Investigators will examine today numerous possible causes of one of Russia's worst ever aviation accidents that saw a passenger plane carrying 71 people crash near Moscow minutes after take off, killing everyone on board.
Russia's Investigative Committee said it would consider explanations including human error, technical failure and weather conditions, as the country has experienced record snowfall in recent weeks. But it did not mention the possibility of terrorism.
"Sixty-five passengers and six crew members were on board, and all of them died," Russia's office of transport investigations said in a statement
Three children were among the fatalities on a list published by Russian authorities.
The flight was operated by the domestic Saratov Airlines and was headed for Orsk, a city in the Ural mountains.
More than 400 people and 70 vehicles had been deployed to the crash site, the country's emergency ministry said.
The site was enveloped in heavy snow, making it difficult to access, with emergency workers forced to park their vehicles and reach the wreckage by foot. Others used snowmobiles and drones to survey the scene.
"I felt a shock wave," Maria, a resident of a village near the crash site, told AFP.
"The windows shook," she said
The transport investigations office said the plane disappeared from radar screens around four minutes after take-off.
A regional official said the aircraft's black box had been retrieved.
Saratov was founded in the 1930s and flies to 35 Russian cities. Its hub is Saratov Central Airport in southern Russia.
The governor of the Orenburg region, where the plane was heading, told Russian media that "more than 60 people" on board the plane were from the region.
Putin also cancelled plans to travel to Sochi to meet with Palestinian leader Mahmud Abbas. Instead, the meeting will take place in Moscow.
Local media website Ural56.ru in the Orenburg region showed footage of distressed relatives at Orsk airport, where the plane had been due to land.
Andrei Odintsov, the mayor of Orsk, told Russian state television that six psychologists and four ambulances with medics were working with the families in the small airport.
