The U.S. State Department has issued a travel warning advising travelers to avoid visiting the following five Mexican states: Sinaloa, Colima, Michoacan, Guerrero and Tamaulipas.

Each has been given a level 4 'do not travel' warning — which, to put it in perspective, is the same level as war-torn places like Syria and Somalia.

Crimes including homicide, kidnapping and robbery are widespread in the regions, with Guerrero having suffered from a long history of violence, and criminal organizations operating heavily in Sinaloa.

Below you can see a map of the five states in Mexico deemed most dangerous, with the State of Department giving Mexico a level 2 travel warning overall. To find out more, visit the Mexico Travel Advisory website.
