Spain has introduced temporary border controls for travellers arriving from Italy amid a growing disagreement between the two European countries over migration.

The measures, which began on Saturday, are expected to remain in place until September 7. Spain said the decision was prompted by concerns over continued irregular migration pressure affecting Italy.

The move comes days after Italy introduced similar checks on travellers arriving from Spain. Rome imposed the restrictions after a major influx of migrants into Ceuta, a Spanish territory on the North African coast.

More than 70,000 migrants entered Ceuta from Morocco between July 30 and 31, although the overwhelming majority returned to Morocco within two days.

Italy’s decision to impose controls on Spanish travellers was criticised by Spain’s government, which argued that the move disrupted the Schengen system that allows passport-free travel between participating European countries.

Spain’s response has now intensified tensions between the two countries, which are both members of the European Union and NATO.

The latest measures have also drawn concern from travellers. An Italian tourist who arrived in Madrid said she had not noticed additional checks immediately after leaving her flight but described the situation as unfortunate.

The migrant influx into Ceuta has renewed calls from several European countries, particularly those led by right-wing governments, for stricter controls against irregular migration.

Despite the large number of arrivals in Ceuta, migrants who enter the enclave cannot simply continue into mainland Europe. They must undergo further border controls before travelling onward.

Spain said its temporary measures were necessary in response to the continuing migration situation and would remain effective for about a month.
