The U.S. State Department is expanding expanded its travel advisories to warn of dangers in more parts of Mexico.
The new travel advisory doesn't mention the Caribbean resorts of Cancun or Playa del Carmen by name. But the advisory issued Tuesday says "turf battles between criminal groups have resulted in violent crime in areas frequented by U.S. citizens."
Warnings have also been extended to the states of Veracruz and Chiapas that previously didn't have them.
The department also extended a total ban on personal travel by U.S. government personnel to the violence-wracked state of Guerrero.
U.S. personnel had previously been allowed to fly to the resort of Ixtapa. Personal travel by land in the state and to the resort city of Acapulco had already been prohibited.
