25 top-rated Facebook games from 2012

Games can be both a welcome and an annoying diversion on Facebook, the world’s most popular online social network. This year, Facebook crossed a big milestone — reaching 1 billion active users. Game companies such as “FarmVille” creator Zynga Inc. and Rovio Entertainment Ltd. of “Angry Birds” fame seek to tap into that vast base of users to gain more players for their games.

This week, Facebook Inc. issued a list of the 25 top-rated games that launched on Facebook in 2012. The company says the rankings are based on user ratings and engagement with the games. It’s the same methodology that Facebook uses to rank apps in its App Center.

Some of the games are played on Facebook’s website, while others are only on Apple Inc.‘s iOS or Google Inc.‘s Android devices using Facebook’s app.

Longer tamoxifen use cuts breast cancer deaths

Breast cancer patients taking the drug tamoxifen can cut their chances of having the disease come back or kill them if they stay on the pills for 10 years instead of five years as doctors recommend now, a major study finds.

The results could change treatment, especially for younger women. The findings are a surprise because earlier research suggested that taking the hormone-blocking drug for longer than five years didn't help and might even be harmful.

In the new study, researchers found that women who took tamoxifen for 10 years lowered their risk of a recurrence by 25 percent and of dying of breast cancer by 29 percent compared to those who took the pills for just five years.

In absolute terms, continuing on tamoxifen kept three additional women out of every 100 from dying of breast cancer within five to 14 years from when their disease was diagnosed. When added to the benefit from the first five years of use, a decade of tamoxifen can cut breast cancer mortality in half during the second decade after diagnosis, researchers estimate.

Some women balk at taking a preventive drug for so long, but for those at high risk of a recurrence, "this will be a convincer that they should continue," said Dr. Peter Ravdin, director of the breast cancer program at the UT Health Science Center in San Antonio.

He reviewed results of the study, which was being presented Wednesday at a breast cancer conference in San Antonio and published by the British medical journal Lancet.

"The result of this trial will have a major, immediate impact on premenopausal women," Ravdin said.

About 50,000 of the roughly 230,000 new cases of breast cancer in the United States each year occur in women before menopause. Most breast cancers are fueled by estrogen, and hormone blockers are known to cut the risk of recurrence in such cases.

Tamoxifen long was the top choice, but newer drugs called aromatase inhibitors — sold as Arimidex, Femara, Aromasin and in generic form — do the job with less risk of causing uterine cancer and other problems.

But the newer drugs don't work well before menopause. Even some women past menopause choose tamoxifen over the newer drugs, which cost more and have different side effects such as joint pain, bone loss and sexual problems.

The new study aimed to see whether over a very long time, longer treatment with tamoxifen could help.

Dr. Christina Davies of the University of Oxford in England and other researchers assigned 6,846 women who already had taken tamoxifen for five years to either stay on it or take dummy pills for another five years.

Researchers saw little difference in the groups five to nine years after diagnosis. But beyond that time, 15 percent of women who had stopped taking tamoxifen after five years had died of breast cancer versus 12 percent of those who took it for 10 years. Cancer had returned in 25 percent of women on the shorter treatment versus 21 percent of those treated longer.

Tamoxifen had some troubling side effects: Longer use nearly doubled the risk of endometrial cancer. But it rarely proved fatal, and there was no increased risk among premenopausal women in the study — the very group tamoxifen helps most.

"Overall the benefits of extended tamoxifen seemed to outweigh the risks substantially," Dr. Trevor Powles of the Cancer Centre London wrote in an editorial published with the study.

The study was sponsored by cancer research organizations in Britain and Europe, the United States Army, and AstraZeneca PLC, which makes Nolvadex, a brand of tamoxifen, which also is sold as a generic for 10 to 50 cents a day. Brand-name versions of the newer hormone blockers, aromatase inhibitors, are $300 or more per month, but generics are available for much less.

The results pose a quandary for breast cancer patients past menopause and those who become menopausal because of their treatment — the vast majority of cases. Previous studies found that starting on one of the newer hormone blockers led to fewer relapses than initial treatment with tamoxifen did.

Another study found that switching to one of the new drugs after five years of tamoxifen cut the risk of breast cancer recurrence nearly in half — more than what was seen in the new study of 10 years of tamoxifen.

"For postmenopausal women, the data still remain much stronger at this point for a switch to an aromatase inhibitor," said that study's leader, Dr. Paul Goss of Massachusetts General Hospital. He has been a paid speaker for a company that makes one of those drugs.

