The ill-fated plane, en route to the Syrian port city of Latakia, vanished from the radar screens shortly after taking off from an airfield in the southern Russian city of Adler at 5:40 am Moscow Time (0240 GMT), according to Russian media reports.

"Fragments of the Russian Defense Ministry's Tu-154 aircraft were discovered in 1.5 kilometers from the Black Sea shore of Sochi at a depth of 50-70 meters," the ministry said.

The ministry's spokesman Igor Konashenkov confirmed that 84 passengers including 65 choir members, and eight crew members were on board the plane. The ministry earlier placed the number at 91.

The plane was conducting a routine flight to Russia's Hmeimim air base near Syria's Latakia, said the ministry, adding that among those on board were Russian servicemen and members of the Alexandrov Ensemble, the Russian army's official choir, who were heading to the air base for New Year celebrations.

Among the 84 passengers there were also nine journalists, the ministry noted.

Based on preliminary information, the misfortune was caused by technical malfunction or pilot error, a law enforcement source was quoted as saying.

Russia's Investigative Committee has launched a criminal case over the crash. A defense ministry's commission, headed by Deputy Defense Minister Pavel Popov has departed to Adler.

The Tu-154 is a three-engine medium-range airliner produced by Russian aerospace and defense company Tupolev. It is one of the fastest civilian aircraft in use and widely used in extreme Arctic conditions.
