2 new commercial belts to bring jobs closer to homes

SINGAPORE: Jobs will be brought nearer to the homes to help ease the congestion in the city centre, with two new commercial belts.

The government, which outlined these developments in its Land Use Plan, will also make it easier for people to use public transport. And, it hopes to see 75 per cent of all journeys made by public transport by 2030, compared with the current 60 per cent.

The first new commercial belt is the North Coast Innovation Corridor, spanning Woodlands Regional Centre, Sembawang, the future Seletar Regional Centre and Punggol, to be ready in 10 to 15 years.

Seletar Regional Centre, for example, will be a major employment node for people living in the north and north east. There'll be more land for new business activities when the existing shipyard facilities in Sembawang are phased out.

By 2030, it'll be easier to get around using the Cross Island Line, Thomson Line and the new North-South Expressway.

Within the regional hubs, there are plans to start community bus services, which will operate during specific periods of the day.

The other commercial belt is the Southern Waterfront City - from Marina Bay along the waterfront from Keppel, through Telok Blangah to Pasir Panjang Terminal. It'll have more commercial and housing developments after 2027.

To serve the expected increase along the North-South corridor and optimise the use of roads, the government may introduce what it calls a "reversible flow" scheme along certain expressways.

This means the traffic can flow in one direction during the morning peak hours and move in the opposite direction during the evening peak period.

Teen who performed at inaugural events shot dead

STORY HIGHLIGHTS

• NEW: Chicago mayor: "We have a responsibility to see a stop to this"


• Hadiya Pendleton, 15, was shot dead in Chicago on Tuesday


• Last week she performed in events surrounding President Obama's inauguration


• "Just a matter of days after the happiest day of her life, she's gone," Sen. Dick Durbin says

Chicago (CNN) -- A teen who performed at events around President Barack Obama's inauguration was shot to death in Chicago this week, and now her story has become part of the debate in Washington over gun violence nationwide.

The shooting death of 15-year-old Hadiya Pendleton came up in a U.S. Senate hearing and a White House press briefing Wednesday.

"She was an honor student and a majorette," said Sen. Dick Durbin, D-Illinois. Performing at inaugural events last week "was the highlight of her young, 15-year-old life," he said.

Speaking at Wednesday's Senate Judiciary Committee hearing on gun violence, Durbin mentioned Pendleton's death as he argued that more must be done to stop gun crimes.

Giffords: 'Too many children dying'

"Yesterday, in a rainstorm after school, she raced to a shelter. A gunman came in and shot her dead," he said. "Just a matter of days after the happiest day of her life, she's gone."

The park shelter where she was shot is just a mile from Obama's home in Chicago.

White House spokesman Jay Carney described her death as a "terrible tragedy."

"The president has more than once, when he talks about gun violence in America, referred not just to the horror of Newtown or Aurora or Virginia Tech or Oak Creek but to shootings on the corner in Chicago or other parts of the country," Carney told reporters. "And this is just another example of the problem we need to deal with."

2013 has gotten off to a deadly start in Chicago -- Pendleton was the year's 42nd murder victim. No arrests have been made in the case, police said Wednesday.

In 2012, 506 people were slain in the city.

Chicago Mayor Rahm Emanuel described Pendleton Wednesday as "what's best in our city, a child going to school who takes a final exam, who had just been to the inaugural."

"We have a responsibility to see a stop to this," he said. "And all of us are responsible."

Pendleton was shot just blocks away from her high school on the south side of Chicago, CNN affiliate WGN reported.

LaPierre, the NRA's heavyweight

Police told CNN affiliates that the teenager had no gang affiliation and likely was not the intended target.

"There has to be an end to it. It's just too much. The children cannot go to school. They're in fear," Bonita O'Bannion, who lives in the area where the shooting occurred, told CNN affiliate WBBM.

Carney said the president and first lady's thoughts and prayers are with Pendleton's family.

"And as the president said, we will never be able to eradicate every act of evil in this country," Carney said, "but if we can save even one child's life, we have an obligation to try when it comes to the scourge of gun violence."

