Migrant Workers' Centre reminds employers of their roles






SINGAPORE: The Migrant Workers' Centre has reminded employers of their responsibilities to foreign workers under Singapore's manpower regulations.

These include prompt payment of salaries, providing acceptable housing and adequate care during their stay here.

The reminder came after Tuesday' incident at a Yishun construction site where some workers stopped work as a result of unpaid salaries.

The centre's chairman, Yeo Guat Kwang, also urged the Ministry of Manpower (MOM) to respond swiftly to all foreign worker claims and complaints so that they do not take matters into their own hands out of desperation.

The centre said it has always advocated for stricter enforcement against errant employers, and is encouraged by the ministry's swift response to Tuesday's Yishun incident.

The centre said it received notice of the workers' salary dispute with Sime Chong Construction at 4pm on Tuesday, and quickly sent a team to the site.

The team worked with MOM officials, the employer and workers to reach a satisfactory resolution.

The centre also provided emergency housing for four workers who were not able to have their claims resolved on Tuesday. It will follow up with the ministry on Wednesday and is confident of a favourable resolution for them.

The centre added that it is ready to intervene and provide further assistance to the workers, should the need arise.

STORY HIGHLIGHTS


  • The report cites "management deficiencies" at high levels of the State Department

  • It concludes "there was no protest prior to the attacks" on September 11

  • Staffing for the Bureau of Diplomatic Security was "inadequate," report says




Washington (CNN) -- An independent review of the September 11 attacks on the U.S. Consulate in Benghazi released Tuesday cited "systemic failures and leadership and management deficiencies" at the State Department.


The attacks killed four Americans, including U.S. Ambassador J. Christopher Stevens.


The failures resulted in a security plan "that was inadequate for Benghazi and grossly inadequate to deal with the attack that took place," the 39-page, unclassified version of the report concluded.


Read the independent panel's full report


Veteran diplomat Thomas Pickering and former Joint Chiefs of Staff Chairman Adm. Mike Mullen, both members of the review board, are scheduled to brief members of the House Foreign Affairs and Senate Foreign Relations committees in private on Wednesday.








The board cited a lack of resources as at least partly to blame.


"The solution requires a more serious and sustained commitment from Congress to support State Department needs," it said.


The board found that Washington tended "to overemphasize the positive impact of physical security upgrades ... while generally failing to meet Benghazi's repeated requests" to beef up personnel.


The board completed its investigation this week and sent a copy Monday to Secretary of State Hillary Clinton, who said in letters to the heads of those committees that she accepted every one of its 24 recommendations. They include strengthening security, adding fire-safety precautions and improving intelligence collection in high-threat areas.


The report said "there was no protest prior to the attacks," which it described as "unanticipated in their scale and intensity."


It also cited the Bureau of Diplomatic Security staff as "inadequate" in Benghazi on the day of the attack and in the months and weeks leading up to it, "despite repeated requests from Special Mission Benghazi and Embassy Tripoli for additional staffing."


The report said there had been a "lack of transparency, responsiveness, and leadership at the senior levels" in Washington, Tripoli and Benghazi.


"Security in Benghazi was not recognized and implemented as a 'shared responsibility' by the bureaus in Washington charged with supporting the post, resulting in stove-piped discussions and decisions on policy and security," it said. "That said, Embassy Tripoli did not demonstrate strong and sustained advocacy with Washington for increased security for Special Mission Benghazi."


The report said the short-term nature of the mission's staff, many of whom were inexperienced U.S. personnel, "resulted in diminished institutional knowledge, continuity and mission capacity."


The mission was also "severely under-resourced with regard to certain needed security equipment," it said.


It singled out for criticism the dependence on "poorly skilled" members of the Libyan February 17 Martyrs' Brigade and unarmed local guards who were supposed to provide security. It noted that, at the time of Stevens' visit, militia members "had stopped accompanying Special Mission vehicle movements in protest over salary and working hours."


