Algiers  -  Sahrawis living in the Algeria-based Tindouf camps "should be free to advocate options other than independence for the Western Sahara without any imposed restrictions by the Polisario leaders," said Saturday Human Right Watch (HRW). "The Polisario Front should ensure that camp residents are free to challenge its policies and leadership and advocate options other than independence for the Western Sahara", said HRW, calling on the leaders of the separatist movement to "end military court jurisdiction over civilians and eradicate all vestiges of slavery".
