Report in Russian states (and please bear with my translation) that officials do not confirm that there was an act of terrorism, but indirect attributes speak about it. Representatives of the Ministry of Internal Affairs say they are already taking measures to increase security at many Russian airports, railway stations, sea and river ports. The TU154 had been in service since 1982, had 30751 hours and was last serviced this month. Less info about the TU134 although the airline state it was one of the best in the fleet. The local authorities in Rostov are preparing to accommode the families of victims. There are also links to the names of those who died (although Sibir have already made a change to the list because of confusion over a transit passenger at Moscow). RIP.
