Mexican federal police and soldiers are taking over police duties in the Pacific coast resort of Acapulco to ensure the safety of vacation visitors.

The move was announced Wednesday as officials said troops and federal police will also take over policing in 20 more townships north of Acapulco in a region known as Tierra Caliente, or the Hot Lands.

A similar plan had already been implemented in 16 townships, bringing the total now under federal patrols to 36. National Security Commissioner Monte Alejandro Rubido said the patrols will be under the command of the army.

The once-glamorous resort of Acapulco has been hit by reservation cancellations because of protests and violence. In late November, the U.S. Embassy advised U.S. citizens "to defer non-essential travel to Acapulco, by air or land."
