Some international airlines, including German Lufthansa and Air France, are avoiding Sinai on their international routes until the cause of the crash can be clarified.

Today, 211 Russians and 3 Ukrainian citizens died on the Russian Airlines that crashed flying at 9,450 meters (31,000 feet) above Sinai, Egypt.

Russian President Vladimir Putin has ordered an official investigation into the crash of the flight, and for rescue teams to be sent to the crash site.

ISIS took responsibility in a tweet, but many experts do not yet believe it was a terror attack and think a malfunction on the Airbus A320 caused the plane to dive out of the sky.

Security experts say a plane flying at that altitude would be beyond the range of a shoulder-launched surface-to-air missile (Manpad), which Sinai militants are known to possess.

British Airways and easyJet said their routes were regularly reviewed, but that they had no plans to alter their routes to and from Sharm el-Sheikh.