Though it said there had been no specific, credible threats on the day of the attack, the significance of the anniversary of the 9/11 terror attacks in 2001 had led Stevens to decide to hold meetings on the compound on September 11 of this year.


But security systems and the Libyan response "fell short" when the compound came was penetrated "by dozens of armed attackers."


The report offers a detailed description of what happened that night. It said Libyan mission guards were not present, local militia fled their posts and "there simply was not enough time for armed U.S. military assets to have made a difference."


The board said it could not determine how a gate at the compound was breached, "but the speed with which attackers entered raised the possibility" that the guards had left it open.


Eric Boswell, assistant secretary of state for diplomatic security, and Charlene Lamb, deputy assistant secretary of state for international programs, oversaw decisions on security at the diplomatic outpost. Lamb testified before Congress about the security precautions. Documents show Lamb denied repeated requests for additional security in Libya.


Despite all the criticism, the board found no U.S. government employee had engaged in misconduct or ignored responsibilities and did not recommend any individual be disciplined.


Clinton, who is recovering from a stomach virus and concussion, ordered the review in the aftermath of the attack. Such reports are mandated by Congress when Americans working on behalf of the U.S. government are killed overseas.


State Department: Clinton not dodging Benghazi hearings


A notice sent to State Department employees said the implementation team had met Tuesday and would continue to do so regularly to carry out the board's recommendations.


The politics surrounding the events that led to the report have claimed one political casualty, with Susan Rice, U.S. ambassador to the United Nations, last week pulling her name from consideration to succeed Clinton. Some Republican senators had said they would put a hold on her nomination if President Barack Obama had submitted it, based on comments Rice made in the days after the attack.


In place of Clinton, Deputy Secretaries of State William Burns and Thomas Nides will testify before the House and Senate committees Thursday.

Texas school district encourages armed teachers for protection

HARROLD, Texas -- There's at least one school that welcome firearms to class.

It believes nothing makes a school safer than teachers who are armed,

The Harrold Independent School District is one building with 103 students. It's 20 minutes away from the nearest sheriff's station. Superintendent David Thweatt created what he calls a "guardian plan" after the attack at Virginia Tech.

"These people that go in and do these horrible acts, they're evil. But they're not that crazy -- they always know where they are going to get resistance," Thweatt said.

NRA promises "meaningful contributions" to avert another Newtown
The Newtown shootings, as they happened
Complete Coverage: Elementary School Rampage

Teachers and administrators here carry concealed handguns. They won't say how many faculty members are armed. They get extra training, but the district would not give us details.

Some people are horrified when he starts talking about putting guns in schools with children, but Thweatt said it's important to be safe.

"Sure, but it's a pretty horrific thing that happened the other day." Thweatt said. "And quite a few people are not horrified. Quite a few people we have in our district, since we have a high-transfer district, people bring their students to us for that protection."

Texas law allows concealed weapons in schools with a district's permission. Harrold was the first district to do it. A similar proposal was vetoed by Michigan's governor Tuesday.

Thweatt says allowing the firearms into the school will dissuade anyone who wants to hurt the kids.

"That's the bottom line," he said.

Since the shootings in Connecticut, Superintendent Thweatt has gotten calls from districts around the state and as far away as Missouri from school administrators asking whether they might be able to implement similar plans.

Newtown Settles In for Prayerful, Somber Christmas













Residents of Sandy Hook, Conn., gather every year under an enormous tree in the middle of town to sing carols and light the tree. The tree is lit this year, too, but the scene beneath it is starkly different.


The tree looms over hundreds of teddy bears and toys, but they are for children who will never receive them. The ornaments are adorned with names and jarringly recent birth dates.


Wreaths with pine cones and white ribbons hang near the tree, one each for a life lost. A small statue of an angel child sleeps among a sea of candles.


A steady flow of well-wishers, young and old, tearfully comes to cry, pray, light candles, leave gifts and share hugs and stories.


CLICK HERE for complete coverage of the massacre at Sandy Hook.


