Iran claims shooting down two US-made RQ-11 drones

TEHRAN: Iran on Wednesday said it had shot down two US-made RQ-11 reconnaissance drones in the past 15 months, adding to a ScanEagle drone and RQ-170 Sentinel stealth aircraft it already claims to have captured.

"The army's air defence shot down two... RQ-11 drones," Rear Admiral Amir Rastegari told state television and Fars news agency, adding that the army was carrying out "research" on the downed unmanned aircraft.

He said the first had been brought down in August to September 2011 and the second in October to November 2012, but gave no details of their location.

He did not offer proof for the claim.

Iran has in the past claimed to have hunted down a number of US drones, showing detailed images of the alleged spoils.

In December it said it had captured a small US ScanEagle drone in its airspace above the Gulf, which the US navy denied.

A year before that, it claimed to have captured a much bigger and more sophisticated CIA stealth drone, an RQ-170 Sentinel.

The AeroVironment RQ-11 type aircraft that Rastegari said had been shot down is a small, hand-launched and remote-controlled drone used by US military intelligence, and has also been adopted by some US allies.

It has a range of over 10 kilometres and can fly at up to 95 kilometres per hour for 80 minutes.

Rastegari made the announcement after a six-day Iranian naval exercise in the Gulf of Oman and the Strait of Hormuz, through which a third of the world's marketed oil passes.

Several surface-to-air missiles were fired as part of the manoeuvres, according to Iranian media.

Bombay HC asks Centre to file reply on Sadhvi Pragya's petition challenging validity of NIA

MUMBAI: The Bombay high court has directed the Union government to respond to a petition filed by Sadhvi Pragya Singh Thakur, one of the prime accused in the 2008 Malegaon blast case, challenging the constitutional validity of the National Investigation Agency (NIA).

A division bench of Justice Abhay Oka and justice Sambhaji Shinde have given the Centre time till February 4, 2013 to file its reply.

The Sadhvi had challenged an April 2011 order of the Centre transferring probe in the blasts case to the NIA. The petition claimed that the Union government could not have done so without a nod from the state government.

Claiming that there was a political conspiracy behind the move, the petition said: "NIA does not have retrospective power to re-investigate into those offences where charge sheet has been already filed by state investigating agencies."

The court however questioned whether an accused had any locus standi or right under the law to challenge transfer of investigations.

An RDX bomb had exploded on September 29, 2008 in Malegaon killing six and injuring 101.Twelve persons were arrested in the case, including the Sadhvi and serving Lt. Col. of the Indian Army, Prasad Purohit.

Brain image study: Fructose may spur overeating

This is your brain on sugar — for real. Scientists have used imaging tests to show for the first time that fructose, a sugar that saturates the American diet, can trigger brain changes that may lead to overeating.

After drinking a fructose beverage, the brain doesn't register the feeling of being full as it does when simple glucose is consumed, researchers found.

It's a small study and does not prove that fructose or its relative, high-fructose corn syrup, can cause obesity, but experts say it adds evidence they may play a role. These sugars often are added to processed foods and beverages, and consumption has risen dramatically since the 1970s along with obesity. A third of U.S. children and teens and more than two-thirds of adults are obese or overweight.

All sugars are not equal — even though they contain the same amount of calories — because they are metabolized differently in the body. Table sugar is sucrose, which is half fructose, half glucose. High-fructose corn syrup is 55 percent fructose and 45 percent glucose. Some nutrition experts say this sweetener may pose special risks, but others and the industry reject that claim. And doctors say we eat too much sugar in all forms.

For the study, scientists used magnetic resonance imaging, or MRI, scans to track blood flow in the brain in 20 young, normal-weight people before and after they had drinks containing glucose or fructose in two sessions several weeks apart.

Scans showed that drinking glucose "turns off or suppresses the activity of areas of the brain that are critical for reward and desire for food," said one study leader, Yale University endocrinologist Dr. Robert Sherwin. With fructose, "we don't see those changes," he said. "As a result, the desire to eat continues — it isn't turned off."

What's convincing, said Dr. Jonathan Purnell, an endocrinologist at Oregon Health & Science University, is that the imaging results mirrored how hungry the people said they felt, as well as what earlier studies found in animals.

"It implies that fructose, at least with regards to promoting food intake and weight gain, is a bad actor compared to glucose," said Purnell. He wrote a commentary that appears with the federally funded study in Wednesday's Journal of the American Medical Association.

Researchers now are testing obese people to see if they react the same way to fructose and glucose as the normal-weight people in this study did.

