The deputy mayor of Paris, Emmanuel Gregoire, said the cathedral had suffered "colossal damages", and the emergency services were trying to salvage the art and other priceless pieces stored in the cathedral. A cathedral spokesman said the entire wooden interior was burning and likely to be destroyed.
Sounds like the whole thing may go up in flames. There's a reason for modern building codes. A structure made entirely out of wood, is a huge bonfire, waiting to happen. Thankfully, at this time, there are no reported deaths.
