The US State Department issued a travel warning on five states in the Mexican region due to drug cartels and criminal activity in these regions.
The warning advises US citizens not to travel to five Mexican states: Tamaulipas on the U.S. border and Sinaloa, Colima, Michoacan and Guerrero on the Pacific coast.
The State Department had previously discouraged travel to all or part of those states but the new warnings are sterner, placing them on a level 4 warning, the highest level of potential danger.
