My deepest sympathies to the people of Paris, France.
Don’t breathe the smoke; the roof of the building was solid lead.
This is a great tragedy for art and culture; I wonder what happened. I grew up scampering around that building, and I have no idea how many times I hauled myself up the stairs to the roof so I could see the city below, the clusters of tourists like ants.
According to The Guardian the fire was started by accident during maintenance/construction work.