Obama: "No doubt" Congress will pass immigration, gun bills

Obama: "No doubt" gun, immigration bills will pass in coming months

There's more bipartisan support in Congress for comprehensive immigration reform than gun control legislation, President Obama said tonight during an interview with Univision, but qualified that even under his proposal, illegal immigrants shouldn't be harboring expectations that they'll be granted citizenship "manana."

"Even under our proposal, this is not a situation where overnight, suddenly people all find themselves as citizens," Mr. Obama told the Spanish-language television network. "They're going to have to go to the back of the line. We're going to have to clear out the existing line, backlogs we have in terms of illegal immigrants, because they did it the right way. We shouldn't punish them for breaking the law.

"...What we don't want to do is to create some vague prospect in the future that somehow comprehensive immigration reform that includes a pathway to citizenship will happen manana," he continued, chuckling softly at the somewhat awkward injection of the Spanish word for "tomorrow." "But we have to put that in place at the outset, and make sure people are clear that this pathway is real and not just a fantasy for the future."

Asked whether he was in a standoff with Sen. Marco Rubio, R-Fla., the son of Cuban immigrants who has said he will not support a bill that does not put border control ahead of a path to citizenship, Mr. Obama said no, but pointed out that the number of people crossing the border illegally has dropped "about 80 percent since 2000."

On Tuesday, the president delivered a speech in Las Vegas outlining his immigration plan and applauding a bipartisan group of eight senators that has offered up proposals as well. In an interview today with another Spanish language network, Telemundo, he specified that he's hoping immigration reform that includes a pathway to citizenship can be passed in the next six months, but "certainly this year."

Meanwhile, despite facing more resistance from the right on tightening gun laws, he said he has "no doubt" that Congress will be able to put through legislation on gun control, as well as immigration.

Obama: Legalization for illegal immigrants won't happen "ma?ana"

"On the gun issue, you're starting to see gun owners, people who traditionally have opposed gun control, saying, 'You know what, when 20 of our children are shot by somebody who is disturbed, and when it is that easy to get these high-clip magazines that can fire off hundreds of shots in a few minutes, then it's time for us to do better job on background checks, to get control of these magazine clips, to really crack down on gun trafficking," Mr. Obama said in the Univision interview.

The Senate Judiciary Committee today held the first congressional hearing on gun violence since last month's massacre at a Newtown, Conn., elementary school, that left 20 children and six adults dead. Star witnesses included former Rep. Gabrielle Giffords, D-Ariz., who survived a shot to the head two years ago during an assassination attempt that left six people dead, and her husband on one side, and NRA CEO Wayne LaPierre on the other.

Both gun control and immigration "will end up generating some opposition," the president said. "There will be passions on both sides. But I'm generally encouraged that the Senate seems to be having a serious conversation about these issues."

Former Police Captain Cleared of Ex-Wife's Murder

A former Ohio police captain has been cleared in the murder of his ex-wife and released from prison, where he had been for 15 years -- but prosecutors say they plan to appeal the ruling.

"I'm just a jumble of emotions and I just can't wait to hug all of my family," Douglas Prade told reporters outside the prison when he was released Tuesday afternoon, according to ABC News' Cleveland affiliate WEWS-TV.

He thanked "all of the people that supported me and communicated with me and told me to keep my spirits up."

Prade's ex-wife, Dr. Margo Prade, 41, was found shot to death in her minivan outside of her medical practice in November 1997.

Douglas Prade was an Akron, Ohio, police captain at the time.

At trial, he was convicted on murder and wiretapping charges and sentenced to life in prison.

Prade, now 66, maintained his innocence and, eventually, the Ohio Innocence Project took up his cause and petitioned for his release or a new trial based on new DNA testing.

One of the key factors in Prade's conviction was a bite mark found on Margo Prade's body. The prosecution brought in an expert that testified the bite mark came from Douglas Prade.

The Ohio Innocence Project commissioned a new DNA test that was not available at the time of the trial. The test found that the DNA around the bite was not Douglas Prade's.

