Princess Cruises has canceled calls in Puerto Vallarta for the rest of the year, citing safety concerns.

The move comes three months after Princess and several other lines pulled out of nearby Mazatlan, Mexico, also over safety concerns.

"As the safety and security of our passengers and crew is our highest priority, and based on the continued violence in these areas, we've made the decision to cancel our calls to Puerto Vallarta and Mazatlan," Princess spokeswoman Karen Candy tells USA TODAY.

In recent months, Carnival, Holland America, NCL and others have canceled visits to Mazatlan following a spate of violence tied to the escalating drug war, but Princess is the first line to nix calls in Puerto Vallarta. In May, a Canadian man living in Puerto Vallarta was stabbed to death and robbed in his home. Princess declined to say how the incident, or any other specific incident, informed the deployment changes.
