Paris is burning

And their revolution is not televised as they announced it in their famous song....
I don't think it has anything to do with Muslims given the hour when it happened and how clumpsy they're when they try to make a terrorist attack like the one near Notre Dame a few years ago.
Seems the investigation has halted. Could it be there may have been some Muslims on the work restoration crew?
Cause of the fire? A careless candle or Allhu Akbar?
