The Polisario Front has denounced terrorism and attacks against civilians, and sent condolences to Morocco after the 2003 Casablanca bombings. It describes its struggle as a "clean war of national liberation". Since 1989, when the ceasefire was first concluded, the movement has stated it will pursue its goal of Western Sahara's independence by peaceful means as long as Morocco complies with the ceasefire conditions, which include arranging a referendum on independence, while reserving the right to resume armed struggle if terms are objectively breached, for example, if the referendum is not conducted. Mohamed Abdelaziz has repeatedly stated that the Moroccan withdrawal from the 1991 Settlement Plan and refusal to sign the 2003 Baker Plan would logically lead to war from its perspective if the international community does not step in.