Women in his study have not been followed long enough to see whether switching cuts deaths from breast cancer, as 10 years of tamoxifen did. Results are expected in about a year.

The cancer conference is sponsored by the American Association for Cancer Research, Baylor College of Medicine and the UT Health Science Center.

Dow, S&P end higher, but Apple sinks Nasdaq in wild day

NEW YORK (Reuters) - A volatile trading session ended with stocks mostly higher on Wednesday, even as Apple, the most valuable company in the United States, suffered its worst day of losses in almost four years.

In a strange occurrence, Apple accounted for the entirety of the Nasdaq 100's <.ndx> fall of 1.1 percent, while the Dow industrials - which do not include Apple as a component - enjoyed the best day since November 28.

With the drop, Apple shed nearly $35 billion in market capitalization, its biggest one-day market-cap loss ever. The company's market value, or market capitalization, now stands at $506.85 billion.

"Today's move is because of index weightings, with the Nasdaq down because of Apple's decline," said Rex Macey, chief investment officer of Wilmington Trust in Atlanta. "The S&P is up because Apple isn't as big a weight in that index, and the Dow is up even more because it isn't there at all."

The broad market seesawed, with the S&P 500 dropping into negative territory before it rebounded off the 1,400 level, seen as a key support point over the past two weeks. Investors cited comments from President Barack Obama suggesting a potential near-term resolution to the "fiscal cliff" wrangling in Washington as a catalyst for the rebound.

Shares of The Travelers Cos Inc rose 4.9 percent to $74. The stock ranked as the Dow's top percentage gainer after the insurance company said it intended to resume stock buybacks it had temporarily suspended while it assessed its exposure to Superstorm Sandy. The company also said a preliminary estimate of net losses from Sandy was about $650 million after tax.

The Dow Jones industrial average <.dji> rose 82.71 points, or 0.64 percent, to 13,034.49 at the close. The Standard & Poor's 500 Index <.spx> gained 2.23 points, or 0.16 percent, to 1,409.28. But the Nasdaq Composite Index <.ixic> fell 22.99 points, or 0.77 percent, to end at 2,973.70.

Apple, the largest U.S. company by market capitalization and a big weight in both the S&P 500 and the Nasdaq, fell 6.4 percent to $538.79. Apple is down more than 20 percent from an all-time high reached in late September, putting the stock into bear market territory.

Banking shares were led higher by a 6.3 percent jump in Citigroup to $36.46 after the company said it would cut 4 percent of its workforce. [ID:nL1E8N52IQ] The S&P financial sector index <.gspf> climbed 1.3 percent, and Bank of America hit a 52-week high of $10.55 before pulling back slightly. The stock, a Dow component, ended at $10.46, up 5.7 percent for the day.

Still, Apple struggled throughout the session. Market participants cited a host of reasons for the drop in the iPad maker's stock, including a consultant's report about the company losing share in the tablet market and reports that margin requirements had been raised by at least one clearing firm, as well as year-end tax selling ahead of a possible rise in capital-gains tax rates next year.

On the Washington front, Obama told the Business Roundtable, a group of chief executives, on Wednesday that a fiscal cliff deal was possible "in about a week" if Republicans acknowledged the need to raise taxes on the wealthiest Americans.

Equities have struggled to gain ground recently because of concerns over the fiscal cliff - a series of mandatory spending cuts and tax increases effective in early January that could push the U.S. economy into recession next year. Recently equities have moved on any whiffs of sentiment from Washington in headlines about negotiations.

"Obama's comments generated a lot of optimism, but to the extent the market believes them, that's how much we're setting ourselves up for a decline if that deadline passes with no progress," said Macey, who helps oversee about $20 billion in assets.

In an interview on CNBC after the market closed, U.S. Treasury Secretary Tim Geithner said that uncertainty over the fiscal cliff was standing in the way of stronger economic growth, and that there was no prospect for an agreement if tax rates didn't rise on the wealthiest taxpayers.

The stock of Freeport-McMoRan Copper & Gold Inc fell 16 percent to $32.17 and ranked as the S&P 500's biggest percentage decliner. The company said it was acquiring Plains Exploration & Production Co and McMoRan Exploration Co in two separate deals for $9 billion in cash and stock in a major expansion into energy.

McMoRan Exploration soared 87 percent to $15.82 and Plains surged 23.4 percent to $44.50.

After the closing bell, Standard & Poor's said it cut Greece's sovereign long-term foreign currency rating to "selective default" from its already low "C" rating. Last week, the country and its international lenders reached a deal to lower its debt burden through a debt buyback.

