Russian Transportation Minister Maxim Sokolov said, Sunday, that all possibilities, including terror, are being investigated in the morning crash of a Russian plane in the Black Sea. Agence France Presse reports that when he was asked if a terror attack could have been behind the crash, Sokolov said: "It is premature to speak of this."

Among the 92 passengers and crew on the Syrian-bound plane were 64 members of the Alexandrov Ensemble, the army's official musical group also known as the Red Army Choir, and its conductor Valery Khalilov.
