Morocco is to pull out of a UN buffer zone in the disputed Western Sahara territory. That is according to an official statement from the government. The decision to withdraw from the Guerguerat zone is said to have been personally taken by Morocco's King Mohammed the Sixth. UN Secretary-General Antonio Guterres phoned the monarch to ask him to pull out his troops. Tension in the area flared up last year when Morocco moved into the buffer zone, breaching a UN-backed ceasefire. Morocco recently rejoined the African Union after a three-decade absence due to the world body's recognition of Western Sahara. Morocco maintains that the former Spanish colony is part of its territory.
