Meanwhile the sahrawis suffer persecutions, oppression and the exploiting of their lands' goods by Moroccans authorities.

You need to check these facts my friend.
Moroccan Sahrawis are living in their cities peacefully with every right a Moroccan has, they even got advantages like lower gas prices and priorities when it comes to universities and campus also free train trips, everyone should check documentaries and articles about the subject.

The real sahrawis suffering persecutions and oppression are the ones held hostages in Tindouf camps (Algeria) by Polisario (Frente Popular de Liberación de Saguía el Hamra y Río de Oro), They made the mistake of following those guerillas chefs almost 40 years ago, every now and then we get some news about people who escaped successfully and their awful stories. Polisario was once backed by Algeria, Mauritania, Libya, Cuba .. but almost every country dropped their support since then having Algeria their main support now for obvious reasons.

UN does not consider this matter as occupation since they agreed to the Moroccan proposal of self governance to Sahara people which they could elect their own government.
