Thieves broke into the Louvre in Paris — the world's most visited museum — early Sunday morning. Museum officials said they stole jewelry and fled.

Paris Police Chief Patrice Faure informed the French Senate that ageing systems and slow implementation of necessary repairs had left the Louvre Museum with critical security vulnerabilities.

Days after eight pieces of the French crown jewels were stolen from the Louvre, a former bank robber who once toured the now-infamous Apollo Gallery for a Louvre podcast says he warned a museum official of weaknesses in security.