About half of the stocks traded on the New York Stock Exchange closed in positive territory, while about 54 percent of Nasdaq-listed shares ended lower.

Volume was higher than it has been in recent sessions, with about 7.01 billion shares changing hands on the New York Stock Exchange, the Nasdaq and NYSE MKT, above the daily average so far this year of about 6.48 billion shares.

Clashes erupt in Egypt despite proposal to end crisis

CAIRO (Reuters) - Islamists fought protesters outside the Egyptian president's palace on Wednesday, while inside the building his deputy proposed a way to end a crisis over a draft constitution that has split the most populous Arab nation.

Stones and petrol bombs flew between opposition protesters and supporters of President Mohamed Mursi, and the Interior Ministry said 32 people had been arrested and three police vehicles destroyed.

Two Islamists were hit in the legs by what their friends said were bullets fired during clashes in streets around the compound in northern Cairo. One of them was bleeding heavily. And a leftist group said Islamists had cut off the ear of one of its members.

Medical sources said 33 people had been wounded, but despite reports of fatalities, the Health Ministry said there had been no deaths.

Riot police were deployed between the two sides in Cairo to try to stop confrontations that flared after dark despite an attempt by Vice President Mahmoud Mekky to ease the crisis.

Mekky said amendments to disputed articles in the draft constitution could be agreed with the opposition. A written agreement could then be submitted to the next parliament, to be elected after a referendum on the constitution on December 15.

"There must be consensus," he told a news conference, saying opposition demands had to be respected to reach a solution.

Prime Minister Hisham Kandil called for calm to "give the opportunity" for efforts underway to start a national dialogue.

Facing the gravest crisis of his six-month-old tenure, Mursi has shown no sign of buckling to the protests, confident that Islamists can win the referendum and a parliamentary election to follow.

Many Egyptians yearn for an end to political upheaval that began with the overthrow of Hosni Mubarak in February 2011 and which has hurt the economy as investors and tourists have fled.

Protests spread to other cities, and offices of the Brotherhood's political party in Ismailia and Suez were torched.

Egypt's opposition coalition blamed Mursi for the violence and said it was ready for dialogue if the Islamist leader scrapped a decree he issued on November 22 that gave him wide powers and shielded his decisions from judicial review.

DIALOGUE

"We hold President Mursi and his government completely responsible for the violence happening in Egypt today," opposition coordinator Mohamed ElBaradei told a news conference.

"We are ready for dialogue if the constitutional decree is cancelled ... and the referendum on this constitution is postponed," he said of the document written by an Islamist-led assembly that the opposition says ignores its concerns.

But liberals, leftists, Christians, ex-Mubarak followers and others opposed to Mursi have yet to generate a mass movement or a grassroots base to challenge the Brotherhood, which has come out on top in two elections since Mubarak's overthrow.

"Today what is happening in the Egyptian street, polarisation and division, is something that could and is actually drawing us to violence and could draw us to something worse," said ElBaradei, the former head of the U.N. nuclear watchdog.

Opposition leaders have previously urged Mursi to retract the November 22 decree, defer the referendum and agree to revise the constitution, but have not echoed calls from street protesters for his overthrow and the "downfall of the regime".

Mursi has said his decree was needed to prevent courts still full of judges appointed by ousted strongman Hosni Mubarak from derailing a constitution vital for Egypt's political transition.

Earlier on Wednesday Islamist supporters of Mursi tore down tents erected outside the presidential palace by leftist foes who had begun a sit-in there.

"They hit us and destroyed our tents. Are you happy, Mursi? Aren't we Egyptians too?" asked protester Haitham Ahmed.

Mohamed Mohy, a pro-Mursi demonstrator who was filming the scene, said: "We are here to support our president and his decisions and save our country from traitors and agents."

Mekky said street mobilisation by both sides posed a "real danger" to Egypt. "If we do not put a stop to this phenomenon right away ... where are we headed? We must calm down."

CALLS FOR RESTRAINT

U.S. Secretary of State Hillary Clinton weighed into Egypt's political debate, saying dialogue was urgently needed on the new constitution, which should "respect the rights of all citizens".

Clinton and Mursi worked together last month to broker a truce between Israel and Hamas Islamists in the Gaza Strip.

Washington is worried about rising Islamist power in Egypt, a staunch U.S. security partner under Mubarak, who preserved the U.S.-brokered peace treaty Cairo signed with Israel in 1979.

