Russian airline Metrojet  is planning to demand compensation from Egyptian authorities over the crash of its Airbus A321 passenger jet over Sinai on 31 October, saying it was “caused by a terrorist attack,” the Russian news agency TASS has reported.

Forbes quoted Businessman Ismail Lepiyev, who owns the company, as saying: “Egypt is Russia’s partner in many spheres, these are the relations that have been built over decades, and we respect this and will try to agree to the last on compensation without judicial steps.”

He said the airline expects Egypt to declare the official results of the investigation.

The plane belonging to Russia’s Kogalymavia airline was en route from Sharm El-Sheikh in Egypt to St Petersburg in Russia when it crashed over Sinai, killing all 224 people on board, mainly Russians.

Russian federal security officers later said the incident was a “terrorist attack” caused by a homemade bomb containing 1kg of explosive material. As a result, Russia announced it was temporarily suspending flights to Egypt for security reasons.
