I wonder if this is the work of arson/terrorism vs. something more mundane, like an electrical fire (things often go wrong when retrofitting old buildings for electric lighting).
The house across the street from a family member burned down a few months ago during renovations. But this has all the hallmarks of terrorist arson coming so soon after the NZ mosque attack. And muslims in France are well known for their car burnings.
Have any Muslims taken credit for it yet? What’s the point if they don’t admit that they did it?
