Fast food linked to child asthma: study

PARIS: Children who frequently eat fast food are far more likely to have severe asthma compared to counterparts who tuck into fruit, a large international study published on Monday said.

Researchers asked nearly half a million teenagers aged 13-14 and children aged six and seven about their eating habits and whether in the previous year they had experienced wheezing, eczema or an itchy, blocked nose when they did not have cold or flu.

The questionnaires -- completed by a parent or guardian for the younger children -- were distributed in scores of countries.

It marks the latest phase in a long-running collaborative programme, the International Study of Asthma and Allergies in Childhood (ISAAC), which was launched in 1991.

The investigators filtered out factors that could skew results, such as maternal smoking during pregnancy, sedentary lifestyle and body-mass index, in order to focus purely on diet.

They found that fast food was the only food type that could be clearly linked to asthma severity.

Three or more weekly servings of fast food were associated with a 39-per cent increase in the risk of severe asthma among teens and a 27-per cent increase among younger children.

It also added to the risk of eczema and severe rhinitis.

In contrast, eating three or more weekly portions of fruit led to a reduction in symptom severity of between 11 and 14 per cent, respectively.

The study, which appears in the British Medical Association journal Thorax, noted that to prove an association is not to prove a cause -- but argued that a further inquiry was clearly needed.

"If the associations (are) causal, then the findings have major public health significance, owing to the rising consumption of fast foods globally," the authors said.

Previous research has found that the saturated and "trans" fatty acids trigger an inflammatory response from the immune system, the paper noted.

Samsung: We've sold 100 million Galaxy S smartphones

Samsung's Galaxy S series smartphones have crossed the threshold of 100 million sales.

According to Samsung's Tomorrow Flickr page, its flagship Galaxy S series has managed to surpass that mark in 2 years and 7 months since the launch of the first Galaxy smartphone in May 2010.

In addition, the firm says that the Galaxy S3 is selling "at [a] much faster rate," smashing through the 1 million barrier in 50 days. Sales of the flagship Galaxy S3 reached 30 million units in 5 months, and 40 million in 7 months, with average daily sales of about 190,000 units. The Galaxy S2 is described as a steady bet after recording sales of over 40 million in 20 months.

Samsung calls the Galaxy series "the driving force" behind the electronics maker's "rise to the top" in the global smartphone market. The firm has estimated that overall sales will reach 56 trillion won ($52.6 billion) in its fourth-quarter results, to be announced on January 25.

It is undeniable that the Galaxy series is popular. According to new research, a number of the younger generation -- Generation Y, if you will -- are branding Samsung phones "cool" in comparison to Apple's offerings. If Samsung products are the ones to own these days, then the recently announced Galaxy S2 Plus, complete with
Android's Jelly Bean operating system, might be the next model in line to surpass the company's sales records.

This news follows a number of announcements made by the South Korean company at the Consumer Electronics Show in Las Vegas last week, including Youm flexible displays and a new eight-core processor for mobile devices.

United Airlines scheme saves millions on fuel taxes: lawsuit

CHICAGO A transportation agency plans to file a lawsuit Monday alleging that United Airlines is falsely claiming to buy huge amounts of jet fuel out of a small, rural Illinois office that doesn't even have a computer to avoid paying tens of millions of dollars in taxes in Chicago, where the purchases are allegedly being made.

The Regional Transportation Authority alleges United Aviation Fuels Corp., a subsidy of United Airlines, has operated a "sham" office in the DeKalb County community of Sycamore since 2001 after reaching an agreement to pay the town more than $300,000 a year -- a fraction of what it would have owed in sales taxes in Chicago and Cook County.

"The only reason that United Fuels has an office in Sycamore is to attempt to create a sham tax situs (location) for fuel sales in a lower taxing jurisdiction," reads a draft of the lawsuit obtained by The Associated Press.

United officials say they have not seen the lawsuit, but that the Sycamore operation is legal.

The RTA, which contends the office has no computer and is staffed by one person who only works part time, said consultants visited the site on a recent weekday and found it locked with nobody inside. The agency said judging from the few chairs and empty desks seen through a window, there is little, if any, business occurring in the office.