What to do? Cook more at home and limit processed foods containing fructose and high-fructose corn syrup, Purnell suggested. "Try to avoid the sugar-sweetened beverages. It doesn't mean you can't ever have them," but control their size and how often they are consumed, he said.

A second study in the journal suggests that only severe obesity carries a high death risk — and that a few extra pounds might even provide a survival advantage. However, independent experts say the methods are too flawed to make those claims.

The study comes from a federal researcher who drew controversy in 2005 with a report that found thin and normal-weight people had a slightly higher risk of death than those who were overweight. Many experts criticized that work, saying the researcher — Katherine Flegal of the Centers for Disease Control and Prevention — painted a misleading picture by including smokers and people with health problems ranging from cancer to heart disease. Those people tend to weigh less and therefore make pudgy people look healthy by comparison.

Flegal's new analysis bolsters her original one, by assessing nearly 100 other studies covering almost 2.9 million people around the world. She again concludes that very obese people had the highest risk of death but that overweight people had a 6 percent lower mortality rate than thinner people. She also concludes that mildly obese people had a death risk similar to that of normal-weight people.

Critics again have focused on her methods. This time, she included people too thin to fit what some consider to be normal weight, which could have taken in people emaciated by cancer or other diseases, as well as smokers with elevated risks of heart disease and cancer.

"Some portion of those thin people are actually sick, and sick people tend to die sooner," said Donald Berry, a biostatistician at the University of Texas MD Anderson Cancer Center in Houston.

The problems created by the study's inclusion of smokers and people with pre-existing illness "cannot be ignored," said Susan Gapstur, vice president of epidemiology for the American Cancer Society.

A third critic, Dr. Walter Willett of the Harvard School of Public Health, was blunter: "This is an even greater pile of rubbish" than the 2005 study, he said. Willett and others have done research since the 2005 study that found higher death risks from being overweight or obese.

Flegal defended her work. She noted that she used standard categories for weight classes. She said statistical adjustments were made for smokers, who were included to give a more real-world sample. She also said study participants were not in hospitals or hospices, making it unlikely that large numbers of sick people skewed the results.

"We still have to learn about obesity, including how best to measure it," Flegal's boss, CDC Director Dr. Thomas Frieden, said in a written statement. "However, it's clear that being obese is not healthy - it increases the risk of diabetes, heart disease, cancer, and many other health problems. Small, sustainable increases in physical activity and improvements in nutrition can lead to significant health improvements."

Lawmakers Furious at Boehner Over Sandy 'Betrayal'

Republican lawmakers from New York and New Jersey whose storm-ravaged residents are desperate for federal aid are fuming at their party's leaders for refusing to hold a vote on a $60 billion disaster relief package despite promises that help was on the way.

"This was a betrayal," Rep. Michael Grimm, R-N.Y., told ABC News.com. "It's just reprehensible. It's an indefensible error in judgment not have given relief to these people that are so devastated."

New Jersey Gov. Chris Christie, a Republican, called it a "dereliction of duty" in a joint statement with New York Gov. Andrew Cuomo, a Democrat.

"This failure to come to the aid of Americans following a severe and devastating natural disaster is unprecedented," the governors said.

Lawmakers were told by Speaker John Boehner, R-Ohio, that the relief bill would get a vote on Tuesday night following an eleventh hour vote on the fiscal cliff bill. But in an unexpected switch, Boehner refused to put the relief bill to a vote, leading to lawmakers from parties yelling on the floor of the House.

Congress historically has responded to natural disasters by promptly funding relief efforts. The Senate already passed its version of the bill that would replenish an emergency fund set to run out of cash next week and which will help repair subways and tunnels in New York City and rebuild parts of the New Jersey shore devastated by superstorm Sandy.

Time is particularly pressing, given that a new Congress will be sworn in Thursday. The Senate will therefore have to vote on the bill again before it comes to the House, which could be as late as February or March.

'Fiscal Cliff' Deal Passes House Despite GOP Holdouts Watch Video

Rep. Peter King, R- N.Y., took the floor of the House and to the airwaves and aimed his outrage squarely at Boehner, accusing him plunging "a cruel knife in the back" of storm-ravaged residents "who don't have shelter, don't have food," he said during a House session this morning.

"This is not the United States. This should not be Republican Party. This shouldn't not be the Republican leadership," King said on the floor of the House.

He made no attempt to hide his anger, suggesting that residents in New York and New Jersey should stop sending money to Republicans and even questioning aloud whether he could remain a member of the party.

