...... "Maybe accompanied by a local it would be easy." ..... if caught by the Moroccan security forces attempting without permission (which you'er unlikely get), after some rough treatment and maybe a "fine", you'll be deported either back North to Morocco or out of Morocco altogether. While your unfortunate Sahrawi friend(and family) will feel the full force of an oppressive regime. Sahrawi in company with foreigners are discouraged and separated citing security issues, the foreigner sent on their way, the Sahrawi detained and then some.!
Tensions fluctuate, small local issues can quickly get out of hand, one thing for sure is how the security forces deal with any incident. While you can always go home, bolt back to safety, the Sahrawi have nowhere to go, so be careful what you might get a young lad into. ... and to mention as far as I know Awsard is on the Moroccan side of the the Berm (big sand wall) not on the Algerian side, so this place is surrounded 24/7/365.
Earlier this year the Moroccan Government expelled the UN observers/peace-keepers only to partially allow them back some months latter.
This dispute is damaging to both sides, a blight on Morocco's good reputation for being progressive, the country has made huge strides in health and education, business and tourism, yet fails to deal fairly with Sahara Question.
I'm amazed at the polarised views of my many Moroccan friends in the issues above, for some no compromise could be considered, the Sahrawi are Satan incarnate in the extreme, for others they want them to be just Moroccans like themselves, except the Sahrawi just want to be themselves.
