Spanish and Moroccan authorities received warnings about online calls for a mass migrant crossing shortly before tens of thousands of people entered Ceuta, according to declassified documents.
The documents indicate that both countries were alerted to social media messages encouraging a large-scale crossing. The warning came the day before the surge into Ceuta took place.
The material shows that intelligence officials had identified calls circulating online before the movement of people occurred. The information was passed to the relevant Spanish and Moroccan authorities ahead of the crossing.
Ceuta was the destination of the mass entry, with tens of thousands of people reported to have entered after the warnings were issued. The supplied material does not detail the response taken by either country after receiving the alerts.
The disclosure is significant because it shows that official warnings existed before the sudden increase in crossings. The latest known position is that the information has emerged through declassified documents, revealing prior awareness of the planned movement.
