Spain’s government said on Friday it would impose border controls on flights and ships arriving from Italy from midnight Saturday until September 7, amid a dispute with its neighbouring country over irregular migration.

The measures will include passport, nationality and visa checks for Italian passengers and travellers from other countries arriving from Italy, citing “persistent irregular migratory pressure” from the country.

Spain said the measures would remain in place for as long as Italy maintained its own border controls, which Rome said were introduced after a mass influx of about 72,000 migrants into Spain’s North African enclave of Ceuta on July 30.

Italy said earlier on Friday that it would not bow to “ultimatums or impositions” from Spain and would keep its border controls on arrivals from the country until at least August 15.

Spain had threatened to introduce reciprocal measures on Italian travellers unless Rome lifted its controls by Sunday, following the reported surge of migrants from Morocco into Ceuta.

In a statement, the Italian government said it would only reconsider the measures once it was satisfied that there were no security or terrorism threats, no risk of another migration surge and no irregular migrants moving towards European territory.
