Emirates Airlines President Tim Clark said on Sunday he expected the crash of a Russian passenger jet in Egypt would result in demands for stringent aviation security worldwide.

Speaking at the Dubai Airshow, Clark added that he had ordered a security review, but was not suspending any flights as a result of the disaster.

Islamic State militants fighting security forces in Egypt's Sinai Peninsula claimed that they brought down the Airbus AIR.PA A321, which crashed 23 minutes after taking off from the resort of Sharm El-Sheikh a week ago, killing all 224 passengers.
