Russia's ban on flights to Egypt after deadly crash will last months, official says

US intel suggests ISIS bomb brought down plane over Egypt

United States, United Kingdom: High probability crash was terror related

A Russian ban on all flights to Egypt in the wake of a Russian plane crash will last for at least several months, President Vladimir Putin's chief of staff announced Tuesday.

Sergei Ivanov said it would be impossible to radically revise Egypt's security system in a short time, according to Russian news reports. Ivanov spoke during a trip to Finland.

Putin suspended all flights to Egypt on Friday amid security concerns after the Oct. 31 crash of a Russian airliner that killed all 224 people onboard. U.S. and British officials have cited intelligence reports indicating that the plane flying out of Sharm el-Sheikh was brought down by a bomb on board.

Ivanov said Egypt needs to revise its security regime not only in Sharm el-Sheikh, but also at other airports.

Meantime, Egyptian officials say European, Russian and Middle Eastern teams are inspecting security measures at Cairo's international airport relating to passenger and cargo aircraft travelling to their countries.

The head of Cairo's international airport, Maj. Gen. Ahmed Genina says the officials from Russia, Holland, Italy, the United Arab Emirates and Qatar are examining the scanning of passengers, cargo and baggage as they enter the airport and make their way to aircraft. Security guards and caterers are also being inspected.
