As I am writing this, much is still not known about the 60,000-odd people who swam from Morocco to Ceuta last week. But we do know that many of them saw social-media posts encouraging them to swim to Ceuta and, perhaps, to thereby precipitate a crisis. Ceuta has been a Spanish city since the 16th century, but it is not part of mainland Spain. Nor is it possible to cross from Ceuta to mainland Spain, and therefore into the Schengen Area, the European Union’s free-movement zone, without crossing a checkpoint. Illegal immigrants cannot travel from Ceuta to mainland Spain at all.

Last week, according to El Pais as well as other Spanish, international, and Moroccan media outlets, many Moroccans saw a TikTok video nevertheless claiming that “the Spanish border is open and you can cross without papers,” meaning they could reach the European continent. The video appeared to reference a recent ruling by the Spanish supreme court making it harder to return migrants who arrive by sea, but it was not the only encouragement. Other messages, many of which have now disappeared, told people where to buy wet suits, flippers, goggles, floats, and even waterproof bags for documents and cellphones. Screenshots from Google Maps told them which sections of the Ceuta beach might have fewer police. Moroccan border guards were either unwilling or unable to stop them.

Surprised by the unprecedented numbers and perhaps fearing hundreds would drown—in the end, at least 70 people died in the water, including some children—the Spanish police let them land on the beach. This is when the photographs and videos began to circulate. Among those promoting them were senior members of the Trump administration, and senior leaders of the European far right.

Vice President Vance posted a link to a wildly dishonest Fox News segment that incorrectly described the migrants arriving in “Northern Spain” rather than Northern Africa. “Thank God,” he wrote, “@POTUS was elected and our country’s border no longer looks like this.” Others made more specific threats. Robert Jenrick, a high-profile member of Reform, the British far-right party, wrote that “Ceuta is our future if we don’t secure our border. These men are on their way to Calais.” Nigel Farage, the Reform Party leader, posted a video also claiming that the Moroccans were en route to Britain. Alice Weidel, the leader of the far-right Alternative for Germany (AfD), declared that “Germany is the likely destination.”

These were lies. The Moroccans who swam to Ceuta were never going to make it to Britain, Germany, or anywhere else in Europe. Once again: Access to Ceuta does not give anyone automatic access to the rest of Europe. More to the point, nearly all of those who swam over the border had returned to Morocco by Sunday morning. The Spanish government negotiated their return with the Moroccan government. Moroccan police resumed blocking the border. Spanish police, according to El Pais and the Financial Times, were checking documents in Ceuta to find any Moroccans who illegally remained.

It remains unclear who created the viral posts that encouraged the would-be migrants to believe that they could get to Europe from Ceuta. But those who want to weaken the Spanish government, boost the European far right, and create turmoil inside the EU lost little time in promoting the photographs as soon as they arrived.