"Whoever is out there is not negotiating hundreds of millions of dollars worth of jet fuel," said Jordan Matyas, the RTA's chief of staff. He said any negotiations for fuel, as well as delivery scheduling, accounting, credit approval and administrative decisions, are being done in the Willis Tower in downtown Chicago, where United is headquartered.

The RTA alleges that American Airlines is engaged in a similar "sham" business out of an office it rents in Sycamore's City Hall. But Matyas said American was not included in the lawsuit because the airline remains in bankruptcy, and that suing American would require litigating the case both in federal bankruptcy court in New York and in Cook County Circuit Court, where the RTA plans to file its suit against United. He added that the RTA does plan to pursue legal action against American at some point.

The two airlines are spending a staggering amount of money on fuel. Based on sales taxes that were paid in Sycamore, the RTA estimates that in 2012 alone, the two airlines spent "approximately $1.2 billion on jet fuel the airlines" for jets at O'Hare, Matyas said in an email, adding that it is unclear how much of that was later sold to other airlines.

United officials said they have not received a copy of the complaint, but "believe that any such suit would be without merit."

"In fact, the operation of our fuel subsidiary in Sycamore has been examined by tax authorities in the past and has been determined to comply with all applicable laws," spokeswoman Megan McCarthy said in an email.

American spokeswoman Mary Frances Fagan said in an email that the airline does not comment on pending litigation but added, "What American is doing is permitted under Illinois law."

Sycamore's city manager, Brian Gregory, declined comment.

The RTA said in a prepared statement that "sales tax dodges" have cost the city of Chicago $133 million in lost sales tax revenue since 2005. They have cost Cook County an additional $60 million and Metra, Pace and the Chicago Transit Authority another $96 million, according to the RTA, which oversees the three agencies and relies on sales tax revenue for much of its funding.

"CTA, Metra and Pace have had to work with constrained budgets and have needed to raise fares and reduce service because the money's just not there," RTA executive director Joe Costello said in the news release. "Now we know why."

The lawsuit is potentially embarrassing for Chicago Mayor Rahm Emanuel, who earlier this year called United's decision to move its corporate headquarters to Chicago "great news for all Chicagoans."

When told of the lawsuit, Emanuel spokeswoman Sarah Hamilton said, "The City has been supportive of efforts in Springfield to ensure corporations pay their fair share, but we have not seen this specific lawsuit and therefore cannot comment on it."

According to the RTA, the total sales tax rate in Sycamore is 9.5 percent, compared to 8 percent in Chicago. But the RTA contends the airlines are getting an even better deal: The two companies have entered 25-year agreements that call for Sycamore to "kick back" most of its share of the sales tax on jet fuel, as much as $14 million a year, in exchange for payments of at least $300,000 a year from each airline.

A document provided by the RTA contends that the agreement with United calls for Sycamore to receive $360,000 to $556,000 between 2003 and 2026.

The lawsuit is part of a larger effort by the RTA to combat similar deals between various communities and companies.

The RTA, the city of Chicago and Cook County in 2011 filed lawsuits against Kankakee and the village of Channahon. They alleged that those communities' tax incentive programs are costing other government agencies millions of dollars, because they enable companies to avoid paying higher sales taxes by moving purchases through satellite offices in areas where the sales tax rates are lower.

According to the RTA's lawsuit against Kankakee and Channahon, the agency is owed at least $100 million in lost revenue. The communities contend their programs are legal.

Golden Globe Moments: A Night of Laughs, Surprises

Let's finally bury this idea that women can't be funny once and for all. Fey and Poehler were undeniably hilarious throughout the Globes, so much so that many fans on Twitter demanded more of them during the ceremony. From their opening bit -- Poehler: "Meryl Streep is not here tonight, she has the flu. And I hear she's amazing in it." -- to their pseudo drunk heckling of best TV comedy actress winner Lena Dunham, they were radiant, energetic, and above all, funny. More please.

