Interior Minister Christophe Castaner said exceptional measures are being taken to try to save the cathedral.

“Support and solidarity with @PompiersParis (fire brigade) mobilized to save our common heritage, in the heart of Paris. An exceptional force was deployed by the @prefpolice (Paris police) to neutralize this violent fire. I share the immense emotion of the Parisians,” Castaner tweeted.

Former French President François Hollande ‏said on Twitter, “Notre Dame is our common heritage. It’s a wound to see it devastated by flames. Respects to the firemen trying to extinguish the fire.”
