Morocco's offshore oil dispute

In the coming months US oil company Kosmos Energy will begin drilling off the coast of Western Sahara - a disputed territory claimed by both the government of Morocco and indigenous Saharawis seeking self-determination.

Saharawi protest groups have written an open letter to Kosmos saying the act of drilling would be illegal - a view Kosmos rejects.