British Foreign Secretary William Hague called for restraint on all sides. He said Egypt's authorities had to make progress on the transition in an "inclusive manner" and urged dialogue.

The Muslim Brotherhood had summoned supporters to an open-ended demonstration at the presidential palace, a day after about 10,000 opposition protesters had encircled it for what organizers dubbed a "last warning" to Mursi.

State institutions, with the partial exception of the judiciary, have mostly fallen in behind Mursi.

The army, the muscle behind all previous Egyptian presidents in the republic's six-decade history, has gone back to barracks, having apparently lost its appetite to intervene in politics.

In August Mursi sacked Mubarak-era army commander and defense minister Mohamed Hussein Tantawi and removed the sweeping powers that the military council, which took over after Mubarak fell, had grabbed two months earlier.

Investors have seized on hopes that Egypt's turbulent transition, which has buffeted the economy for two years, may soon head for calmer waters, sending stocks 1.6 percent higher after a 3.5 percent rally on Tuesday.

Egypt has turned to the IMF for a $4.8 billion loan after the depletion of its foreign currency reserves. The government said on Wednesday the process was on track and its request would go to the IMF board as expected.

The board is due to review the facility on December 19.

Elijah Zarwan, a fellow with the European Council on Foreign Relations, said that if Egypt was to find a compromise solution to its crisis, it would not be through slogans and blows.

"It will be through quiet negotiation, not through dueling press conferences, street brawls, or civil strife," he said.

We also spoke with Adriana's trainer, former professional boxer Michael Olajide, who co-founded the AeroSpace fitness studio in New York where she and other celebrities work out. Michael said his unconventional approach to exercise can produce the perfect all-round results for his clients.

"A lot of other exercises, especially cardio exercises, teach you how to run, dance and cycle, so you're using your legs. With aero boxing, you're using your core and your arms," said Michael. "So you're using your upper body to get a great cardio workout, but you also get the great abs, and the beautiful arms, and everything else to go with it."

Adriana said her trainer has been a great motivator. "You need to sacrifice to get the best results and I always got the greatest results with him." For his part, Michael said Adriana's commitment makes his job a lot easier. "Adriana has the mind of a fighter. She's extremely competitive, she always likes to be at the best of her game. So I don't feel that it's a challenge for me at all. I put the challenge out there and she always accepts it."

CDC says US flu season starts early, could be bad

NEW YORK (AP) — Flu season in the U.S. is off to its earliest start in nearly a decade — and it could be a bad one.

Health officials on Monday said suspected flu cases have jumped in five Southern states, and the primary strain circulating tends to make people sicker than other types. It is particularly hard on the elderly.

"It looks like it's shaping up to be a bad flu season, but only time will tell," said Dr. Thomas Frieden, director of the Centers for Disease Control and Prevention.

The good news is that the nation seems fairly well prepared, Frieden said. More than a third of Americans have been vaccinated, and the vaccine formulated for this year is well-matched to the strains of the virus seen so far, CDC officials said.

Higher-than-normal reports of flu have come in from Alabama, Louisiana, Mississippi, Tennessee and Texas. An uptick like this usually doesn't happen until after Christmas. Flu-related hospitalizations are also rising earlier than usual, and there have already been two deaths in children.

Hospitals and urgent care centers in northern Alabama have been bustling. "Fortunately, the cases have been relatively mild," said Dr. Henry Wang, an emergency medicine physician at the University of Alabama at Birmingham.

Parts of Georgia have seen a boom in traffic, too. It's not clear why the flu is showing up so early, or how long it will stay.

"My advice is: Get the vaccine now," said Dr. James Steinberg, an Emory University infectious diseases specialist in Atlanta.

The last time a conventional flu season started this early was the winter of 2003-04, which proved to be one of the most lethal seasons in the past 35 years, with more than 48,000 deaths. The dominant type of flu back then was the same one seen this year.

One key difference between then and now: In 2003-04, the vaccine was poorly matched to the predominant flu strain. Also, there's more vaccine now, and vaccination rates have risen for the general public and for key groups such as pregnant women and health care workers.

An estimated 112 million Americans have been vaccinated so far, the CDC said. Flu vaccinations are recommended for everyone 6 months or older.

On average, about 24,000 Americans die each flu season, according to the CDC.

Flu usually peaks in midwinter. Symptoms can include fever, cough, runny nose, head and body aches and fatigue. Some people also suffer vomiting and diarrhea, and some develop pneumonia or other severe complications.

