Dozens of Facebook and Instagram accounts spreading AI-generated videos depicting the United Kingdom as overrun by Muslim immigrants have been traced to operators based in Sri Lanka, Vietnam, the Maldives, and other countries far removed from Britain, according to a BBC Panorama investigation. The accounts — some of which have amassed tens of millions of views — produce fabricated footage of dystopian future British cities and fake news segments, with creators motivated either by social media advertising revenue or, in some cases, alleged ties to hostile states such as Russia and Iran. London Mayor Sadiq Khan warned that the content is damaging the city's international reputation and called on platforms like Meta (which owns Facebook and Instagram) to label AI-generated material more clearly and stop algorithmically rewarding divisive posts.
