Morocco's autonomy proposal for the Sahara is "serious" and "credible", said, on Sunday in Rabat, US Under Secretary for Political Affairs William Burns.

A broad autonomy within a multicultural Morocco is the solution to the Sahara dispute, said the Spanish journalist and writer Javier Valenzuela, who called upon the Spanish left to make a "major revision of its position" on this issue.

The relevance of the Moroccan initiative to grant broad autonomy to the Sahara region has been highlighted by experts in international law taking part in a seminar at Dakhla.

US Senator John MacCain said, on Friday in Rabat, that the autonomy plan proposed by Morocco to settle the Sahara issue is "viable".

Morocco's autonomy initiative is the unique solution to the Sahara issue, underlined, Miguel Moran, a United Left leader and member of the Spanish section of the European movement.