Summit County Court of Common Pleas Judge Judy Hunter ruled that Prade should be set free because the new DNA results were "clear and convincing" in Prade's favor, according to the Associated Press.

Prosecutor Sherri Walsh is strongly disputing the new DNA evidence.

"This is a gross misapplication of the law, and we will be appealing Prade's exoneration. The defendant had to present new evidence so convincing that no juror would have found him guilty, and he failed to do so," Walsh said in a statement. "The DNA evidence presented by the Ohio Innocence Project on behalf of Prade is contaminated and unreliable. It does not prove innocence."

Walsh said that all evidence points to Prade as the person who killed Margo Prade.

"He was a serial stalker," Walsh said. "He tapped her phones and recorded more than 400 of her personal calls. He had verbally abused and threatened her. And we know Margo was afraid of him."

Other evidence includes Prade's handwritten tally of the bills he owed subtracted from the life insurance money he'd get if his wife died, Walsh said. Two witnesses placed him at the murder scene.

"We have not seen any credible evidence that suggests innocence, and we are taking all available actions to keep a dangerous killer off the streets," Walsh said.

Margo Prade's family is also upset by the decision.

"I feel like my life is in danger and my family's life is in danger now," Margo Prade's nephew Tony Fowler told the AP. "[Dr. Prade and her mother] are probably turning over in their graves but God will have the final say."

Alison McCarty, the former prosecutor on the case, told WEWS she respected the court's decision, but emphasized that the case is not yet closed.

"[Margo Prade] was such a superstar and it was just such a tremendous loss, and her death still needs justice," McCarty said.

The state has 30 days to file a motion in the court of appeals requesting permission to appeal the decision for a new trial.

Million mourners set to honour Cambodia's ex-king

PHNOM PENH: More than one million mourners are expected to line the streets of the Cambodian capital on Friday for a lavish funeral procession for their revered former King Norodom Sihanouk, officials say.

The late monarch's body will be transported atop a golden float shaped like a mythological bird from the royal palace -- where he has been lying in state for three months -- to a funeral pyre in a city park.

"This is our last homage to say goodbye to the great hero king," Prime Minister Hun Sen said on national radio this week.

Sihanouk died of a heart attack aged 89 in Beijing on October 15 last year.

He abdicated in 2004 after steering Cambodia through six decades marked by independence from France, civil war, the murderous Khmer Rouge regime and finally peace.

His body will be kept at the cremation site for religious ceremonies until Monday when his wife and son King Norodom Sihamoni are expected to light the pyre.

Foreign dignitaries -- including French Prime Minister Jean-Marc Ayrault, Japan's Prince Akishino and a host of Asian leaders or high-ranking officials -- are due to attend the cremation.

Flags will fly at half-mast. Radio and TV stations as well as entertainment venues have been instructed to refrain from showing "joyful spectacles", performances and concerts.

Cambodians have been urged to wear black ribbons pinned to their shirts.

"This is the first time in Cambodian history that the country holds such a large funeral for a king," said Sihanouk's long-time personal assistant Prince Sisowath Thomico.

"The nation does this to show him the same respect he gave to the country," he told AFP.

After the cremation, Sihanouk's remains will be put in a golden-colour urn that will be placed in a stupa inside the royal palace, he said, in line with the late monarch's wishes.

Large portraits of Sihanouk have been erected along Phnom Penh's streets and outside the royal palace where people have regularly gathered for religious ceremonies since his death.

"When the King-Father is cremated, it will be a big loss for Cambodia. We will lose our spirit," said Khut Simon, who joined about 100 people for one such ceremony.

"He was a good king who was incomparable," said the 61-year-old, clutching three pictures of the late monarch to her chest.

Sihanouk was just 18 when placed on the throne in 1941 by French colonial authorities, but quickly defied his patron's expectations of a pliant king.

Many elderly Cambodians fondly recall the 1950s and 1960s as a golden era, when Sihanouk led the country to independence from France and a rare period of political stability.

Hundreds of thousands filled the capital's boulevards when his body returned home from China in October.

