In response to a contentious row, Spain has implemented border controls on all air and sea travel from Italy, effective for a month. This measure followed Italy's introduction of similar restrictions last week after an influx of approximately 78,000 migrants from Morocco into the Spanish enclave of Ceuta. The checks, which started at midnight (GMT), are random and apply to about 5%-10% of passengers before they can disembark planes. Spain's socialist leader Pedro Sanchez is at odds with Italy's conservative leader Giorgia Meloni over stricter EU migration rules. The Italian government had claimed its temporary suspension of the Schengen agreement was to prevent migrants from Ceuta entering Italy, a position Madrid dismissed as unfounded. Spain has demanded Italy reverse its checks by Sunday, but Rome maintains they will stay until at least 15 August, citing an anticipated new wave of migration to Ceuta. The Spanish and EU citizens are exempt from additional checks when arriving in Italy, with the extra steps only for non-EU residents. However, there have been long queues and waiting times at several Italian airport terminals due to these measures. Spain says its controls will remain until 7 September unless circumstances warrant a change. Temporary suspensions of the Schengen agreement are not uncommon; Italy also maintains controls on its border with Slovenia. The crisis has prompted concerns about a second wave of crossings from Morocco, with dozens of Facebook posts calling for such an event in mid-August. Several groups promoting these posts have over 100,000 followers. The Spanish prime minister's office is monitoring the situation but does not anticipate a repeat of last week's scenes. The crossings were likely driven by criminal networks spreading disinformation, according to the EU's Migration Commissioner Magnus Brunner, an assertion the Spanish government agrees with. Morocco, which does not recognize Spanish sovereignty over Ceuta and Melilla, has blamed the court for the crisis. The number of people swimming to Ceuta at once has raised questions about why Moroccan border guards did not attempt to stop them.
