Egyptian President Abdel Fattah al-Sissi today urged people to wait for the outcome of an investigation to determine the exact reason a Russian airliner crashed, killing all 224 people on board.
The jihadist Islamic State group has claimed it downed the plane on Saturday in Egypt's restive Sinai Peninsula, but experts have expressed extreme doubt over its ability to hit an airliner at cruising altitude.
"In such cases, leave it to specialists to determine the cause of the plane crash because it is a subject of an extensive and complicated technical study," state news agency MENA quoted Sisi as telling a gathering of army officers.