Foster made her acceptance of the Cecil B. DeMille lifetime achievement award a coming out, of sorts. She first shocked the audience by leading them to think that she was about to make a huge public statement about her sexuality. Instead, she said she was single, adding "I already did my coming out in the stone age."

"Now, apparently, I'm told that every celebrity is expected to honor the details of their private life with a press conference ... You guys might be surprised, but I'm not Honey Boo Boo child," she said, to a flurry of laughter and applause.

"If you had been a public figure from the time that you were a toddler ... then maybe you too might value privacy above all else," she said. "Privacy."

But Foster did specifically thank her ex-partner Cydney Bernard, with whom she has two kids. Both boys gestured to her from the audience.

She also implied that she was retiring from acting when she said she would not be returning to the Globes stage or any stage. "It's just that from now on, I may be holding a different talking stick," Foster said, bringing many in the audience to tears.

But backstage, Foster clarified to reporters that she was not retiring from acting. "Oh that's so funny," she responded to reporters. "You couldn't drag me away. And I'd like to be directing tomorrow."

It takes a lot to make Hollywood star struck. Bill Clinton did it when he strutted on stage to introduce a clip of "Lincoln," which was up for best drama. He brought the crowd of A-listers to its feet and commended the 16th president. "We're all here tonight because he did it," he said of Lincoln's battle to end slavery.

If there was any doubt that Lena Dunham wasn't Hollywood's next big thing, it was obliterated Sunday night. The star and creator of HBO's "Girls" went home with two awards, best actress in a TV comedy and best TV comedy. Her heartfelt acceptance speech for best actress struck a chord: "This award is for everyone who feels like there wasn't a place for her," she said. "This show made a space for me."

Jessica Chastain won the Globe for best actress in a drama for "Zero Dark Thirty." She offered a moving tribute to director Kathryn Bigelow, the first woman to win a best director Oscar who failed to get a nomination for that award this year, though "ZDT" was up for a slew of other awards, including best picture. "I can't help but compare my character of Maya to you," Chastain said to Bigelow. "When you make a film that allows your character to disobey the conventions of Hollywood, you've done more for women in cinema than you take credit for."

Blame it on nerves, the spirit of spontaneity, or the a-a-a-a-alcohol (apologies to Jamie Foxx), but Jennifer Lawrence's acceptance speech was a tad insulting to a Hollywood icon, if totally hilarious. "Oh what does it say?" she asked, looking at her trophy. "I beat Meryl." She meant Meryl Streep, who was also up for the award.

Syria war envelops region in "staggering" crisis: aid agency

BEIRUT (Reuters) - Syria's civil war is unleashing a "staggering humanitarian crisis" on the Middle East as hundreds of thousands of refugees flee violence including gang rape, an international aid agency said on Monday.

Opposition activists said an air strike on rebel-held territory southwest of Damascus killed 20 people, including women and children, adding to the more than 60,000 people estimated to have been killed in the 21-month-old conflict.

Over 600,000 Syrians have fled abroad - many to neighboring Turkey, Lebanon and Jordan - as violence has spread and international efforts to find a political solution have sagged.

Refugees interviewed by the International Rescue Committee (IRC) cited sexual violence as a major reason they fled the country, the New York-based organization said in a 23-page report on the crisis published on Monday.

Gang rapes often happened in front of family members and women had been kidnapped, raped, tortured and killed, it said.

"After decades of working in war and disaster zones, the IRC knows that women and girls suffer physical and sexual violence in every conflict. Syria is no exception," the group added.

Rebels and government forces have both been accused of human rights abuses during the conflict, which began with peaceful protests against President Bashar al-Assad in March 2011.

The unrest turned violent after government forces fired on demonstrators and has since become a full-scale civil war.

Fierce winter weather has worsened the plight of hundreds of thousands of refugees. The IRC urged donors to step up planning and funding in the expectation that more Syrians will flee.

"Nearly two years into Syria's civil war, the region faces a staggering humanitarian disaster," the IRC report said.

