Russian investigators probing the crash of a Dubai airliner in southern Russia that killed all 62 people on board have found one of the plane's flight recorders.

The Boeing 737-800 operated by FlyDubai was carrying 55 passengers, most of them Russian, and seven crew members of various nationalities when it crashed Saturday in the city of Rostov-on-Don while trying to land in strong winds. Russia's Emergencies Ministry said there were no survivors. Four children were among those killed, FlyDubai said.

Vladimir Markin, the spokesman for the Investigative Committee, said experts have found the cockpit conversation recorder and are continuing the search for another one which records parameters of the flight.

The crash's cause wasn't immediately known, but officials suggested it could have been caused by a gust of wind.