The Christmas season is a normally joyful time for this tight-knit village, but in the wake of a shooting rampage, holiday decorations have given way this year to memorial signs. And instead of cars with Christmas trees on top, there are media vans with satellites.


Connie Koch has lived in Newtown for nine years. She lives directly behind Sandy Hook Elementary School, where Adam Lanza, 20, killed 20 children and six adults before turning the gun on himself. Earlier that Friday morning, he had also killed his mother at home.

Koch said the shocked town, which includes the Village of Sandy Hook, is experiencing a notably different Christmas this year.


"It's more somber, much more time spent in prayer for our victims' families and our friends that have lost loved ones," she said as she stood near the base of the tree.


CLICK HERE for a tribute to the shooting victims.


Her family has been touched by the tragedy is multiple ways.


"My daughter, she lost her child that she babysat for for six years," she said, holding back tears. "And for her friend who lost her mother. And for my dear friend who lost one of her friends in the school, one of the aides.


"It's hard. And there will be much prayer on Christmas morning for these people, for our community."


Koch said her community always rallies in the face of tragedy, but the term "hits close to home" resonates this time more than ever before. She says the only way to make it through is one day at a time.


"It's all you can do, one hour at a time," Koch said. "For me, I don't even want to wake up in the morning because I don't want to have to face it again. You feel like it's still just a dream and with the funerals starting, it's becoming more real. It's becoming more final."


Another Newtown parent, Adam Zuckerman, stood by the makeshift memorial with a roll of red heart stickers with the words, "In Our" above a drawing of the Sandy Hook Elementary School welcome sign. He was selling the stickers to collect money for a Sandy Hook victims' fund.


"It's a lot," he said of the events of the past few days. "We don't know how it's going to affect our community, but I feel very strongly that I needed to do something to keep it positive, to keep this community positive."


Zuckerman's 20-year-old stepdaughter came home from college for winter break the night before the shooting. As a high school student, she worked in one of the town's popular toy stores.


"She knew a lot of the kids," he said of his daughter. "Their parents brought them in over the years. We have other friends who have lost family here and good friends who are dear friends with the principal of the school. … It's pretty rough."

Fungal frog killer hops into crayfish








































Crayfish are vulnerable to the same fungus that is killing frogs all over the world. The discovery helps explain how the disease spreads even after all the amphibians in an area have been wiped out. Worryingly, chemicals released by the fungus may alone be enough to kill.












Taegan McMahon of the University of South Florida, Tampa, and colleagues discovered infected crayfish in field surveys in Louisiana and Colorado. They found that up to 29 per cent of the animals carried the chytrid fungus Batrachochytrium dendrobatidis. Lab studies proved that crayfish can become infected and die, the first time this has been shown in non-amphibians.













Infected crayfish can pass the disease to tadpoles, and crayfish exposed to water from which the fungus had been filtered still died. McMahon says the distribution of crayfish around the world may explain why the fungus is so widespread.












She adds that it is "is certainly possible" that other invertebrates might carry the fungus. Her team are currently investigating this and are working on possible ways to stop the spread of the toxin.












"It's very compelling, their evidence for crayfish as a disease vector and for a toxic effect secreted in the water," says Trenton Garner at London's Institute of Zoology.

Indonesia blames pilot error for plane crash that killed 45






JAKARTA: Indonesian investigators blamed pilot error on Tuesday for a Sukhoi Superjet crash that killed all 45 onboard an exhibition flight that slammed into a Javanese volcano in May.

The National Transport Safety Committee (KNKT) found that the terrain awareness and warning system (TAWS) was functioning and that the pilot had switched it off before the crash.

"The TAWS had sent a 'terrain ahead' warning before the crash, followed by six 'avoid terrain' warnings. The pilot in command switched the TAWS off as he assumed there was a database problem," KNKT chief Tatang Kurniadi said.

He said there was a "diversion of attention" in the cockpit before the Sukhoi Superjet 100 crashed into the 7,200-foot (2,200-metre) dormant Mount Salak volcano.

