3. Damascus, Syria
Syria has been ensnared in a violent civil war since March 2011, with uprisings and protests taking place daily against President Assad’s regime. Then in August 2013, Assad’s troops used chemical weapons against Syrian citizens. The continuous violence has caused a temporary suspension of commercial flights and closure of roadways. The threat of terrorism and kidnapping is very high in Damascus and the surrounding suburbs. While its a historically and culturally rich city, the Foreign and Commonwealth Office advises that Damascus is one of the worst travel destinations in the world right now.
