legal status of territory and issue of sovereignty
unresolved; territory contested by Morocco and Polisario Front
(Popular Front for the Liberation of the Saguia el Hamra and Rio de
Oro), which in February 1976 formally proclaimed a
government-in-exile of the Sahrawi Arab Democratic Republic (SADR),
led by President Mohamed ABDELAZIZ; territory partitioned between
Morocco and Mauritania in April 1976, with Morocco acquiring
northern two-thirds; Mauritania, under pressure from Polisario
guerrillas, abandoned all claims to its portion in August 1979;
Morocco moved to occupy that sector shortly thereafter and has since
asserted administrative control; the Polisario's government-in-exile
was seated as an Organization of African Unity (OAU) member in 1984;
guerrilla activities continued sporadically, until a UN-monitored
cease-fire was implemented 6 September 1991
