Spain and Morocco have been at odds for many years.
They have disagreed about territories, immigration and support for rebels in the region.
But a visit by the Spanish Prime Minister Pedro Sanchez to Rabat this week is raising hopes of improved ties.

The Polisario Separatist group, which wants an independent state in the region, has rejected that plan.
So, what would it take to solve this long-running conflict?
