French President Emmanuel Macron called the crime "an attack on a heritage that we cherish because it is our history," and vowed that "the perpetrators will be brought to justice."

The Louvre reopened Wednesday morning, three days after thieves forced open a window and stole French crown jewels in a daring, daylight raid on the musuem.

Laurence des Cars, the head of the Louvre, is expected to be grilled by French senators about the robbery at a hearing later on Wednesday.