AIR POWER

Despite advancing in Syria's north and east and winning support from regional powers like Turkey and Saudi Arabia, the Syrian rebels have been unable to break a military stalemate with government forces elsewhere.

They have struggled to counter government air power in particular, making it hard for them to take and hold territory crucial to Assad's grip on power, including major cities.

An activist in Moadamiyeh, a rebel-held town southwest of Damascus, said an air strike there killed 20 people on Monday.

Activist video footage showed images of the limp body of a boy being pulled out from broken concrete, his back covered in dust and his front in blood.

The Syrian Observatory for Human Rights, a Britain-based monitoring group, said at least 13 people had died in the air raid but the toll was likely to rise.

Syrian state television said "terrorists" - its word for rebels - had fired a mortar from the Damascus suburb of Daraya on a civilian building in Moadamiyeh, killing women and children.

The reports could not be independently verified because of government restrictions on independent media in Syria.

Syrian warplanes also bombarded the strategic Taftanaz air base that rebels seized last week, the Observatory said.

In another sign of escalating bloodshed, Human Rights Watch said it had evidence that government forces had used multi-barrel rocket launchers to deliver Egyptian-made cluster munitions in recent attacks.

"Syria is escalating and expanding its use of cluster munitions, despite international condemnation of its embrace of this banned weapon," it said.

DEADLOCK

Syria's rising death toll has brought international intervention no closer. The United States and Russia have been deadlocked over how to resolve the crisis.

Moscow - which has continued to back its long-standing ally and arms client Assad - urged the opposition on Sunday to make its own proposals in response to a speech by Assad a week ago.

The speech, which offered no concessions, was criticized by the United Nations and United States. Syrian rebels described it as a renewed declaration of war.

Talks between Russia and the United States in Geneva on Friday failed to produce a breakthrough.

As diplomatic efforts have stalled, the conflict has continued to draw in Syria's neighbors.

A mortar round apparently fired from Syria crashed in a field in Turkey overnight close to a refugee camp housing thousands of Syrians along the border, Turkish state media said.

NATO troops have begun deploying Patriot defense missiles in Turkey against a potential attack from its southern neighbor. The missiles are expected to be operational by the end of the month. Turkey is a strong supporter of the Syrian rebels.

NATO said Syrian government forces had launched a short-range, Scud-style ballistic missile on Sunday, bringing to more than 20 the number launched in the past month.

The missiles, apparently fired against opposition targets, landed in Syrian territory, mostly in northern Syria, a NATO spokeswoman said in Brussels, but some of the missiles landed "quite close" to the Turkish frontier.

S'pore's productivity well below most developed countries: DPM Tharman

SINGAPORE: Singapore's productivity is well below that of the most developed countries, according to Deputy Prime Minister and Finance Minister Tharman Shanmugaratnam.

In a Facebook post on Sunday, he noted that restaurants here are experiencing difficulties finding employees.

Mr Tharman said some restaurants have raised pay to attract part-timers during the peak Lunar New Year season.

But most still have difficulty finding people, because the overall labour market is close to full employment.

DPM Tharman said these are real problems for businesses, but the solution is not to ease up on foreign worker policies.

He said the solution has to be more fundamental.

Using restaurants in the US, Europe, Japan, and Hong Kong as examples, he noted that they have fewer workers, but are still able to do well.

The same employee handles more duties, and serves more tables.

The employees are well-paid, both full-time and part-time.

They know their stuff, including details of the dishes on the menu, and are well trained.

The restaurants also employ older workers, give them good jobs with some adjustments where required, and customers treat them with respect.

Mr Tharman said productivity then becomes key to upgrading incomes and standards of living - and transforming jobs is the only 'fundamental and sustainable' solution.

Higher productivity will also mean price increments can be minimised - even if wages go up.

He said everyone has to play his or her part.

Employers have to transform the way businesses are run and share productivity gains with their employees through higher pay.

Employees need to pick up skills and keep learning on the job.

Mr Tharman said the government has to keep the foreign worker policy tight, but at the same time lend strong support to help this upgrading and upskilling in every sector.

