The first photos shown of the interior of Notre Dame cathedral after a massive fire broke out Monday seem to show the central part intact, with the roof and vault taking the worst of the damage.

The pictures show smoke in the area round the altar, and a massive hole in the roof.

No official estimates of the damage have been released.
