Egyptian President Abdel Fattah al-Sisi meets with tourists during a tour at Sharm el-Sheikh airport, Egypt, 11 November 2015. Al-Sisi vowed to enhance security in the country amid suspicions that a bomb caused the crash of a Russian passenger airliner in Sinai more than a week ago. The Metrojet flight crashed on October 31 shortly after departing from Sharm el-Sheikh en route to the Russian city of St Petersburg, killing all the 224 people on board.
