Mustapha Salma Ould Sidi Mouloud was arrested on Tuesday evening by the militia of polisario upon his arrival in the border post leading to the Tindouf camps, coming from the Mauritanian territory, international media reported on Tuesday.

Rguibat-Sellam tribe leaders and dignitaries urged the UN and human rights NGOs to intervene for the release of all the persons arrested in the Tindouf camps, condemning this situation that violates human dignity and human rights.

The Sahrawis want to recover their right stolen by the polisario which does not represent them, Mustapha Salma Ould Sidi Mouloud, chief inspector of the polisario's police, said.

Spain reiterated, on Tuesday, its support for searching for a "just and lasting" solution for the Sahara issue under the aegis of the United Nations.

 By deciding to return to Tindouf (southwestern Algeria) to support the Moroccan autonomy proposal for the Sahara, Mostafa Salma Ould Sidi Mouloud "calls the polisario's bluff," said the international weekly "Jeune Afrique" in its latest issue.
