President Abdel Fattah ei-Sissi's remarks came as a top US intelligence official said it was "unlikely" IS was involved in the crash of the Kogalymavia Airbus A-321 over the Sinal peninsula on Saturday. "When there is propaganda that it crashed because of Isis, this is one way to damage the stability and security of Egypt and the image of Egypt" Mr Sissi told the BBC, using an alternative acronym for the IS."Believe me, the situation in Sinai, especially in this limited area, is under our full control," he said. Both Cairo and Moscow have played down a claim by Egypt's IS branch that it brought down the plane which was bound for St Petersburg in Russia from the Red Sea resort of Sharm el-Sheikh.
