SAN FRANCISCO (Reuters) - Getting married was a smart business move as well as a personal milestone for Facebook chief Mark Zuckerberg, with the timing of the wedding, the day after the company's initial public offering, potentially proving particularly advantageous, California divorce lawyers said on Sunday. Assuming the couple signed a prenuptial agreement, as most wealthy Californians do, Zuckerberg and Chan would have agreed exactly how to split assets, including his Facebook stock, if their marriage dissolved in future. ...

He was 62. The singer had colon and liver cancer and, despite brief improvements in his health in recent months, passed away on Sunday evening.

NEW YORK (Reuters) - Blind Chinese activist Chen Guangcheng soaked up the sun in New York City on Sunday as his children played in a garden, a break in a day of meetings to arrange his studies at New York University. "(Chen) said he hadn't sat in the sun for many, many years," said Jerome Cohen, a China law expert and professor at New York University's law school, where Chen will study. "He wanted to go out in the garden... his kids went out first and then he went out," Cohen, who has become a confidante of Chen's, told Reuters. ...

With his carefully tended hair, tight trousers and perfect harmonies, Robin Gibb, along with his brothers Maurice and Barry, defined the disco era. As part of the Bee Gees — short for the Brothers Gibb — they created dance floor classics like "Stayin Alive," ''Jive Talkin'," and "Night Fever" that can still get crowds onto a dance floor.

TOKYO (Reuters) - Markets recovered some ground on Monday after heavy losses last week, but investors remained wary about the euro zone despite world leaders calling for Greece to stay in the monetary union and for Europe to balance austerity with growth. G8 leaders meeting at the weekend vowed to take all necessary steps to combat financial turmoil and revitalize a global economy increasingly threatened by Europe's debt crisis, but they offered no specific prescription for debt-crippled Greece which holds fresh elections next month. ...

Millions of Asians watched as a rare "ring of fire" eclipse crossed their skies early Monday.

A magnitude-6.0 earthquake shook several small towns in northeast Italy, killing four people, knocking down a clock tower and other centuries-old buildings and causing millions in losses to the region known for making Parmesan cheese.

MOSCOW (Reuters) - Russia's deputy foreign minister said on Sunday that military action against Iran over its nuclear program was being considered in some Western countries. Deputy Foreign Minister Sergei Ryabkov was speaking to reporters on a plane on his way back from the G8 summit in Camp David, where the G8 leaders signaled their readiness to tap into emergency oil stockpiles quickly this summer if tougher new sanctions on Iran threatened to strain supplies. ...

(Reuters) - A pledge by leaders of industrialized nations to help the troubled world economy is unlikely to herald quick new action by Europe on its debt crisis, meaning more uncertainty for nervous financial markets. The Group of Eight economies stressed on Saturday that their "imperative is to promote growth and jobs", as they also recognized problems among European banks and gave verbal backing for Greece to stay in the euro. Still, despite U.S. calls for immediate moves to boost growth, no sign emerged that Germany would soften its stance on austerity as the cure for Europe's debt ...

Gunmen fired rocket-propelled grenades and machine guns early Monday in intense street battles in the Lebanese capital, wounding six people as fears mounted that the conflict in neighboring Syria was bleeding across the border.

CHICAGO (Reuters) - NATO leaders charting a path out of Afghanistan sought on Sunday to dispel fears of a rush for the exits in the unpopular war even as France's new president vowed to stick by his pledge to withdraw French troops by year's end. President Barack Obama, who once called the Afghan conflict a "war of necessity" but is now looking for an orderly way out, hosted the NATO summit in his home town, Chicago, a day after major industrialized nations tackled a European debt crisis that threatens the global economy. ...

BELGRADE (Reuters) - Opposition leader Tomislav Nikolic, last in power when Slobodan Milosevic's Serbia was bombed by NATO in 1999, was elected president on Sunday and pledged to keep the former Yugoslav republic moving towards the European Union. In a major upset, rightist Nikolic narrowly defeated liberal leader Boris Tadic, ending his eight years as head of state in a tense run-off election in which fewer than half of Serbia's eligible voters turned out. "There is divine justice," Nikolic told jubilant supporters in the capital, Belgrade. ...

He was the embodiment of one of modern Libya's darkest chapters — a man synonymous with horrifying scenes of wreckage, broken families and a plane that fell out of the sky a generation ago. His name, Abdel Baset al-Megrahi, was little known compared to the single word that his deeds represented: Lockerbie.

SANT' AGOSTINO, Italy (Reuters) - A strong earthquake in northern Italy killed at least six people, injured dozens and damaged historic buildings including a famed mediaeval castle early on Sunday, waking terrified citizens and sending thousands running into the streets. The quake, which the U.S. Geological Survey recorded at magnitude 6.0, struck at 4:04 a.m. (0204 GMT) and was followed by a series of jolting aftershocks. At least two of them reached magnitude 5.1, sowing fresh panic, further damaging already weakened buildings and causing more structures to collapse. ...

