A Russian passenger plane crashed near Moscow after take-off on Sunday and the Kremlin said all 71 people on board were feared dead.
It was not immediately clear what had caused the crash, which happened as temperatures hovered around minus 5 degrees Celsius with periodic snowfalls.
Investigators said they had opened a criminal case into the incident and were looking at all possibilities.
The plane, a short-haul AN-148 operated by Russia’s Saratov Airlines, was en route from Moscow to the provincial city of Orsk in the Orenburg region about 900 miles (1,500 km) southeast of the Russian capital.
