Unconfirmed reports say the aircraft belongs to the defense ministry, flying to Syria’s Latakia province.

A Russian Defence Ministry TU-154 plane that had disappeared from radar over the Black Sea with 91 people on board has crashed, the Interfax news agency reported on Sunday, citing an unidentified source.

A rescue team had found the crash site in the Black Sea near the coast of the Sochi, Interfax said.

Other Russian news agencies reported earlier that the Russian aircraft had disappeared from radar soon after taking off from Sochi, a Black Sea resort town.

The plane had disappeared from radar just minutes after take-off from Sochi, the BBC reported, citing Russian media sources.

Sources at the defense ministry said that there were 83 passengers and 8 crew members on board.

Fragments found

Fragments of the plane have already been found at a depth of 50-70 metres at a distance of around 1.5 kilometres (0.93 miles)from the Russian coast, agencies reported

Russia’s RIA news agency, citing an unidentified security source, said preliminary data indicated that the plane had crashed because of a technical malfunction or a pilot error.

The Interfax news agency cited an unnamed source as saying the plane had not sent an SOS signal.

Kremlin spokesman Dmitry Peskov told reporters on Sunday it was too early to say what had caused the crash. President Vladimir Putin was being kept informed of latest developments, Peskov added.

Russia’s Defence Ministry regularly flies musicians into Syria to put on concerts for military personnel. The base they were heading for, Hmeymim, is in Latakia province. It is from there that Russia flies air strikes against Syrian rebels.

Earlier in December, another Russian Defence Ministry crashed in Siberia with 39 people on board as it tried to make an emergency landing near a Soviet-era military base. Nobody was been killed in that incident, though 32 people were airlifted to hospital.
