MADRID, June 15 (Reuters) - Spanish Foreign Minister Arancha Gonzalez Laya said on Tuesday her government is considering including Ceuta and Melilla, Spain"s enclaves in North Africa, fully in Europe"s passport-free Schengen area. Currently, Moroccans from the towns surrounding the enclaves can enter without a visa, but need one to travel by sea or air into continental Spain or other Schengen member countries. The move comes amid a row between Spain and Morocco over issues linked to Western Sahara, a region Morocco claims sovereignty over. Gonzalez Laya declined to comment on the row, saying her ministry is working "under discretion." Reporting by Inti Landauro and Cristina Galan; Editing by Catherine Evans