Nationalist candidate Tomislav Nikolic won the Serbian presidency on Sunday, a result that adds to the political turmoil in the Balkan country and could slow down its attempts to join the European Union.

CHICAGO (Reuters) - Thousands of protesters carried their anti-war message to world leaders at a NATO summit on a steamy Sunday, in a mostly peaceful march led by a group of Iraq War veterans who symbolically gave back their military medals. During the march, a group of black-clad demonstrators darted toward police lines along the route, and some threw water bottles at officers who pushed back and yelled at them to move along, but there were no major incidents. ...

CHICAGO (Reuters) - New French president Francois Hollande likes to style himself as "Mr. Normal," but his sudden debut on the global stage this week has been anything but. From the Oval Office to a meeting of G8 leaders at the Camp David presidential retreat to the NATO summit in Chicago, Hollande, a life-long party official who has never held a ministerial post, sometimes looked as though he were trying the role of international summiteer on for size. Despite some awkwardness, Hollande appeared to pass his initial diplomatic tests. ...

TRIPOLI (Reuters) - Abdel Basset al-Megrahi, the Libyan convicted of the 1988 bombing of a PanAm flight over Lockerbie, died of cancer on Sunday aged 60, leaving many questions on the attack and its aftermath unanswered. Megrahi, who said he was not responsible for bringing the jumbo jet down on the Scottish town and killing 270 people, was found guilty in 2001 but was freed in 2009 and returned to Libya because he had terminal cancer and was not expected to live long. ...

TANGERANG, Indonesia (Reuters) - There are many ways to describe Indonesia's Aburizal Bakrie: multi-millionaire businessman, global mining tycoon, heavyweight contender for the presidency in 2014. One description that does not spring to mind is man of the common people. So when Bakrie strode into a railway station in south Jakarta last week and slapped the equivalent of one U.S. dollar down on the counter for a ticket, it was a moment of political theatre. It also signaled an early step in the march to presidential elections in mid-2014 in the world's most populous Muslim-majority nation. ...

WASHINGTON/MOSCOW (Reuters) - Russian President Vladimir Putin will unveil a government dominated by loyalists on Monday, leaving Prime Minister Dmitry Medvedev limited scope to pursue his reform agenda and entrenching the Kremlin's grip over the economy's commanding heights. Medvedev, 46, named premier after Putin returned to the Kremlin on May 7, has pledged to launch pro-growth policies and a privatization drive to wean Russia's $1.7 billion economy off its dependence on oil. ...

DOUMA, Syria (Reuters) - A roadside bomb exploded on Sunday about 150 meters (yards) from a United Nations convoy carrying the head of a Syria ceasefire monitoring mission and a senior U.N. official in the town of Douma, a Reuters witness said. Major General Robert Mood's car was stopped at an army checkpoint when the bomb detonated in an nearby alleyway and the convoy left, the Reuters journalist said, adding that there were no reports of casualties. United Nations Under-Secretary-General for Peacekeeping Operations Hervé Ladsous, who is visiting Syria, was also part of the convoy. ...

JOPLIN, Mo (Reuters) - Having the president of the United States speak at commencement would normally be the most memorable day in the life of a high school senior. But not in Joplin, Missouri, where President Barack Obama's commencement address on Monday will come one year after the deadliest tornado in the United States in six decades killed 161 people. "I'm pretty sure we will remember the tornado more than Obama's speech," said graduating senior Ethan Ritschel. ...

VIENNA (Reuters) - The U.N. nuclear supervisor flew to Tehran on Sunday voicing optimism he could reach a deal to investigate suspected atom bomb research - a possible breakthrough that Iran may hope could help ease Western sanctions pressure and deflect threats of war.

Nothing is certain but I stay positive," Yukiya Amano, director general of the International Atomic Energy Agency, said at Vienna airport, adding "good progress" had already been made. ...

PHOENIX (Reuters) - An Arizona wildfire whipped up by winds and dry conditions threatened to trigger more evacuations on Sunday, just as firefighters were nearly done battling the biggest of four blazes in the state.

CAMP ROUND MEADOW, Maryland (Reuters) - Prime Minister David Cameron urged countries on Saturday to put in place strong contingency plans to deal with fallout from the euro zone debt crisis as fears grow that Greece could be forced out of the European single currency.

It carried maximum sustained winds near 50 miles per hour. ...

NEW YORK (Reuters) - Normally a big decline would set up Wall Street for a technical rebound. But that may not be the case this week, even after the market posted its worst weekly loss for the year and the S&P fell for six straight sessions. With the corporate earnings season drawing to an end and recent U.S. economic data raising doubts about the pace of growth, the S&P 500, which is down 7.3 percent so far in May, could decline further this week as concerns about the financial health of Europe persist. ...
