The next step was establishing how the edifice’s structure fared in the fire, Laurent Nunez, state secretary in the Interior Ministry told French broadcaster BFM TV.

Architects and experts are to discuss how firefighters are to proceed Tuesday morning and whether the cathedral is stable, Nenuz added.

Some 100 firefighters were still on the scene Tuesday morning.