A strain of swine flu that hit in 2009 caused a wave of cases in the spring and then again in the early fall. But that was considered a unique type of flu, distinct from the conventional strains that circulate every year.

Wall Street dips as investors seek cliff progress

NEW YORK (Reuters) - Stocks finished slightly lower in a quiet session on Tuesday as the back-and-forth wrangling over the "fiscal cliff" gave investors little reason to act.

Trading volume was light as legislators continue to negotiate a deal to avoid a $600 billion package of tax hikes and federal spending cuts that would begin January 1 and could push the economy into recession.

Just 5.86 billion shares changed hands on the New York Stock Exchange, the Nasdaq and the NYSE MKT, below the year's daily average of 6.48 billion shares.

A key measure of investor anxiety has remained muted. The CBOE Volatility Index or VIX <.vix>, a gauge of market anxiety, was at 17.13, up 2.9 percent. It has not traded above 20 since July.

Optimism for progress was dented after remarks by President Barack Obama, who rejected a Republican proposal to resolve the crisis as "out of balance" and said any deal must include a rise in income tax rates on the wealthiest Americans.

"People don't know if what's going on is political posturing or real negotiations that represent progress," said Bernard Baumohl, managing director and chief global economist at the Economic Outlook Group in Princeton, New Jersey.

Expectations of higher taxes on dividends beginning in 2013 have pushed many companies to pay special dividends this year or advance their next payback to investors. Coach became the latest to move up the date of its next dividend payment, and the news lifted shares of the upscale leather-goods maker earlier in the session. By the close, though, Coach was down 1.2 percent at $57.52.

One of the S&P 500's top sectors for the day was health care <.gspa>, considered a defensive group.

The Dow Jones industrial average <.dji> fell 13.82 points, or 0.11 percent, to 12,951.78 at the close. The Standard & Poor's 500 Index <.spx> dipped 2.41 points, or 0.17 percent, to 1,407.05. The Nasdaq Composite Index <.ixic> shed 5.51 points, or 0.18 percent, to close at 2,996.69.

The market has been sensitive to rhetoric from Washington, as a failure to reach an agreement could send the U.S. economy back into recession. Still, many expect a resolution to be found, which could extend the S&P 500's rally of 12 percent so far this year.

Differences within the Republican Party came to the fore on Tuesday as one senator opposed to raising taxes lashed out at Republican House Speaker John Boehner for proposing to increase revenue by closing some tax loopholes.

Congressional Republicans recently proposed steep spending cuts to bring down the budget deficit, but gave no ground on Obama's call to raise tax rates on the rich. The proposal was quickly dismissed by the White House.

"We're on hold trying to figure it out, but investors are stressed since they have to make decisions soon about how to proceed with their investments if taxes are indeed going up. We could see a real pick-up in volume over the next week or so," Baumohl said.

Netflix Inc was the S&P 500's top percentage gainer, advancing 14 percent to $86.65 after Walt Disney Co agreed to give the company exclusive TV distribution rights to its movies, starting in 2016.

Darden Restaurants Inc shares plunged 9.6 percent to $47.40 as the S&P 500's worst performer after the company warned that its latest quarter would miss expectations after unsuccessful promotions led to a decline in sales at its Olive Garden, Red Lobster and LongHorn Steakhouse chains.

In contrast, Big Lots Inc surged 11.5 percent to $31.27 after the close-out retailer posted a smaller-than-expected loss and boosted its full-year adjusted earnings forecast.

MetroPCS Communications shares tumbled 7.5 percent to $9.96 after Sprint Nextel appeared unlikely to make a counter-offer for the wireless service provider.

Almost half of the stocks traded on the New York Stock Exchange closed lower, while 50 percent of Nasdaq-listed shares closed in negative territory.

After the closing bell, Pandora Media Inc

shares plunged 23 percent after the company reported its third-quarter results.

NATO warns Syria not to use chemical weapons

BRUSSELS/BEIRUT (Reuters) - NATO told Syrian President Bashar al-Assad on Tuesday that any use of chemical weapons in his fight against encroaching rebel forces would be met by an immediate international response.

The warning from NATO Secretary-General Anders Fogh Rasmussen came as U.S. government sources said Washington had information that Syria was making what could be seen as preparations to use its chemical arsenal.

Syrian forces meanwhile bombarded rebel districts near Damascus in a sustained counter-attack to stem rebel gains around Assad's power base as the insurgency may be entering a decisive phase.

International concern over Syria's intentions has been heightened by reports that its chemical weapons have been moved and could be prepared for use.

