The Louvre Museum in Paris has been forced to close while police investigate a brazen heist which reportedly targeted France's priceless crown jewels.
Thieves wielding power tools broke into the world's most visited museum in broad daylight, before escaping on scooters with items said to be of "incalculable" value.
Here is what we know about the crime which has stunned France.
The theft occurred on Sunday between 09:30 and 09:40 local time, shortly after the museum opened to visitors.
The thieves appear to have used a mechanical ladder to gain access to the Galerie d'Apollon (Gallery of Apollo) via a balcony close to the River Seine.
