"A commission has been organised, a hotline has been set up for relatives and friends in Novosibirsk. The entire company of Sibir is very upset over this event and and is doing all it can at this time."
A Russian chartered airliner heading from Tel Aviv to Siberia has exploded in flight and crashed off the Black Sea coast with at least 77 people on board.
There are controversial reports that the plane may have been downed accidentally by a missile fired during a military exercise in Ukraine.
But the Ukrainian Defence Ministry has categorically denied that theory.
Russian President Vladimir Putin said terrorism could be the cause.
"A civilian aircraft crashed today and it is possible that it is the result of a terrorist act," Putin told a meeting of visiting European justice ministers in Moscow on Thursday.
Russian Deputy Transport Minister Karl Ruppel said a crew of an Armenian An-24 airliner in the area had informed Russian air traffic controllers in Rostov-on-Don in southern Russia that they saw an explosion aboard a plane flying nearby.
The Armenian plane was flying on a regularly scheduled flight over the Black Sea from the Ukrainian Crimean city of Simferopol to the Armenian capital Yerevan.
Ruppel couldn't immediately say what the cause of the explosion was but confirmed Russian media reports that a blast had occurred on the Russian plane.
The plane, a Tupolev 154, went down in pieces 180 kilometres (114 miles) off the Russian coastal city of Adler, on the Georgian border, said a spokesman for the Ministry of Emergency Situations.
The plane was on its way from Tel Aviv to the Siberian city of Novosibirsk.
It belonged to Sibir Airlines, which is based in Novosibirsk, about 2-thousand-800 kilometres (1,750 miles) east of Moscow, and had been chartered, Sibir officials said.
The Emergency Situations Ministry said there were at least 66 passengers and 11 crew members on board.
The deputy director for security for Sibir airlines, Viktor Alexeyev, was on board the plane, state-controlled O-R-T television reported.
Nikolai Patrushev, the head of Russia's Federal Security Service, told Putin in a televised meeting that Russian officials had first learned of the crash from Armenian officials.
He said planes and ships had been sent to the area of the crash within 15 minutes.
The Emergency Situations Ministry said one body had been recovered so far, as well as some fragments of the plane.
