Morocco vs. Algeria

Morocco protests Spain's control over the coastal enclaves of Ceuta, Melilla, and Penon de Velez de la Gomera, the islands of Penon de Alhucemas and Islas Chafarinas, and surrounding waters; both countries claim Isla Perejil (Leila Island); discussions have not progressed on a comprehensive maritime delimitation, setting limits on resource exploration and refugee interdiction, since Morocco's 2002 rejection of Spain's unilateral designation of a median line from the Canary Islands; Morocco serves as one of the primary launching areas of illegal migration into Spain from North Africa; Algeria's border with Morocco remains an irritant to bilateral relations, each nation accusing the other of harboring militants and arms smuggling; the National Liberation Front's assertions of a claim to Chirac Pastures in southeastern Morocco is a dormant dispute

Algeria and many other states reject Moroccan administration of Western Sahara; the Polisario Front, exiled in Algeria, represents the "Sahrawi Arab Democratic Republic" which Algeria recognizes; the Algerian-Moroccan land border remains closed; dormant disputes include Libyan claims of about 32,000 sq km of southeastern Algeria and the National Liberation Front's (FLN) assertions of a claim to Chirac Pastures in southeastern Morocco.