"The crash could have been avoided if a recovery action was carried out within 24 seconds from the first warning," he told reporters.

The flight was scheduled to be a 40-minute hop to showcase the new Russian plane to prospective buyers in Indonesia, where the aviation industry is booming.

The Superjet accident was taken as a blow to the Russian aviation industry, which was hoping the twin-engine plane, the first new civilian aircraft built in post-Soviet Russia, would improve its image.

Obama moves on taxes in latest "cliff" counter-proposal

President Obama gave up Monday on his demand for higher taxes on households earning $250,000 and upped it to $400,000 while embracing smaller cost-of-living Social Security raises in a counter-proposal to House Speaker John Boehner meant to narrow differences and forge a pre-Christmas "fiscal cliff" deal.

Mr. Obama and Boehner met for nearly an hour in the Oval Office on Monday and sources familiar with the talks released specific details of the White House proposal.

Boehner aides said it brought the two sides closer but said a deal was not at hand.

"Any movement away from the unrealistic offers the President has made previously is a step in the right direction, but a proposal that includes $1.3 trillion in revenue for only $930 billion in spending cuts cannot be considered balanced," said Brendan Buck, a Boehner spokesman.

Other senior Republican aides told reporters on Capitol Hill they are not rejecting the latest White House offer, but they also said that there is not parity or balance in the White House plan and substantive issues remain unresolved. One senior aide said the issues that they are talking about are not technically difficult to resolve, but they were wary the differences might be fundamental issues that are difficult to resolve.


But the depth, specificity and fine-grain nature of discussions over policy, tax revenue and spending cuts belied the tough rhetoric from the two sides in the negotiation. Signs point to a deal before the New Year's fiscal cliff deadline -- and possibly an announcement as early as Wednesday.

Boehner's "fiscal cliff" concessions come with a price



Talks picked up genuine momentum on Friday when Boehner agreed to higher income tax rates on households earning $1 million and above. Previously, Boehner opposed all income tax increases. He also gave in on raising the debt ceiling, a vote some Republicans wanted to use as leverage against Obama in 2013. Both gestures, top White House aides said, broke the logjam.

Mr. Obama responded with big concessions of his own on Monday. He offered a $400,000 income threshold for a Clinton-era top tax bracket of 39.6 percent. Boehner had proposed that tax rate for millionaires and a total 10-year tax revenue figure of $1 trillion. Obama wants $1.2 trillion in new revenue. Both sides look for hundreds of billions in new revenue in 2013 through a tax reform process that eliminates some tax deduction and closes loopholes.


The president also wants a two-year ceasefire on raising the debt ceiling. Boehner offered one year.


In addition to disagreement on income levels for tax rates or some other way to get more revenue, the two sides have not set in stone an actual tax reform process. It sounds like they are talking about creating a new sequester-like mechanism in 2014 as incentive for both tax reform and entitlement reforms.


Speaking of entitlements, Boehner also asked the White House to increase the eligibility age for Medicare but Mr. Obama again refused. This difference could loom large as Republicans want structural cost-saving changes in Medicare in exchange for raising income tax rates.

Mr. Obama has given ground on cost-of-living adjustments to Social Security and other federal benefits, but is trying to shield Medicare. Democrats have warned Obama they might bolt if he folds on raising Medicare's eligibility age. They have been less emphatic about cost-of-living adjustments.

Other components of the president's counter-proposal include:


  • $1.2 trillion in new income tax revenue with a 39.6 percent (up from 35 percent) on income of $400,000 or more.
  • $1.2 trillion in spending cuts divided this way: $800 billion in cuts; $290 billion in interest savings due to lower deficits; $130 billion in cost-of-living adjustments - - with specific protections to preserve increases for economically disadvantaged beneficiaries. Because changing cost-of-living adjustments would also affect where people fell in various tax brackets, this move would raise $90 billion
  • The $800 billion in cuts would come from $400 billion in savings to health care entitlements like Medicare and Medicaid; $200 billion in better tax revenue collection, increased financial transaction fees and reduced federal employee benefits.
  • $200 billion in domestic discretionary -- annual spending on basic government functions - divided equally between defense and non-defense programs.
  • At least $50 billion devoted next year to infrastructure spending and more in latter years - figures still subject to negotiation.
  • A one-year extension of unemployment insurance benefits.

