8. Tripoli, Libya
Tripoli has been a major commercial center in Middle East, this was until the beginning of the civil crisis in the Gaddafi regime, during and after which Tripoli has fizzled out many lists such as this one.
With the black market emerging in full during the civil unrest and the Libyan dinar to dollar ratio shooting up, the commercial activities in Tripoli came to a stand still which has given way to a lot of crime and medical problems in and around the city.