"Anyone who donates one cent to the Republican Congressional Campaign Committee should have their head examined," King, a staunch conservative and Republican congressman for 10 years, told CNN.

"They have written off New York and New Jersey. They've written me off…. Party loyalty, I'm over that. When your people are literally freezing in the winter… Then why should I help the Republican Party?" he added.

He said that Boehner refused to talk to Republican members from New York and New Jersey when they tried to ask him about the vote Tuesday night.

"He just decided to sneak off in the dark of night," King said.

Democrats were also outraged.

"It is truly heartless that the House will not even allow the Sandy bill to come to the floor for a vote, and Speaker Boehner should reconsider his ill advised decision," Sen. Chuck Schumer, D- N.Y., said in a statement.

October's storm was the worst natural disaster ever to hit the region, causing billions in damage and leaving 120 people dead.

More than 130,000 people are expected to make claims to the federal government, but without a funding increase only about 12,000 people can be covered with existing funds.

"It doesn't make sense they wouldn't vote on this. There are truly people in need," said Steve Greenberg, whose home was flooded and damaged by fire in the hard-hit Breezy Point section of Queens. "Not of these people are fit to serve," he said.

Grimm said Boehner's decision fuels a perception that the Republican Party does not care about people.

"It buys into the ideology that Republicans don't care and are callous," he said. Grimm said there were enough votes to get the bill passed and that it makes fiscal sense, because the money would go to help spur small businesses.

About 60 crushed to death in Ivory Coast stampede

ABIDJAN (Reuters) - About 60 people were crushed to death in a stampede outside a stadium in Ivory Coast's main city of Abidjan after a New Year's Eve fireworks display, the government said on Tuesday.

The incident took place near Felix Houphouet Boigny Stadium where a crowd had gathered to watch fireworks, emergency officials said.

One of the injured, speaking to Reuters at a hospital, said security forces had arrived to break up the crowd, triggering a panic in which many people fell over and were trampled.

"The provisional death toll is 60 and there are 49 injured," Interior Minister Hamed Bakayoko said in a statement broadcast on national television.

President Alassane Ouattara, visiting injured people at the hospital, called the incident a national tragedy and said an investigation was underway to determine what happened.

A Reuters correspondent said blood stains and abandoned shoes littered the scene outside the stadium on Tuesday morning.

"My two children came here yesterday. I told them not to come but they didn't listen. They came when I was sleeping. What will I do?" said Assetou Toure, a cleaner.

She did not know if her children had escaped unhurt.

The incident was the worst of its kind in Abidjan since 2010, when a stampede at a stadium during a football match killed 18 people.

Ivory Coast, once a stable economic hub for West Africa, is struggling to recover from a 2011 civil war in which more than 3,000 people were killed.

Football: United start 2013 with bang to keep City at bay

LONDON: Manchester United kept a firm grip on the Premier League title race by sweeping to a 4-0 win at Wigan Athletic on the first day of 2013 to maintain their seven-point lead.

Champions Manchester City remain United's nearest rivals after a 3-0 success at home to Stoke City, while Tottenham Hotspur climbed to third by coming from behind to defeat second-bottom Reading 3-1 at White Hart Lane.

Javier Hernandez had already had a goal ruled out for offside at the DW Stadium when he put United 1-0 up against Wigan by tapping in after Ali Al Habsi saved from Patrice Evra in the 35th minute.

Robin van Persie got off the mark for the New Year eight minutes later, collecting a pass from Hernandez and sending Ivan Ramis to the turf with a dummy before curling the ball inside the right-hand post.

Hernandez added a third in the 63rd minute, swivelling to dispatch a half-volley when a van Persie free-kick arrived at his feet, before the Dutchman completed a brace of his own in the 88th minute with his 16th league goal.

City dominated the early stages at home to Stoke, who had gone into the game looking to protect a 10-match unbeaten run.

Pablo Zabeleta broke the deadlock two minutes before half-time, rolling the ball into an empty net after Asmir Begovic touched away James Milner's low cross with his foot.

Sergio Aguero was the creator of City's second in the 56th minute, with a low drive that was parried by Begovic, only for Edin Dzeko to turn the loose ball home.

Aguero scored a 74th-minute penalty after Steven Nzonzi was adjudged to have tripped David Silva, but the Argentine had to leave the fray moments later after appearing to sustain a hamstring injury.

Tottenham fell behind in the fourth minute against Reading when Pavel Pogrebnyak headed the visitors in front, but Michael Dawson's header meant the hosts were level within five minutes.

