The North Sinai prosecution office have summoned air and ground traffic control officials for questioning over the incident.
Egypt's prosecutor general has agreed to allow a Russian government agency to participate in investigating what caused a Russian passenger plane to crash in Egypt's Sinai peninsula on Saturday, state-owned newspaper Al-Ahram's website said.
The North Sinai prosecution office summoned air and ground traffic control officials for questioning over the incident, and ordered a technical team from the Civil Aviation Ministry to analyse the contents of the plane's black box, the newspaper added.
Meanwhile, none of 224 passengers and crew on board a Russian passenger plane survived, medical and security sources said.
Search and rescue team members are still gathering the remains of victims, the sources said.
The Airbus A-321, operated by Russian airline, Kogalymavia with registration number KGL-9268, was flying from the Sinai coastal resort of Sharm el-Sheikh to St Petersburg in Russia when it went down in a desolate mountainous area of central Sinai soon after daybreak.
