later said that Polisario fighters had attacked Moroccan positions along different parts of the frontline, which stretches hundreds of miles across the desert. The Moroccan government has not yet commented on these claims. Foreign actors Algeria Algeria sees itself as an "important actor" in the conflict, and officially supports the right of the Sahrawi people to self-determination. The efforts invested by Algeria in the Western Sahara conflict, especially at the level of its international relations, are comparable to the ones of an involved party such as Morocco. Morocco's position is that Algeria is part of the conflict and uses the Sahara issue for geopolitical interests that date from the Cold War, claiming that this country in its official communication to the United Nations "presents itself sometimes as 'a concerned party,' other times as an 'important actor,' or as a 'party' in the settlement of the dispute". The United Nations has only ever officially considered Morocco and the Polisario Front parties to the conflict, however acknowledges that other interests may also be involved. Although the United Nations officially considers Morocco and the Polisario Front as the main parties to the conflict, former UN Secretary-General Mr. Kofi Annan viewed Algeria as a stakeholder in the Western Sahara conflict and has invited Algeria, "to engage as a party in these discussions and to negotiate, under the auspices of my Kofi Annan's Personal Envoy". In an interview with the Public Broadcasting Service, in August 2004, James Baker, former personal envoy of the United Nations Secretary to Western Sahara, identified Morocco and Algeria as being both the "two chief protagonists" of the conflict. Some third parties have called for both Morocco and Algeria to negotiate directly to find a solution for the conflict. Since the end of 2016, the UN has gathered stakeholders around roundtables organized in Geneva. The main novelty is that Algeria has been invited to these round tables. Algeria has refused to qualify itself as a "stakeholder" and has defined itself as an "observer". The first roundtable was held on 5 and 6 December, while a new roundtable was scheduled for 21 and 22 March. The refugee camps are located in Algeria and the country has armed, trained, and financed the Polisario for more than thirty years. More than two thousand Moroccan prisoners of war were previously detained on Algerian soil in Polisario camps, but all POWs have since been released. In
