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."

Seven people have been arrested in the investigation of a stunning heist at the Louvre Museum in Paris, but the lavish, stolen jewels that once adorned France’s royals are still missing.

The crew of thieves used a basket lift to scale the Louvre’s façade, forced open a window, smashed display cases and fled, according to French officials.
