An estimated 49,000 migrants have crossed illegally into the Spanish enclave of Ceuta from Morocco in the last 24 hours, throwing the city in North Africa into disarray and causing a major headache for Pedro Sanchez’s government.At least 19 people have been found dead in the water since the mass movement by land and sea into the tiny Spanish-held spit in North Africa on Thursday, and security forces are still wrestling to re-establish control of the border.At the gates into Ceuta, Moroccan authorities had deployed water cannon trucks and pushed people back.

In 2025, the number rose again, with 3,523 people entering Ceuta by land, according to figures from Spain's Interior Ministry.The population of Ceuta is roughly 83,500 to 85,000 people.Where is Ceuta?In the week before 30 July, more than 1,500 people reached Ceuta by sea, according to the territory's regional leader — already more than half the number recorded during the whole of 2024.The latest influx is on an unprecedented scale, with the Spanish government’s estimate of 49,000 arrivals in 24 hours dwarfing the numbers normally recorded over an entire year.To reach Ceuta, migrants often swim from the Moroccan town of Fnideq, covering about 5 kilometers (3.1 miles) to reach Spanish territory.Others attempt the crossing from the nearby town of Belyounech, where the distance is shorter.Spain's overall immigrant population has grown considerably in recent decades, with around 10 million people in the country of 50 million having been born elsewhere.Many are from Colombia, Venezuela and Morocco, and work in key sectors of the Spanish economy, including agriculture, tourism and the service sector.How many people have died?At least 19 people are reported to have died while attempting to reach Ceuta.The toll has risen as authorities recovered bodies and assessed the consequences of the mass movement. Earlier reports had put the number of deaths lower.The deaths have added a humanitarian dimension to what is rapidly becoming a major political and security crisis for Spain, Morocco and the wider EU.