"The possible use of chemical weapons would be completely unacceptable for the whole international community and if anybody resorts to these terrible weapons I would expect an immediate reaction from the international community," Rasmussen told reporters at the start of a meeting of alliance foreign ministers in Brussels.

The chemical threat made it urgent for the alliance to send Patriot anti-missile missiles to Turkey, Rasmussen said.

The French Foreign Ministry referred to "possible movements on military bases storing chemical weapons in Syria" and said the international community would react if they were used.

Britain has told the Syrian government that any use of chemical weapons would have "serious consequences", Foreign Secretary William Hague said.

U.S. President Barack Obama on Monday told Assad not to use chemical weapons, without saying how the United States might respond. The Foreign Ministry in Damascus said it would never use such weapons against Syrians.

CLASSIFIED INTELLIGENCE

The U.S. has collected what has been described as highly classified intelligence information demonstrating that Syria is making what could be construed as preparations to use elements of its extensive chemical weapons arsenal, two U.S. government sources briefed on the issue said.

One of the sources said that there was no question that the US "Intelligence community" had received information pointing to "preparations" under way in Syria related to chemical weapons. The source declined to specify what kind of preparations had been reported, or how close the intelligence indicated the Syrians were to deploying or even using the weapons.

Western military experts say Syria has four suspected chemical weapons sites, and it can produce chemical weapons agents including mustard gas and sarin, and possibly also VX nerve agent. The CIA has estimated that Syria possesses several hundred liters of chemical weapons and produces hundreds of tonnes of agents annually.

The fighting around Damascus has led foreign airlines to suspend flights and prompted the United Nations and European Union to reduce their presence in the capital, adding to a sense that the fight is closing in.

The army fightback came a day after the Syrian foreign ministry spokesman was reported to have defected in a potentially embarrassing blow to the government.

The Syrian Observatory for Human Rights said 200 people were killed across Syria on Monday, more than 60 of them around Damascus. Assad's forces bombarded districts to the south-east of the capital on Tuesday, near to the international airport, and in the rebel bastion of Daraya to the south-west.

Opposition footage posted on the Internet showed a multiple rocket launcher fire 20 rockets, which activists said was filmed at the Mezze military airport in Damascus.

Reuters could not independently verify the footage due to the government's severe reporting restrictions.

In central Damascus, shielded for many months from the full force of a civil war in which 40,000 people have been killed, one resident reported hearing several loud explosions.

"I have heard four or five thunderous blows. It could be barrel bombs," she said, referring to makeshift bombs which activists say Assad's forces have dropped from helicopters on rebel-dominated areas.

MORTAR ATTACK

The state news agency said that 28 students and a teacher were killed near the capital when rebels fired a mortar bomb on a school. Rebels have targeted government-held residential districts of the capital.

The mainly Sunni Muslim rebel forces have made advances in recent weeks, seizing military bases, including some close to Damascus, from forces loyal to Assad, who is from Syria's Alawite minority linked to Shi'ite Islam.

Faced with creeping rebel gains across the north and east of the country, and the growing challenge around the capital, Assad has increasingly resorted to air strikes against the insurgents.

A diplomat in the Middle East said Syrian Foreign Ministry spokesman Jihad Makdissi had left the country and defected, while the British-based Observatory said it had information that he flew from Beirut on Monday afternoon heading for London.

In Beirut, a diplomat said Lebanese officials had confirmed that Makdissi spent several days in Beirut before leaving on Monday, but could not confirm his destination.

"We're aware of reports that he has defected and may be coming to the UK. We're seeking clarification," a Foreign Office spokeswoman in London said.

Makdissi was the public face to the outside world of Assad's government as it battled the 20-month-old uprising. But he had barely appeared in public for several weeks before Monday's report of his defection.

He had little influence in a system largely run by the security apparatus and the military. But Assad's opponents will see the loss of such a high profile figure, if confirmed, as further evidence of a system crumbling from within.

The United Nations and European Union both said they were reducing their presence in Syria in response to the escalated violence around the capital.

A spokesman for U.N. humanitarian operations said the move would not stop aid deliveries to areas which remained accessible to relief convoys.

"U.N.-funded aid supplies delivered through SARC (Syrian Arab Red Crescent) and other charities are still moving daily where the roads are open," Jens Laerke told Reuters in Geneva.

"We have not suspended our operation, we are reducing the non-essential international staff."

Three remaining international staff at the European Union delegation, who stayed on in Damascus after the departure of most Western envoys, crossed the border into Lebanon on Tuesday after pulling out of the Syrian capital.
