The U.S. Department of State has a new travel warning system, ranking danger spots around the globe from one to four.
Five states from Mexico have been classified under the most dangerous ranking.
For the State Department, Mexico is level 2, which warns American travelers to be cautious while visiting.
Mexico City ranked level 2, but Arizona’s neighbor, Sonora, is level 3, meaning: reconsider travelling to that state.
And five Mexican states are level 4, the highest rank. Those include: Colima, Guerrero, Michoacán, Sinaloa and Tamaulipas.
These are places where the American Government advices zero traveling, similar to warnings for Iraq and North Korea.
This travel warning replaces the one issued last August that still used a system without rankings.
