The Louvre Museum in Paris closed due to a brazen heist where thieves stole eight valuable items of jewelry in broad daylight. The theft occurred shortly after opening, with the thieves using power tools and a mechanical lift to access the museum. They threatened guards, stole from display cases, and attempted to set fire to their vehicle. Culture Minister Rachida Dati described the thieves as experienced and the incident as professional, with no injuries reported. Investigators are searching for suspects and reviewing CCTV footage.
