“U.S. citizens have been victims of violent crime, including murder and kidnapping, predominantly in the Port-au-Prince area. No one is safe from kidnapping regardless of occupation, nationality, race, gender or age,” according to a statement on the department’s website.

The department noted that in recent months, travelers arriving in Port-au-Prince on flights from the U.S. were attacked and robbed shortly after departing the airport. At least two U.S. citizens were shot and killed in robbery and kidnapping incidents in 2012.
