Egypt's foreign minister on Monday sharply criticised airlines which said they would no longer fly over the Sinai peninsula after a Russian airliner crashed there at the weekend killing all 224 people on board.
In an interview with Algerian television, Sameh Shoukry said the airlines, which included Emirates, Lufthansa and KLM, were "irresponsible".
Their decision to avoid the Sinai would only fuel suspicions that the Kogalymavia flight did not crash on Saturday due to a technical fault but had "other" causes, he said.
The ultra-extremist Islamic State group claimed it had downed the plane carrying Russian holidaymakers home from the Red Sea Resort of Sharm El-Sheikh to St Petersburg.
The plane was carrying 217 passengers, including 25 children, and seven crew members - mostly Russians.
Egypt denies that terrorists downed the plane.
