147 civilian staff members, 39 of whom were internationally recruited and 108 locally recruited. Buffer Zone The United Nations Buffer Zone in Cyprus is a demilitarised zone, patrolled by UNFICYP, that was established in 1974 following the Turkish invasion of Cyprus, and de facto partitions the island into the area controlled by the Government of Cyprus (which is the de jure government for the entire island save for the British Sovereign Base Areas) in the south and that under the illegal Turkish occupation in the north. The zone runs for more than along what is colloquially known as the Green Line and has an area of . The zone stretches for 180 km from the western part of near Kato Pyrgos to the east just south of Famagusta. It cuts through the center of the old town of Nicosia, separating the city into southern and northern sections. There is also a buffer zone around the Kokkina exclave in western Cyprus. The width of the zone ranges from in central Nicosia, to at the village of Athienou. There is no buffer zone along the common border between the eastern British Sovereign Base Area and the area under the Republic of Cyprus control or turkish army control. The buffer zone is home to some 10,000 people and there are several villages and farms located within. The village of Pyla is famous for being the only village on Cyprus where Greeks and Turks live side by side. Other villages are Dhenia, Mammari, Athienou and Troulli while Lymbia lies partially within the zone. Turkish forces built a barrier on the zone's northern side, consisting mainly of barbed-wire fencing, concrete wall segments, watchtowers, anti-tank ditches, and minefields. This line is also referred to as the Attila Line on some maps, named after the Turkish code-name for the 1974 military invasion: Operation Atilla. The closed off zone has become a haven for Cyprus' wildlife, an example of an involuntary park. Finances The annual cost for maintaining UNFICYP is estimated at $57,390,000. This includes the voluntary contribution by the Government of Cyprus of one third of the cost of the force and the annual amount of $6,500,000 contributed by the Government of Greece. Turkey does not directly contribute to the force's budget. The operational cost of UNFICYP just during the period from 16 June 1993 to 31 October 2010 was US$2.91 billion.
