Meanwhile, the quality of the fuel used by the Russian airliner that crashed in Egypt on Saturday, killing all 224 people on board, met all necessary requirements, Russian Volga region transport prosecutors said on Sunday, according to RIA.
Egyptian and Russian investigators will begin examining within hours the contents of the two black boxes recovered from the Russian airliner that crashed over Egypt's Sinai Peninsula on Saturday, judicial and ministerial sources said.