Spurs were dominant from then on, Emmanuel Adebayor putting them in front with a powerful 51st-minute header before Clint Dempsey's fortuitous deflected strike made it 3-1.

Victory took Spurs a point clear of Chelsea, who have two games in hand and host bottom club Queens Park Rangers on Wednesday.

Aston Villa put an end to a run of three straight defeats, in which they had conceded 15 goals, by drawing 2-2 at Swansea City, who equalised through Danny Graham in injury time.

Christian Benteke had put Villa ahead with an 84th-minute penalty, after Wayne Routledge's ninth-minute opener for the hosts had been cancelled out by Andreas Weimann.

West Ham United were also on the up, beating Norwich City 2-1 through goals from Mark Noble and Joey O'Brien to climb to 11th.

Earlier, Fulham shook off their slumbers from 2012 to win 2-1 at West Bromwich Albion and record only their second win in 13 matches.

Fulham striker Dimitar Berbatov had the honour of scoring the first goal of 2013 at the Hawthorns, with Alex Kacaniklic netting a 58th-minute winner after Romelu Lukaku equalised early in the second half.

Fifth-place Arsenal, 7-3 victors against Newcastle United on Saturday, visit Southampton in the evening kick-off.

Tapping diverse energy sources remains govt’s top priority

NEW DELHI: Energy will continue to be a top priority for the government in the coming months as India scrambles to increase access to its more and diversified sources.

In the immediate future, the government is likely to concentrate on a few things. First, the government's new investment committee will be asked to take a decision on exploration in gas blocks that had been held up due to defence and space departments' objections. Second, push the US government to allow more shale gas exports to India. Third, India will continue to focus on coal, and countries like Australia and Indonesia will become more important as India imports more coal for power generation than the current imports of largely coking coal.

The government is looking at unfreezing exploration projects in over 11 onshore and offshore gas blocks — these have been held up due to objections by the Navy, IAF, DRDO and the department of space. "Either it is a practice area, or in the flight path of missile tests ... other countries have overcome these clearance hurdles, we should be able to do so," said officials involved in the decision. Since these decisions cannot be taken at the official level, the newly-formed cabinet committee will be tasked with clearing these projects so major foreign companies don't exit the exploration sector.

US' shale gas exports to India are a priority for the government. With the US heading to becoming a global leader in shale gas, India wants to be one of the bigger importers (South Korea is the largest importer of the gas). This is a slightly tricky process, made difficult by the fact that India is not US' FTA partner. The US' department of energy has recently published an internal study of the impact gas sales would have on American domestic energy sector. This study will influence the Congress's decision to open up gas exports to India as being in national interest.

The decision will not be easy: chemical industries and companies returning manufacturing to the US by taking advantage of low prices are likely to oppose exports on the grounds that this might raise gas prices internally.

Coal will remain India's primary energy source for power. Therefore, Australia and Indonesia are likely to become more important as energy suppliers for India. In a new study, Worldwatch Institute says, though oil remains the world's leading energy source, coal and natural gas continue to grow in significance. The study says, "spurred mainly by rising demand in China and India, coal's share in the global primary energy mix reached 28% in 2011— its highest point since 1971."

The study goes on, "China alone accounted for nearly half of all coal use in 2011. India is the second largest contributor to rising coal demand and is the world's third largest coal consumer, after surpassing the European Union in 2009. The United States remains the second largest coal user, even though the US' demand decreased by around 5% in 2011 and continued to fall in 2012 due to the shale gas boom and the abundance of cheap natural gas."

Clinton receiving blood thinners to dissolve clot

WASHINGTON (AP) — Doctors treating Secretary of State Hillary Rodham Clinton for a blood clot in her head said blood thinners are being used to dissolve the clot and they are confident she will make a full recovery.

Clinton didn't suffer a stroke or neurological damage from the clot that formed after she suffered a concussion during a fainting spell at her home in early December, doctors said in a statement Monday.

Clinton, 65, was admitted to New York-Presbyterian Hospital on Sunday when the clot turned up on a follow-up exam on the concussion, Clinton spokesman Phillipe Reines said.

The clot is located in the vein in the space between the brain and the skull behind the right ear. She will be released once the medication dose for the blood thinners has been established, the doctors said.

In their statement, Dr. Lisa Bardack of the Mount Kisco Medical Group and Dr. Gigi El-Bayoumi of George Washington University said Clinton was making excellent progress and was in good spirits.