A self-confessed "naughty boy" who married six times and fathered 14 children, the former king was also a prolific amateur filmmaker and shrewd political survivor who repeatedly backed different regimes.

He was not immune to controversy, notably aligning himself with the communist Khmer Rouge after being ousted by US-backed general Lon Nol in 1970.

After seizing power, the Khmer Rouge put Sihanouk under house arrest in the royal palace. Their 1975-79 reign of terror killed up to two million people, including five of Sihanouk's own children.

Before the Vietnamese invaded and toppled the Khmer Rouge, Sihanouk took exile in China.

He continued to push for peace, which eventually came in the 1990s. Sihanouk triumphantly regained the throne in 1993 but his influence diminished as strongman premier Hun Sen extended his grip on power.

In recent years, Sihanouk -- who battled illnesses including cancer, diabetes and heart problems -- spent long periods of time in China undergoing medical treatment, with his devoted sixth wife Monique always at his side.

Clinton Talks 2016, Stands by Benghazi Testimony

In her final television interview as Secretary of State, Hillary Clinton told ABC's Cynthia McFadden that she is "flattered and honored" at the intense interest in whether she might run for president in 2016.

But Clinton maintained that right now she's "not focused" on a presidential campaign; instead she said she wants to return to a "normal" life when she steps down from office on Friday.

Watch Cynthia McFadden's full interview with Secretary of State Hillary Clinton on "Nightline" tonight at 12:35 a.m. ET

Clinton's first order of business, she said, will be sleep.

"I hope I get to sleep in," she told McFadden with a laugh. "It will be the first time in many years. I have no office to go to, no schedule to keep, no work to do. That will probably last a few days then I will be up and going with my new projects," she said.

"I have been working or attending school full-time since I was 13. This is going to be new for me. I don't know how I'm going to react to it, to be honest."

Clinton has had no trouble articulating her reaction to what has arguably been the darkest chapter of her tenure as Secretary of State: the Sept. 11 attack on the U.S. consulate in Benghazi, Libya, in which four Americans, including Ambassador Chris Stevens, were killed.

Final Farewell: Hillary Clinton Steps Down as Secretary of State Watch Video

Secretary Clinton had a heated exchange with Republican Senator Ron Johnson during her five hours of testimony before Congress about the attack last week. Johnson accused the administration of misleading the American people about the cause of the attack, when UN Ambassador Susan Rice, on Sunday political talk shows, blamed it on protesters.

Clinton snapped back at Johnson, "Four Americans are dead. What difference does it make?" For that, she has been sharply criticized by some conservatives.

Clinton said she "absolutely" stands by her response to Johnson, maintaining that the administration has been transparent with the information it knew, when it was available. Clinton said partisan politics have no place in a response to a terrorist attack against Americans.

"I believe that we should in public life, whether you're in the administration or the Congress, de-politicize crisis and work together to figure out what happened, what we can do to prevent it and then put into place both the institutional changes and the budgetary changes that are necessary, " she said.

"When someone tries to put into a partisan lens, when they focus not on the fact that we have such a terrible event happening with four dead Americans but instead what did somebody say on a Sunday morning talk show? That to me is not in keeping with the seriousness of the issue and the obligation we all have as public servants"

FULL TRANSCRIPT: Sec. of State Hillary Clinton's "Nightline" Interview

Asked about her health, Clinton said her recent illness, concussion and blood clot were all a surprise.

"When I got sick and fainted and hit my head I was so surprised, and I thought I would just get up and go to work. And thankfully I had very good medical care and doctors who said, 'No we'd better do an MRI, we'd better do this, we'd better do that,'" she said, calling herself "lucky."

"I know now how split second beset by a virus and dehydrated, what it can do to you."

Though she confirmed she is wearing special glasses to help with double vision, a lingering issue following her illness, Clinton said that she expects to be fully recovered and operating at "full speed" soon.

The Secretary told McFadden that if she does decide to run, she would have "no problem" making her health records public.

"Of course, that goes with the territory," she said.
