Malta sees surge in viral AI-generated video claiming ancient city discovered under Valletta, but experts say it's completely fake. A clip circulating on TikTok and Instagram shows what appears to be a massive underground Roman temple beneath the capital, with thousands of users sharing it as real. Archaeologists have confirmed the footage is created using computer-generated imagery, not actual ruins. The Malta Tourism Authority has issued a warning not to fall for the hoax, reminding visitors that while the country is rich in history, this specific discovery is fictional.
