PARIS—Thieves in balaclavas broke into Paris’ Louvre museum on Sunday, using a crane to smash an upstairs window, then stealing priceless objects from an area that houses the French crown jewels before escaping on motorbikes, officials said.
The robbery raises awkward questions about security at the museum, where officials had already sounded the alarm about lack of investment at a world-famous site, home to artworks such as the Mona Lisa, that welcomed 8.7 million visitors in 2024.
