The investigation into the Louvre Museum burglary has expanded internationally, focusing on a Belgian lead after analysis of Eastern European suspects' phones revealed connections to Belgium. French investigators are pursuing inquiries in Belgium while continuing efforts in France to identify all members of the criminal network. The thieves stole valuables worth 88 million euros, including items linked to historical figures, and none have been recovered yet. Some suspects may be willing to disclose the location of the stolen jewels to lessen their sentences.
