French plane lost in ocean storm
An Air France plane carrying 228 people from Brazil to France has vanished over the Atlantic after flying into turbulence, airline officials say.
The Airbus sent an automatic message at 0214 GMT, four hours after leaving Rio de Janeiro, reporting a short circuit. It may have been damaged by lightning.
It was well over the ocean when it was lost, making Brazilian and French search planes' task more difficult.
France's president said the chances of finding survivors were "very small".

"It is a catastrophe the likes of which Air France has never seen," Nicolas Sarkozy said after meeting relatives and friends of passengers at a crisis centre at Charles de Gaulle airport.
Earlier, Air France chief executive Pierre-Henri Gourgeon told reporters: "We are without a doubt faced with an air disaster."
He added: "The entire company is thinking of the families and shares their pain."
Flight AF 447 left Rio at 1900 local time (2200 GMT) on Sunday. It had 216 passengers and 12 crew on board, including three pilots. The passengers included one infant, seven children, 82 women and 126 men.
Air France confirmed that there had been 61 French and 58 Brazilians on board.
Among the other passengers were 26 Germans, nine Chinese, nine Italians, six Swiss, five Britons, five Lebanese, four Hungarians, three Irish, three Norwegians and three Slovaks.Lightning theory doubts
The Airbus 330-200 had been expected to arrive in Paris at 1110 local time (0910 GMT).
Tom Symonds, BBC News transport correspondent The Airbus A330 airliner is likely to have begun its journey tracking the coast of Brazil northwards before striking out across the Atlantic. A few hundred miles from the shore, radar coverage peters out - from there on, crews use high frequency radio to report their position.
The Brazilian Air Force says the plane left radar screens near the islands of Fernando de Noronha, 230 miles from the coast. The firmest clue to its fate comes from the data message sent via a satellite network at 0214 GMT reporting electrical and pressurisation problems. This suggests whatever happened, happened before the crew could put out a mayday radio call. It was likely a sudden and catastrophic emergency. Even a double engine failure at cruising altitude would normally give the crew around half an hour's gliding time.
Air France says the plane may have been struck by lightning - the cause of around a dozen major air crashes in the last 50 years - but it rarely results in tragedy. More likely lightning damaged electrical systems, possibly leading indirectly to the plane's ditching.
Although passengers survived a landing on the Hudson River in New York in January - it is rarely successful, especially in the middle of an ocean the size of the Atlantic.
It made its last radio contact with Brazilian air traffic controllers at 0133 GMT (2233 Brazilian time) when it was 565km (360m) off Brazil's north-eastern coast, Brazil's air force said.
The crew said they were planning to enter Senegalese airspace at 0220 GMT and that the plane was flying normally at an altitude of 10,670m (35,000ft).
At about 0200 GMT, the captain reported entering heavy turbulence caused by Atlantic storms, French media report.
At 0220, when Brazilian air traffic controllers saw the plane had not made its required radio call from Senegalese airspace, air traffic control in the Senegalese capital was contacted.
At 0530 GMT, Brazil's air force launched a search-and-rescue mission, sending out a coast guard patrol plane and a specialised air force rescue aircraft.
France is despatching three search planes based in Dakar, Senegal, and has asked the US to help with satellite technology.
"The plane might have been struck by lightning - it's a possibility," Francois Brousse, head of communications at Air France, told reporters in Paris.
David Gleave, from Aviation Safety Investigations, told the BBC that planes were routinely struck by lightning, and the cause of the crash remained a mystery.
"Aeroplanes get hit by lightning on quite a routine basis without generally any problems occurring at all," he told BBC Radio Five Live.
"Whether it's related to this electrical storm and the electrical failure on the aeroplane, or whether it's another reason, we have to find the aeroplane first."
France's minister responsible for transportation, Jean-Louis Borloo, ruled out hijacking as a cause of the plane's loss.'No information'
Mr Sarkozy said he had met "a mother who lost her son, a fiance who lost her future husband".

"I told them the truth," he said afterwards. "The prospects of finding survivors are very small."
Finding the plane would be "very difficult" because the search zone was "immense", he added.
About 20 relatives of passengers on board the flight arrived at Rio's Jobim international airport on Monday morning seeking information.
Bernardo Souza, who said his brother and sister-in-law were on the flight, complained he had received no details from Air France.
"I had to come to the airport but when I arrived I just found an empty counter," he was quoted as saying by Reuters news agency.
Air France has opened a telephone hotline for friends and relatives of people on the plane - 00 33 157021055 for callers outside France and 0800 800812 for inside France.
This is the first major incident in Brazilian air space since a Tam flight crashed in Sao Paulo in July 2007 killing 199 people. http://news.bbc.co.uk/2/hi/americas/8076848.stm#map
Passenger nationalities revealed
Most of the passengers on board the Air France plane which has disappeared over the Atlantic were Brazilians and French nationals, airline officials said.
Air France confirmed 61 French and 58 Brazilian passengers were among the 216 passengers on board flight 447.
A list provided by Brazil's authorities showed 26 Germans were also on board as well as nine Chinese and nine Italians.
Six Swiss, five British, five Lebanese and four Hungarians were on the flight from Rio de Janeiro to Paris.
Those on board also included three Irish, three Norwegians, three Slovaks, two Americans two Moroccans, as well as individuals from Argentina, Austria, Belgium, Canada, Croatia, Demark, the Netherlands, Estonia, the Philippines, The Gambia, Iceland, Romania, Russia, South Africa, Sweden and Turkey.
No details have yet been given about the 12 crew.Phone line
"Air France expresses its deepest sympathy to the relatives and friends of the passengers and crew who were on board this flight," the airline said in a statement on its website.
It said it was doing its utmost to support relatives and friends, and had set up counselling services at both the French and Brazilian airports.
A special phone line has been set up for relatives and friends.
In France, the number is 0800 800 812. In Brazil, the number is 0800 881 20 20 and for those in other countries the number is 0033 1 57 02 10 55.
The Michelin tyre company earlier said three of its executives were on the flight, including the president of its South American operations, Luiz Roberto Anastacio.
It is also believed that Erich Heine, an executive board member at the German steelmaker ThyssenKrupp, was on board.
He is also the chairman of the company's Brazilian unit - Companhia Siderurgica do Atlantico - a joint venture between ThyssenKrupp and a Brazilian mining company. http://news.bbc.co.uk/2/hi/americas/8077858.stm