And customers too have to play their part by treating workers in ordinary jobs with respect.

JSTOR says it mourns `tragic loss' of Aaron Swartz

As the Internet exploded with anger over news that online activist Aaron Swartz had committed suicide on Friday, the subscription-only archive he was accused of hacking said late today that it "regretted" having been drawn to "this sad event."

Swartz, a celebrated computer activist and programming prodigy, was fighting two-year-old charges that he stole 4 million documents from the Massachusetts Institute of Technology and JSTOR, or Journal Storage, an archive of scientific journals and academic papers. If convicted, Swartz faced a maximum of $4 million in fines and more than 50 years in prison after the government increased the number of felony counts against Swartz to 13 from 4.

Federal authorities alleged that Swartz broke into computer networks at M.I.T. to illegally gain access to JSTOR's archive. But critics of the government said the Feds were unfairly trying to make an example out of Swartz. In a post today Prosecutor as bully legal scholar Larry Lessig wrote that "the government worked as hard as it could to characterize what Aaron did in the most extreme and absurd way."

Here is the text of the JSTOR release:

We are deeply saddened to hear the news about Aaron Swartz. We extend our heartfelt condolences to Aaron's family, friends, and everyone who loved, knew, and admired him. He was a truly gifted person who made important contributions to the development of the internet and the web from which we all benefit.

We have had inquiries about JSTOR's view of this sad event given the charges against Aaron and the trial scheduled for April. The case is one that we ourselves had regretted being drawn into from the outset, since JSTOR's mission is to foster widespread access to the world's body of scholarly knowledge. At the same time, as one of the largest archives of scholarly literature in the world, we must be careful stewards of the information entrusted to use by the owners and creators of that content. To that end.

Aaron returned the data he had in his possession and JSTOR settled any civil claims we might have had against him in June 2011. JSTOR is a not-for-profit service and a member of the internet community.l We will continue to work to distribute the content under our care as widely as possible while balancing the interests of researchers, students, libraries, and publishers as we pursue our commitment to the long-term preservation of this important scholarly literature. We join those who are mourning this tragic loss.

Beijing air pollution off the charts

BEIJING People refused to venture outdoors and buildings disappeared into Beijing's murky skyline on Sunday as the air quality in China's notoriously polluted capital went off the index.

The Beijing Municipal Environmental Monitoring Center said on its website that the density of PM2.5 particulates had surpassed 700 micrograms per cubic meter in many parts of the city. The World Health Organization considers a safe daily level to be 25 micrograms per cubic meter.

PM2.5 are tiny particulate matter less than 2.5 micrometers in size, or about 1/30th the average width of a human hair. They can penetrate deep into the lungs, so measuring them is considered a more accurate reflection of air quality than other methods.

The Beijing center recommended that children and the elderly stay indoors, and that others avoid outdoor activities.

The U.S. Embassy also publishes data for PM2.5 on Twitter, and interprets the data according to more stringent standards.

In the 24-hour period up to 10 a.m. Sunday, it said 18 of the hourly readings were "beyond index." The highest number was 755, which corresponded to a PM2.5 density of 886 micrograms per cubic meter. The U.S. Environmental Protection Agency's air quality index goes up to only 500, and the agency advises that anything greater than 300 would trigger a health warning of "emergency conditions," with the entire population likely affected.

While some people vowed to stay indoors with air purifiers turned on, Beijing's streets were still fairly busy Sunday, and there was the familiar sight of heavy traffic on main thoroughfares.

A young couple strolled along hand in hand in the central business district, both with matching white masks strung around their faces. Two Taiwanese tourists wore masks they said they had brought with them because they heard Beijing's pollution was so bad.

"I don't know why there is such heavy haze these past days. It's really quite serious compared with the air quality three days ago," said a 33-year-old lawyer, who would give only his surname, Liu, as he adjusted his own mask. He said he had ventured out only because he needed to go shopping.

Beijing's air started to worsen on Thursday. The Beijing monitoring center has said the pollution is expected to linger until Tuesday.

