United Nation High Commissioner for Refugees (UNHCR) Antonio Guterres (C) is pictured with unidentified Sahrawi officials during his visit to a refugee camp in Tindouf, on September 9, 2009. Sahrawi Arab Democratic Republic (SADR), was proclaimed by the Polisario Front in the disputed territory of Western Sahara. Western Sahara is a former Spanish colony annexed in 1975 by Morocco. SADR was declared in 1976 by the Polisario Front -- a rebel movement that wants independence for Western Sahara -- which fought a guerrilla war against Rabat's forces before a ceasefire in 1991.
