he Louvre remained closed Monday after historic jewels were stolen in a daring daylight heist. Thieves used a basket lift to access the museum, smashed display cases, and fled with Napoleonic jewels. The theft occurred Sunday, just 30 minutes after the museum opened. French Justice Minister Gerald Darmanin acknowledged security failures. Interior Minister Laurent Nunez ordered a reassessment of security measures at cultural sites. Investigators are working on evidence, including motorcycles found at the scene. Culture Minister Rachida Dati said the heist lasted less than eight minutes and was highly efficient.
