Benton/The Sacramento Bee)

These eyes are positively spectral. They belong to a Caribbean trumpetfish, and their many colours are created by the refraction of light.

Rays of light bend as they pass in and out of the fish's eyes, and different colours of light bend different amounts. As a result, what was previously white light splinters into bands of different colours, like a rainbow. From bottom to top in the photo, the colours in the eye follow part of the usual rainbow sequence, from orange to blue.

Like all trumpetfish, Aulostomus maculatus has a long thin body rather like that of an eel. It often swims vertically, disguising itself among vertical corals. But it also camouflages itself by swimming along the lateral lines of larger fish.

The photograph, by Randall Benton, has just won third prize in the Nature category of the World Press Photo of the Year awards 2012.
