"Wall to wall" – this is what now separates Spain and Italy.
Not a physical wall between the two countries, which do not share a common land border, but a barrier created by mutual controls at ports and airports, to the detriment of thousands of travelers, whether on vacation or for other reasons.
After an ultimatum that was turned back, Madrid has decided to respond to Rome in kind. Italy, following the Ceuta crisis, had suspended the Schengen agreement on air and sea borders with Spain for a month.
Thus, at midnight between Friday and Saturday – and until September 7 – controls came into effect for passengers arriving in Spain from Italy.
The Italian Foreign Ministry (Farnesina) has strengthened the assistance of its consulates and offices to Italian citizens who may encounter problems in Spain or while traveling.
However, the situation at the main Spanish airports does not appear to have caused serious consequences so far, nor any disruption to the approximately 250 flights coming from Italy.
Documents were checked continuously on a sample of 5 to 15% of passengers, directly after disembarking from the planes.
This mutual movement, which aims to control third-country nationals, nevertheless constitutes a deep wound for the unity of Europe.
The European Union is convinced that illegal immigration is a "common challenge that must be faced together", and not a battleground between capitals with different political orientations.
"Trust between member states is our most precious resource," recalled EU Home Affairs Commissioner Magnus Brunner, during a phone call with the Interior Ministers of Spain and Italy, Fernando Grande-Marlaska and Matteo Piantedosi.
"Both confirmed that internal border controls are temporary," while he also highlighted "the progress made in the fight against illegal immigration," in an effort to reduce tensions.
Brussels actually wants to avoid the dissolution of the Schengen agreement, by demanding more controls at the EU's external borders, including Ceuta.
