Booked flights to Turkey about 3 months ago. We bought tickets that we can cancel and get most of money refunded. Have not yet booked accommodation.
The Foreign Office advice is that the only part of Turkey they advise not to travel to is the part next to the border with Syria.
However, in view of the volatile situation in the Middle East and the fact Turkey shares a large border with Iran, would it be best to cancel? Can't quite decide. It was going to be a holiday of a lifetime. We tried to go to Turkey 30 years ago and had to cancel that as I had a slipped disc.
