A deepfake video falsely depicted a France 24 journalist making statements about the safety of the Seine River water went viral, raising concerns about the cleanliness of the water and serving as a reminder of the potential dangers of deepfake technology and the importance of combating misinformation.

The falsified video claimed that France 24 journalist Catalina Marchant de Abreu had investigated the safety of Paris' water system just weeks before the French capital was set to host the 2024 Olympic Games and said that the Seine was "unsafe" - a statement later rebutted by France 24 as untrue.

The video depicted Marchant de Abreu supposedly collaborating with French and American microbiologists to examine the water quality in Parisian hotels. Marchant de Abreu is the host of France 24's Truth or Fake segment, where she investigates disinformation and fake news spread online. 

The deepfake was exposed account on X/Twitter and attributed to a Russian propaganda campaign designed to undermine the credibility of the Olympic Games in Paris. 

The deepfake raised concerns about the spread of misinformation, especially regarding public health and safety, and its potential to undermine public trust in legitimate news sources and create confusion.
