MADRID - Spain has imposed border controls on all air and sea travel from Italy as a row between the two EU countries intensifies. Italy does not share a land border with Spain. Italy has said that Spanish and EU citizens are exempt from additional checks when arriving in Italy, with these extra steps only for non-EU residents. The number of people swimming to Ceuta at once has raised questions about why Morocco’s border guards did not attempt to stop them. The two exclaves have long been a bone of diplomatic contention between Spain and Morocco, which does not recognise Spanish sovereignty over them.
