Investigators will Monday examine 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.
