That brings us to the end of our live coverage. The recovery operation will resume Wednesday morning at first light. You can continue to get the latest developments on our main story.
As it happened: Airbus A320 crash
- A Germanwings Airbus A320 has crashed in the French Alps near Digne, with 150 people on board
- Flight 4U 9525 was travelling between Barcelona and Duesseldorf
- Passengers believed to include 67 Germans and 45 Spanish citizens
- French President Francois Hollande said he believed none of those on board had survived
- Sixteen German students on a Spanish exchange trip on flight
- Opera singers Oleg Bryjak and Maria Radner also on board
- Search-and-rescue teams reach the crash site at Meolans-Revels
- Cologne-based Germanwings is a low-cost airline owned by Lufthansa
Snowfall: 20cm (until Wednesday)
Max Temp: -2C (28F)
Min Temp: -7C (19F)
The flight came down in a remote area of the French Alps, and the recovery team face a daunting task.
"Considering the conditions there, it will take several days to bring the bodies down, if the weather allows," said Serge Degandt, a local politician to AFP. "At the time of the crash, it was blue skies, visibility was perfect. But it turned bad shortly after."
Opera singers Oleg Bryjak and Maria Radner, who were on the flight, performed for the last time in Wagner's Siegfried on Saturday, the Gran Teatre del Liceu in Barcelona confirmed.
A statement said: "Mrs Radner, who was travelling to Duesseldorf with her husband and baby, both also dead, performed Erda."
Mr Bryjak is pictured below in the same performance. The Liceu theatre has lowered its flags and will observe a two-minute silence tomorrow.
That the flight appeared to get into trouble as it was at cruising height strikes Forbes contributor Dan Reed as unusual. He writes that the "cruise" phase of the flight, i.e. altitudes above 30,000ft (9,100m), is one of the safest, with crashes far more likely during takeoff. What caused the flight to crash is not yet known, but owners Lufthansa are assuming it was an accident.

Victor Barrio, mayor of the Spanish city of Jaca in the Pyrenees, says a woman originally from the city died in the crash along with her baby boy.
He said Marina Bandres, who lived in Britain, had been attending a funeral in Jaca. He did not know if her husband was on the flight with her and their baby son, Julian, who was seven or eight months old.
Students have attended mass in Llinars del Valles, the Spanish town where a group of German teenagers on board the Germanwings flight had been visiting as part of an exchange programme.
Two Australians - a woman and her adult son - were on board the Germanwings flight, the Australian Foreign Minister Julie Bishop has said. "Our thoughts and prayers are with the families of the victims of this shocking tragedy," she said, adding it would be inappropriate to give further details at the present time.
A rescue official says about 10 police officers will spend the night at the crash site to guard it. Lt Col Jean-Marc Meninchini of the regional police rescue service said search operations will resume at daybreak. He said the recovery operation is expected to last a week.
Books of condolence are ready to sign at a sports hall in the south-eastern French village of Seyne-les-Alpes, which has become the hub for all the rescue teams and accident investigators.

Spanish Prime Minister Mariano Rajoy and the Catalan president of this region, Barcelona being the capital, will travel together to the crash site tomorrow. Two politicians, who are poles apart on so many issues, travelling together with be a symbol of unity.
Stephane Duclet, a journalist with French newspaper La Provence, has flown over the crash site.
"From what we were able to see, we had great difficulty in actually locating the plane because very little of it remained. Looking from above, not even the fuselage was intact. All we could make out was small parts."
An area of low pressure will bring fairly strong winds at altitude and also some fresh snowfall to the southern French Alps. The snow could hamper the recovery operation. Some lowering cloud bases and some poor visibility over the mountain tops could affect the safe operation of the recovery helicopters.
Earlier, an opera house in Duesseldorf said bass baritone Oleg Bryjak was on the plane. Barcelona's Gran Teatre del Liceu said Maria Radner, like Mr Bryjak, had performed in its production of Richard Wagner's Siegfried.
Here are a pictures from video taken by news agency AFP, showing the crash site and search and rescue teams:

German Foreign Minister Frank-Walter Steinmeier says the crash site is "a picture of horror". After being flown over the area and briefed by French authorities, he said: "The grief of the families and friends is immeasurable. We must now stand together.
"We are united in our great grief."
The church in Haltern was packed, candlelit and filled with pain.
The priest read out the names of the 16 teenage boys and girls who died today. On behalf of this shocked community he called out the question "Why?". The service was open-ended.
Families and friends are invited to stay all night if they want to light candles and try to find some comfort.

Germany's Spiegel magazine has reported an incident from 2010, when two pilots nearly passed out as they landed in Cologne. The magazine said contaminated cabin air was suspected.
Aviation expert Dr Steven Wright told BBC Radio 4 that as well as examining the flight recorders, investigators will want to look through the maintenance records for the aircraft.
"For an aircraft to lose 32,000ft in eight minutes is really, really unusual," he said.

I'm at the base for all the rescue teams and accident investigators. Helicopters take about four minutes to get to the remote location of the crash site. They found debris and the black box. Night has fallen but helicopters are still taking off. It has been difficult today because of icy rain.

Lufthansa's Europe vice president Heike Birlenbach said at a press conference at Barcelona Airport: "We will do our utmost to support the relatives and the friends of these passengers on board. We are now looking into options and possibilities to bring them to the scene which is not yet confirmed. So we'll have to see whether that makes sense."
An opera house in Duesseldorf says bass baritone Oleg Bryjak was among the 150 people onboard the plane.
The Deutsche Oper am Rhein said Mr Bryjak was on his way back from Barcelona, where he had sung Alberich in Richard Wagner's Siegfried at the Gran Teatre del Liceu.

According to Le Monde, French Interior Minister Bernard Cazeneuve has said the flight recorder will be looked at immediately and has been transferred to the Office of Investigations and Analysis, which describes itself on its website as "the French authority responsible for safety investigations into accidents or incidents in civil aviation".