Both sides have already agreed to create long-term solutions for the annual ritual of adjusting the Alternative Minimum Tax, the reimbursement formulas for Medicare physicians and a grab-bag of pro-business tax breaks.

Obama also did not ask for an extension of the temporary 2 percent payroll tax - a priority for some Democrats.

Funding for Superstorm Sandy will be handled separately from the emerging fiscal cliff package. The Senate is considering the administration's $60.4 billion request and the White House expects swift, bipartisan approval.

CBS News Capitol Hill producer Jill Jackson contributed to this report.

Conn. Kids Laid to Rest: 'Our Hearts Are With You'













Visibly shaken attendees exiting the funeral today for 6-year-old Noah Pozner, one of 20 children killed in the Connecticut school massacre last week, said they were touched by a story that summed up the first-grader best.


His mother, Veronique, would often tell him how much she loved him and he'd respond: "Not as much as I [love] you," said a New York man who attended the funeral but was not a member of the family.


Noah's family had been scheduled to greet the public before the funeral service began at 1 p.m. at the Abraham L. Green & Son Funeral Home in Fairfield, Conn. The burial was to follow at the B'nai Israel Cemetery in Monroe, Conn. Those present said they were in awe at the composure of Noah's mother.


Rabbi Edgar Gluck, who attended the service, said the first person to speak was Noah's mother, who told mourners that her son's ambition when he grew up was to be either a director of a plant that makes tacos -- because that was his favorite food -- or to be a doctor.


Outside the funeral home, a small memorial lay with a sign reading: "Our hearts are with you, Noah." A red rose was also left behind along with two teddy bears with white flowers and a blue toy car with a note saying "Noah, rest in peace."

Sandy Hook Victims: Jack Pinto's Funeral Held Watch Video









First Sandy Hook Shooting Victims to Be Buried Watch Video







The funeral home was adorned with white balloons as members of the surrounding communities came also to pay their respects, which included a rabbi from Bridgeport. More than a dozen police officers were at the front of the funeral home, and an ambulance was on standby at a gas station at the corner.


U.S. Sen. Richard Blumenthal, U.S. Rep. and Sen.-Elect Chris Murphy and Gov. Dannel P. Malloy, all of Connecticut, were in attendance, the Connecticut Post reported.


Noah was an inquisitive boy who liked to figure out how things worked mechanically, The Associated Press reported. His twin sister, Arielle, was one of the students who survived when her teacher hid her class in the bathroom during the attack.


CLICK HERE for a tribute to the shooting victims.


The twins celebrated their sixth birthday last month. Noah's uncle Alexis Haller told the AP that he was "smart as a whip," gentle but with a rambunctious streak. He called his twin sister his best friend.


"They were always playing together, they loved to do things together," Haller said.


The funeral for Jack Pinto, 6, was also held today, at the Honan Funeral Home in Newtown. He was to be buried at Newtown Village Cemetery.


Jack's family said he loved football, skiing, wrestling and reading, and he also loved his school. Friends from his wrestling team attended his funeral today in their uniforms. One mourner said the message during the service was: "You're secure now. The worst is over."


Family members say they are not dwelling on his death, but instead on the gift of his life that they will cherish.


The family released a statement, saying, Jack was an "inspiration to all those who knew him."


"He had a wide smile that would simply light up the room and while we are all uncertain as to how we will ever cope without him, we choose to remember and celebrate his life," the statement said. "Not dwelling on the loss but instead on the gift that we were given and will forever cherish in our hearts forever."


Jack and Noah were two of 20 children killed Friday morning at Sandy Hook Elementary School in Newtown, Conn., when 20-year-old Adam Lanza sprayed two first-grade classrooms with bullets that also killed six adults.
