Russia's Defence Ministry has said the wreckage of the military plane that crashed into the Black Sea on Christmas Day - killing all 92 people on board - shows no signs of damage from an explosion or fire, Russian media reported.
More than 3,000 people have been involved in the search for victims' bodies and aircraft debris. Two black boxes have since been recovered.
A number of Russian TV journalists are among the dead in the Russian military plane disaster.
The plane was en route to Russia's air base in Syria when it crashed shortly after taking off from the resort town of Sochi.
Rescuers have so far recovered 10 bodies but all 92 who were on board are believed to have died.
