9. Damascus, Syria
The worst city in the world to live in is Damascus, Syria. This city was established about 5,000 years ago. However, since it is currently in an active war zone, it is no longer a desirable place to live. Many of the refugees fleeing to Europe are Syrians.
The US State Department ranks Syria as a Level 4: Do Not Travel. They cite the use of deadly force against civilians including ballistic missiles and chemical weapons as the reason for the ban.