Poisoned Lottery Winner's Kin Were Suspicious

Urooj Khan had just brought home his $425,000 lottery check when he unexpectedly died the following day. Now, certain members of Khan's family are speaking publicly about the mystery -- and his nephew told ABC News they knew something was not right.

"He was a healthy guy, you know?" said the nephew, Minhaj Khan. "He worked so hard. He was always going about his business and, the thing is: After he won the lottery and the next day later he passes away -- it's awkward. It raises some eyebrows."

The medical examiner initially ruled Urooj Khan, 46, an immigrant from India who owned dry-cleaning businesses in Chicago, died July 20, 2012, of natural causes. But after a family member demanded more tests, authorities in November found a lethal amount of cyanide in his blood, turning the case into a homicide investigation.

"When we found out there was cyanide in his blood after the extensive toxicology reports, we had to believe that ... somebody had to kill him," Minhaj Khan said. "It had to happen, because where can you get cyanide?"

Authorities could be one step closer to learning what happened to Urooj Khan. A judge Friday approved an order to exhume his body at Rosehill Cemetery in Chicago as early as Thursday to perform further tests.

Lottery Winner Murdered: Widow Questioned By Police Watch Video

Moments after the court hearing, Urooj Khan's sister, Meraj Khan, remembered her brother as the kind of person who would've shared his jackpot with anyone. Speaking at the Cook County Courthouse, she hoped the exhumation would help the investigation.

"It's very hard because I wanted my brother to rest in peace, but then we have to have justice served," she said, according to ABC News station WLS in Chicago. "So if that's what it takes for him to bring justice and peace, then that's what needs to be done."

Khan reportedly did not have a will. With the investigation moving forward, his family is waging a legal fight against his widow, Shabana Ansari, 32, over more than $1 million, including Urooj Khan's lottery winnings, as well as his business and real estate holdings.

Khan's brother filed a petition Wednesday to a judge asking Citibank to release information about Khan's assets to "ultimately ensure" that [Khan's] minor daughter from a prior marriage "receives her proper share."

Ansari may have tried to cash the jackpot check after Khan's death, according to court documents, which also showed Urooj Khan's family is questioning if the couple was ever even legally married.

Ansari, Urooj Khan's second wife, who still works at the couple's dry cleaning business, has insisted they were married legally.

She has told reporters the night before her husband died, she cooked a traditional Indian meal for him and their family, including Khan's daughter and Ansari's father. Not feeling well, Khan retired early, Ansari told the Chicago Sun-Times, falling asleep in a chair, waking up in agony, then collapsing in the middle of the night. She said she called 911.

"It has been an incredibly hard time," she told ABC News earlier this week. "We went from being the happiest the day we got the check. It was the best sleep I've had. And then the next day, everything was gone.

"I am cooperating with the investigation," Ansari told ABC News. "I want the truth to come out."

Ansari has not been named a suspect, but her attorney, Steven Kozicki, said investigators did question her for more than four hours.

France bombs Mali rebels as more troops arrive in Bamako

BAMAKO/PARIS (Reuters) - French fighter jets bombed Islamist rebels in Mali for a third day on Sunday as Paris poured more troops into the capital Bamako, awaiting the arrival of a West African force to dislodge al Qaeda-linked insurgents from the country's north.

French Defence Minister Jean-Yves Le Drian said France's dramatic intervention on Friday to bomb a convoy of heavily armed Islamist fighters sweeping southwards had stopped them from seizing Mali's capital Bamako within days.

Western countries fear Islamists could use Mali as a base for attacks on the West, forming a link with al Qaeda militants in Yemen, Somalia and North Africa.

Le Drian said former colonial power France was carrying out continuous bombing raids against the alliance of rebel groups, which seized the country's vast desert north in April.

"There are raids going on now: there were some last night, and there will be more tomorrow," Le Drian told French television. "The president is totally determined that we must eradicate these terrorists who threaten the security of Mali, our own country and Europe."

Residents said French aircraft bombed the northern town of Gao, and a Malian rebel spokesman said they bombed targets in the towns of Lere and Douentza.

