The United Nations buffer zone between north and south Cyprus ranges in width from a few metres in central Nicosia to several kilometres in the countryside. While it is nominally under the sovereignty of the Republic of Cyprus, it is effectively administered by the United Nations Peacekeeping Force in Cyprus (UNFICYP). The population of the zone is 8,686 (as of October 2007), and one of the mandates of UNFICYP is "to encourage the fullest possible resumption of normal civilian activity in the buffer zone". Inhabited villages located in the buffer zone are legally administered by the Republic of Cyprus but policed by UN peacekeepers.
