France moves to high terror alert level, evacuates iconic The Louvre over threat

France elevated to a higher terror alert Saturday and evacuated the iconic The Louvre Museum in Paris — home to the Mona Lisa painting — as new threats emerged in the aftermath of a known extremist’s fatal stabbing of a teacher at a school.

The museum said it had emptied the building and closed for the day after receiving a written warning, but it reported no injuries or incidents. Police were seen sweeping the building as tourists streamed out.

France raised its terror threat alert level and deployed 7,000 troops after Friday's school attack north of Paris. Authorities and witnesses alleged the suspect shouted "Allahu Akbar!" before killing the teacher.
