CNN just said the fire is across the street from the museum.
I hope so. However, we've also been told that none of the artifacts from Tutankhamun's tomb were damaged, yet the short security video from the museum clearly shows that both the exquisite statue of Tutankhamun standing in the boat with the harpoon and rope, and the one of him standing on the leopard, were shattered. Clearly recognizable pieces of those statues are on the floor.
Given that the security video shows only a small portion of the cases and the floor, it may be that many of the Tutankhamun treasures have already been damaged - or that this fire may be in the museum.
