n Line and within the West Bank; Israel
withdrew from four settlements in the northern West Bank in August
2005; since 1948, about 350 peacekeepers from the UN Truce
Supervision Organization (UNTSO), headquartered in Jerusalem,
monitor ceasefires, supervise armistice agreements, prevent isolated
incidents from escalating, and assist other UN personnel in the
region

Western Sahara
Morocco claims and administers Western Sahara, whose
sovereignty remains unresolved; UN-administered cease-fire has
remained in effect since September 1991, administered by the UN
Mission for the Referendum in Western Sahara (MINURSO), but attempts
to hold a referendum have failed and parties thus far have rejected
all brokered proposals; several states have extended diplomatic
relations to the "Sahrawi Arab Democratic Republic" represented by
the Polisario Front in exile in Algeria, while others recognize
Moroccan sovereignty over Western Sahara; most of the approximately
102,000 Sahrawi refugees are sheltered in camps in Tindouf, Algeria

World
stretching over 250,000 km, the world's 322 international land
boundaries separate 194 independent states and 70 dependencies,
areas of special sovereignty, and other miscellaneous entities;
ethnicity, culture, race, religion, and language have divided states
into separate political entities as much as history, physical
terrain, political fiat, or conquest, resulting in sometimes
arbitrary and imposed boundaries; most maritime states have claimed
limits that include territorial seas and exclusive economic zones;
overlapping limits due to adjacent or opposite coasts create the
potential for 430 bilateral maritime boundaries of which 209 have
agreements that include contiguous and non-contiguous segments;
boundary, borderland/resource, and territorial disputes vary in
intensity from managed or dormant to violent or militarized;
undemarcated, indefinite, porous, and unmanaged boundaries tend to
encourage illegal cross-border activities, uncontrolled migration,
and confrontation; territorial disputes may evolve from historical
and/or cultural claims, or they may be brought on by resource
competition; ethnic and cultural clashes continue to be responsible
for much of the territorial fragmentation and internal displacement
of the estimated 6.6 million people and cross-border displacements
of 8.6 million refugees around the world a