Clinton's complication "certainly isn't the most common thing to happen after a concussion" and is one of the few types of blood clots in the skull or head that are treated with blood thinners, said Dr. Larry Goldstein, a neurologist who is director of Duke University's stroke center. He is not involved in Clinton's care.

The area where Clinton's clot developed is "a drainage channel, the equivalent of a big vein inside the skull. It's how the blood gets back to the heart," Goldstein said.

Blood thinners usually are enough to treat the clot and it should have no long-term consequences if her doctors are saying she has suffered no neurological damage from it, Goldstein said.

Clinton returned to the U.S. from a trip to Europe, then fell ill with a stomach virus in early December that left her severely dehydrated and forced her to cancel a trip to North Africa and the Middle East. Until then, she had canceled only two scheduled overseas trips, one to Europe after breaking her elbow in June 2009 and one to Asia after the February 2010 earthquake in Haiti.

Her condition worsened when she fainted, fell and suffered a concussion while at home alone in mid-December as she recovered from the virus. It was announced Dec. 13.

This isn't the first time Clinton has suffered a blood clot. In 1998, midway through her husband's second term as president, Clinton was in New York fundraising for the midterm elections when a swollen right foot led her doctor to diagnose a clot in her knee requiring immediate treatment.

Clinton had planned to step down as secretary of state at the beginning of President Barack Obama's second term. Whether she will return to work before she resigns remained a question.

Democrats are privately if not publicly speculating: How might her illness affect a decision about running for president in 2016?

After decades in politics, Clinton says she plans to spend the next year resting. She has long insisted she had no intention of mounting a second campaign for the White House four years from now. But the door is not entirely closed, and she would almost certainly emerge as the Democrat to beat if she decided to give in to calls by Democratic fans and run again.

Her age — and thereby health — would probably be a factor under consideration, given that Clinton would be 69 when sworn in, if she were elected in 2016. That might become even more of an issue in the early jockeying for 2016 if what started as a bad stomach bug becomes a prolonged, public bout with more serious infirmity.

Not that Democrats are willing to talk openly about the political implications of a long illness, choosing to keep any discussions about her condition behind closed doors. Publicly, Democrats reject the notion that a blood clot could hinder her political prospects.

"Some of those concerns could be borderline sexist," said Basil Smikle, a Democratic strategist who worked for Clinton when she was a senator. "Dick Cheney had significant heart problems when he was vice president, and people joked about it. He took the time he needed to get better, and it wasn't a problem."

It isn't uncommon for presidential candidates' health — and age — to be an issue. Both in 2000 and 2008, Sen. John McCain, R-Ariz., had to rebut concerns he was too old to be commander in chief or that his skin cancer could resurface.

Two decades after Clinton became the first lady, signs of her popularity — and her political strength — are ubiquitous.

Obama had barely declared victory in November when Democrats started zealously plugging Clinton as their strongest White House contender four years from now, should she choose to take that leap.

"Wouldn't that be exciting?" House Democratic leader Nancy Pelosi declared in December. "I hope she goes. Why wouldn't she?"

Even Republicans concede that were she to run, Clinton would be a force to be reckoned with.

"Trying to win that will be truly the Super Bowl," Newt Gingrich, the former House Speaker and 2012 GOP presidential candidate, said in December. "The Republican Party today is incapable of competing at that level."

Americans admire Clinton more than any other woman in the world, according to a Gallup poll released Monday — the 17th time in 20 years that Clinton has claimed that title. And a recent ABC News/Washington Post poll found that 57 percent of Americans would support Clinton as a candidate for president in 2016, with just 37 percent opposed. Websites have already cropped up hawking "Clinton 2016" mugs and tote bags.

Beyond talk of future politics, Clinton's three-week absence from the State Department has raised eyebrows among some conservative commentators who questioned the seriousness of her ailment after she canceled planned Dec. 20 testimony before Congress on the deadly attack on the U.S. diplomatic mission in Benghazi, Libya.

Clinton had been due to discuss with lawmakers a scathing report she had commissioned on the attack. It found serious failures of leadership and management in two State Department bureaus were to blame for insufficient security at the facility. Clinton took responsibility for the incident before the report was released, but she was not blamed. Four officials cited in the report have either resigned or been reassigned.

White House Revels in Fiscal Cliff 'Victory'

Jan 1, 2013 12:13pm

It’s hard to find anyone in Washington happy about the outcome of the “fiscal cliff” brinksmanship.

But inside the Obama White House, senior officials are elated by what they call a significant presidential achievement:  breaking longstanding Republican intransigence on taxes.

