Tens of thousands of migrants have surged into the Spanish territory of Ceuta, resulting in a situation where at least 67 people drowned and died. Authorities expect dozens more fatalities and are securing facilities to store bodies. Most migrants have returned to Morocco, but hundreds remain in hiding near Ceuta, complicating authorities' search efforts. The Spanish government plans to install a seawall along the maritime border between Ceuta and Morocco to prevent similar incidents.
