Spanish Foreign Minister Arancha Gonzalez Laya announced on Tuesday that her government is considering including Melilla and Ceuta, Spain’s enclaves in North Africa, fully in Europe’s passport-free Schengen area.

Moroccan nationals from the towns surrounding the enclaves can currently enter without a visa, but need one to travel by sea or air into continental Spain or other Schengen member countries.

This comes amid a row between Morocco and Spain over issues related to Western Sahara, a region Morocco claims sovereignty over.

Laya declined to comment on the row, noting that her ministry is working “under discretion.”