Le Drian said France was deploying a further contingent of 80 soldiers to Mali on Sunday, bring the total to 550 soldiers , split between Bamako and the town of Mopti, some 500 km (300 miles) north. State-of-the-art Rafale fighter jets would be dispatched to reinforce the operation on Sunday, he said.

A Reuters cameraman reported seeing on Sunday more than 100 French troops disembarking from a military cargo plane at Bamako airport, just on the outskirts of the capital.

Bamako itself was calm on Sunday, with the sun streaking through the dust enveloping the city as the seasonal Harmattan wind blew from the Sahara. Some cars drove around with French flags draped from the windows to celebrate Paris's intervention.

Hours after opening one front against al Qaeda-linked Islamists, France mounted a commando raid to free a French hostage in Somalia held by al Shabaab militants allied to al Qaeda, but failed to stop him being killed along with a French commando.

A French pilot was killed on Friday when rebels in Mali shot down his helicopter.

President Francois Hollande has made it clear that France's aim in Mali is to support the deployment of a West African mission to retake the north, endorsed by the United Nations, the European Union and the United States.

The 15-nation West African bloc ECOWAS convened a summit for Saturday in Ivory Coast to discuss the military campaign.

With Paris pressing West African nations to deploy troops quickly, Ivory Coast President Alassane Ouattara, who holds the rotating ECOWAS chairmanship, has kick-started the operation to deploy some 3,300 African soldiers.

Ouattara was himself installed in power with French military backing in 2011 after a brief civil war triggered by former president Laurent Gbagbo's refusal to step aside after losing a late 2010 election.

"The troops will start arriving in Bamako today and tomorrow," Ali Coulibaly, Ivory Coast's African Integration Minister, said. "They will be convoyed to the front at Sevare."

HOUSE-TO-HOUSE SEARCHES

Under cover from French fighter planes and attack helicopters on Friday, Malian troops drove the Islamists out of the strategic central town of Konna, which they had seized a day earlier. A senior Malian army official said more than 100 rebel fighters had been killed.

Military analysts expressed doubt, however, that this was the start of a swift operation to retake the whole of northern Mali - a harsh, sparsely populated terrain the size of France - as neither equipment nor ground troops were ready.

In Nigeria, which will lead the ECOWAS force, a military official who asked not to be identified said it would take time to train and equip the troops.

In Konna, calm returned after three nights of combat.

"Soldiers are patrolling the streets and have encircled the town," one resident, Madame Coulibaly, told Reuters by phone. "They are searching houses for arms or hidden Islamists."

Another inhabitant said the army set up roadblocks along the route north from Sevare to Konna and was checking for rebels. President Diouncounda Traore declared a state of emergency on Friday giving the military sweeping powers to carry out searches and shut down parts of the country.

"The army is in Konna ... securing the town and to make sure it is safe," army spokesman Lieutenant Colonel Diarran Kone said.

A resident in the northern city of Gao, one of the Islamists' strongholds, had reported scores of rebel fighters were retreating northward in pickup trucks on Saturday. In Bamako, some civilians tried to contribute to the war effort.

"We are very proud and relieved that the army was able to drive the jihadists out of Konna. We hope it will not end there that is why I'm helping in my own way," said civil servant Ibrahima Kalossi, 32, one of over 40 people who queued to donate blood for wounded soldiers.

Concerned about reprisals on French soil, Hollande instructed Prime Minister Jean-Marc Ayrault to tighten security in France at public buildings and on public transport.

France advised its 6,000 citizens in Mali to leave. Thousands more French live across West Africa, particularly in Senegal and Ivory Coast.

Hollande's intervention in Mali could endanger eight French nationals being held by Islamists in the Sahara. A spokesman for one of Mali's rebel groups, Ansar Dine, said on Saturday there would be repercussions.

"There are consequences, not only for French hostages, but also for all French citizens, wherever they find themselves in the Muslim world," Sanda Ould Boumama told Reuters. "The hostages are facing death."
