A Russian plane carrying 65 passengers and six crew members crashed outside Moscow on Sunday, shortly after taking off from the capital’s Domodedovo airport, killing all on-board.

The tragic incident took place as an Antonov An-148 plane operated by the domestic Saratov Airlines was flying to Orsk, which is a city in the Urals. The plane crashed at a remote location in the Ramensky district where there were no inhabitants on-ground. While the remoteness of the location saved lives on ground, it proved to be a hurdle for rescue workers who had to walk for hours to reach the crash site.

“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.

According to reports, eye witnesses from the village of Argunovo saw a burning plane falling from the sky. The state television also aired video of the crash site which showed parts of the plane wreckage in the snow.

It has been reported that the plane disappeared from the radar four minutes after take-off. So far an exact cause of the crash is not known but bad weather and human error are the likely causes. Russia is currently facing some really harsh weather with record-high snowfall and poor visibility.

The Russian-made plane was reportedly seven years old and bought by Saratov Airlines from another Russian airline a year ago.

President Vladimir Putin offered “his profound condolences to those who lost their relatives in the crash,” his spokesman Dmitry Peskov said.
