Russia's state aviation authority has banned Egypt's national carrier from flying to Russia. Flights from Russia to Egypt are already suspended after the Metrojet passenger plane crashed in the Sinai last month.
Egypt Air had been the only airline flying between the two countries and the move was to ensure it met safety requirements. EgyptAir runs three flights to Moscow per week on Saturdays, Tuesdays and Thursdays.
Meanwhile, a Russian aviation committee that includes three aviation experts inspected security procedures in Cairo's international airport on Saturday. Egypt's aviation minister Hossam Kamal said "we understand" the Russian side's position and the "exceptional, precautionary measures" it is taking given what the "world is going through" and the "escalation of terrorist threats."
Russian Ambassador to Cairo Sergey Kirpichenko reported that these are temporary security measures and he hopes for the crisis to end as soon as possible they determine the cause of the crash.
Russia's action, effective from Saturday, is a further blow to Egypt's tourism industry.
Russians make up close to one in three of all foreign tourists in Egypt. In 2014, about three million Russian nationals stayed at Egypt's resorts.
