rim Agreement -
permanent status to be determined through further negotiation;
Israel continues construction of a "seam line" separation barrier
along parts of the Green 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

World
stretching over 250,000 km, the world's 329 international land
boundaries separate the 193 independent states and 73 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; maritime states have claimed
limits and have so far established over 130 maritime boundaries and
joint development zones to allocate ocean resources and to provide
for national security at sea; boundary, borderland/resource, and
territorial disputes vary in intensity from managed or dormant to
violent or militarized; most disputes over the alignment of
political boundaries are confined to short segments and are today
less common and less hostile than borderland, resource, and
territorial disputes; undemarcated, indefinite, porous, and
unmanaged boundaries, however, 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 around the world; disputes over islands at sea or in
rivers frequently form the source of territorial and boundary
conflict; other sources of contention include access to water and
