Istanbul is a metropolitan city with a proven record of advanced security planning and experience. The result is an astonishingly low level of crimes against person, according to Interpol statistics. In June 1996, the city more than proved its ability to organize complex international events easily and with complete safety by hosting the United Nations City Summit Habitat II, during which more than 20,000 foreign visitors, including Heads of State, were the guest of the City of Istanbul without an incident.
