A Russian security delegation left Cairo on Thursday after a 4-day visit inspecting Egypt's civil airports, Al-Bawaba News reported Thursday. The delegation's visit came within the Civil Aviation Accord signed between both countries to inspect security measures prior lifting the air-traffic ban imposed after Russia's passenger flight that crashed in Sinai on Oct. 31, 2015. Egypt's civil aviation officials revealed that the delegation praised the applied security procedures as well as the modifications that were implemented upon some passenger halls to boost high security standards for incoming tourists.
