Everything depends on the terms of the contract. Tour to Turkey will be canceled, of course, part of the money (again, based on conditions) will be withheld. To change the tour, as suggested in the days of the military conflict in Egypt (when there was an official ban on visits) can not be, only through cancellation. If there is an official ban on visiting the country, then options will be offered, but not everything is so bad there.

Ie. want to change - cancel, reconcile with fines, pay extra for the new tour.

And yes, not all media objectively reflect the events in the country.
