Social media rumors sparked a migration surge from Morocco to Spain's territory of Ceuta. Posts on Instagram, Facebook, and TikTok convinced thousands of migrants that the border was open. Within days, an estimated 72,000 people reached Ceuta, the largest surge in years. Most have since returned to Morocco. Many migrants also misunderstood Spain's immigration rules, thinking they could stay. Both Moroccan and Spanish authorities were unprepared. They blamed misinformation and smuggling networks. Economic struggles in Morocco continue to drive young people to seek opportunities abroad.
