Declassified documents indicate that Spain’s intelligence agency warned Madrid and Morocco about planned attempts by migrants to cross into Ceuta prior to the recent border crisis. The documents reveal prior knowledge of intentions to breach security at the Ceuta border. This raises questions about preparedness and response strategies employed by authorities. The warning suggests the events were not entirely unexpected, despite initial reactions. It is unclear why preventative measures were not fully implemented, given this advance intelligence. The revelation further strains relations between Spain and Morocco following the influx of migrants into Ceuta. Investigations are likely to focus on why the warnings were not acted upon more effectively.