The deal passed by the Senate early this morning, with the endorsement of all but seven of the 47 Republicans, would raise $620 billion in new revenue, hiking tax rates on households earning more than $450,000 a year.

The income tax hike would be the first in two decades.

“Keep in mind that just last month Republicans in Congress said they would never agree to raise tax rates on the wealthiest Americans,” President Obama said Monday. “Obviously, the agreement that’s currently being discussed would raise those rates and raise them permanently.”

The spin from the White House – casting the new revenue as a major victory – is at least partly aimed at grumbling liberals who have accused Obama of capitulating on a key campaign pledge: hiking tax rates on households making $250,000 or more.

“Anyone looking at these negotiations, especially given Obama’s previous behavior, can’t help but reach one main conclusion: Whenever the president says that there’s an issue on which he absolutely, positively won’t give ground, you can count on him, you know, giving way – and soon, too,” liberal economist Paul Krugman wrote today in the New York Times.

“The idea that you should only make promises and threats you intend to make good on doesn’t seem to be one that this particular president can grasp.”

Still, the White House believes the concessions Obama extracted from Republicans on taxes puts him in a stronger position for negotiating on the debt ceiling and “sequester” in the coming weeks.

The president now says any deal to offset the automatic “sequester” spending cuts will have to be balanced – including additional new tax revenue, not cuts alone.

But Republican leaders see the outcome, and the fiscal fights ahead, much differently.

GOPers are touting permanent extension of many of the Bush-era tax cuts as a victory in its own right. They also believe the resolution of the tax revenue debate will allow for greater focus on spending cuts and entitlement overhaul, essentially resetting the national dialogue.

“Frankly, we’ve denied [Obama], I think, his most important piece of leverage in any negotiation going forward,” Rep. Tom Cole, R-Okla., who sits on the House Budget Committee, said on MSNBC. “So I particularly like that part.

“The sequester is in front of us. The continuing resolution runs out the end of March and, obviously, the debt ceiling. All of those things honestly are Republican leverage, not Democratic,” he said.

“So I think there will be opportunities to deal with the spending issue next year.”

Senate report faults State Department, intelligence on Benghazi

WASHINGTON (Reuters) - The State Department's decision to keep the U.S. mission in Benghazi open despite inadequate security and increasingly dangerous threat assessments before it was attacked in September was a "grievous mistake," a Senate report said on Monday.

The Senate Homeland Security Committee's report about the September 11 attacks on the U.S. mission and a nearby annex, which killed four Americans, including the U.S. ambassador to Libya, faulted intelligence agencies for not having enough focus on Libyan extremists. It also faulted the State Department for waiting for specific warnings instead of acting on security.

The assessment follows a scathing report by an independent State Department accountability review board that resulted in a top security official and three others at the department stepping down.

The attack, in which U.S. Ambassador Christopher Stevens died, has put diplomatic security practices at posts in insecure areas under scrutiny and raised questions about whether intelligence on terrorism in the region was adequate.

The Senate report said the lack of specific intelligence of an imminent threat in Benghazi "may reflect a failure" in the intelligence community's focus on terrorist groups that have weak or no operational ties to al Qaeda and its affiliates.

"With Osama bin Laden dead and core al Qaeda weakened, a new collection of violent Islamist extremist organizations and cells have emerged in the last two to three years," the report said. That trend has been seen in the "Arab Spring" countries undergoing political transition or military conflict, it said.

The report recommended that U.S. intelligence agencies "broaden and deepen their focus in Libya and beyond, on nascent violent Islamist extremist groups in the region that lack strong operational ties to core al Qaeda or its main affiliate groups."

Neither the Senate report nor the unclassified accountability review board report pinned blame for the Benghazi attack on a specific group. The FBI is investigating who was behind the assaults.

President Barack Obama, in an interview on NBC's "Meet the Press" on Sunday, said the United States had some "very good leads" about who carried out the attacks. He did not provide any details.

The Senate committee report said the State Department should not have waited for specific warnings before acting on improving security in Benghazi.

It also said that it was widely known that the post-revolution Libyan government was "incapable of performing its duty to protect U.S. diplomatic facilities and personnel," but the State Department failed to take adequate steps to fill the security gap.

"Despite the inability of the Libyan government to fulfill its duties to secure the facility, the increasingly dangerous threat assessments, and a particularly vulnerable facility, the Department of State officials did not conclude the facility in Benghazi should be closed or temporarily shut down," the report said. "That was a grievous mistake."
