The United States city of Seattle has been the site of occasional, small-scale terrorist incidents. Though several locations in the city have been discovered on target lists of known terrorist cells, as of 2014 the city's Office of Emergency Management believed that a "large-scale attack seems like a low probability event". A 2006 report by the United States Department of Justice indicated that the Washington State Ferries, which have several facilities in Seattle, was the leading "target for maritime terrorism in this country".
