The plane that crashed in the Russian city of Kazan lost altitude quickly and its fuel tank exploded on impact with the runway, eyewitnesses said.
There were high winds and cloudy skies over the airport in central Russia but temperatures were above zero, according to local reports.
This is the latest disaster involving a plane from Russia's regional airlines, which have a poor safety record.
- In April 2012, at least 31 people were killed when a Russian passenger plane crashed shortly after take-off in Siberia.
- In September 2011, a Yak-42 passenger jet carrying members of a major league ice hockey team came down shortly after takeoff and burst into flames near the Russian city of Yaroslavl, killing 44 people.
- Russia and the former Soviet republics combined had one of the world's worst air-traffic safety records in 2010, with a total accident rate almost three times the world average, according to the International Air Transport Association.
