Viktor Ozerov, head of the defense affairs committee at the upper house of Russian parliament, says in remarks carried by the state news agency RIA Novosti that he "totally excludes" terrorism as a possible cause of the crash.
The plane was en route to Russia's air base in Syria with 92 people on board when it crashed shortly after taking off from the resort town of Sochi. At least one body has been found and there is no word on whether anyone survived, AP reported.
The Defense Ministry has released a list of the passengers. They include 64 members of the Alexandrov Ensemble, among them its leader, Valery Khalilov.
