The Security Council unanimously voted Tuesday to approve an independence referendum for Western Sahara, where Marxist guerrillas haven been battling Morocco's occupation forces for 13 years.

The 15-0 Security Council vote approved the appointment of a special representative of the secretary-general to monitor a referendum that would result in Western Sahara's independence or affiliation with Morocco.Secretary-General Javier Perez de Cuellar reminded the members of the council that on Aug. 30, representatives of the Polisario independence movement and Morocco met with him in Geneva to approve the referendum and peace plan, with certain reservations.

Perez de Cuellar said a special representative from his office, a civilian unit, a military unit and a security unit would work for peace in the area.
