Ceuta and Melilla are Spanish exclaves on the north coast of Africa, separated from the Spanish mainland by the Strait of Gibraltar and the Mediterranean Sea. Morocco claims both cities and wants Spain to return them, just as the other plazas de soberanía on the North African coast. Spain rejects these claims and says the cities are fully Spanish. As Ceuta and Melilla are part of Spain, people can cross their land borders from Morocco to enter the European Union - even though they are physically still in North Africa. Despite high fences and strict border patrols, migrants try to find their way to the EU via these exclaves.
