The new UN envoy for the disputed territory of Western Sahara is visiting the region to assess the possibility of restarting peace talks between Morocco and the pro-independence Polisario Front.
Reports say Horst Koehler - a former German president - met the Moroccan foreign minister Nasser Bourita in Rabat on Monday.
Later in the week he's expected to travel to the Tindouf region of Algeria where he'll meet Polisario officials and some of the refugees living there.
Morocco annexed Western Sahara, a former Spanish colony, in 1975, prompting an insurgency which lasted until a UN-brokered ceasefire in 1991.
