Spanish intelligence services (CNI) alerted Moroccan authorities regarding planned mass attempts to breach the border in Ceuta. Internal notes and WhatsApp messages reveal the CNI analyzed social media warnings about coordinated efforts “to assault by fence and sea.” This information was reportedly communicated to Moroccan intelligence services the day before a significant migrant surge occurred in Ceuta. The warnings detailed potential large-scale gatherings aimed at overwhelming border controls. This proactive sharing of intelligence suggests a collaborative effort to manage potential security risks. The incident highlights the ongoing challenges related to migration and border security in Ceuta and the reliance on cross-border information exchange. Details of the specific nature of the coordinated efforts remain under investigation.
