"The air drop on this type of building could indeed lead to the collapse of the entire structure," tweeted the Civil Security.

To drop water on Notre-Dame de Paris to extinguish the flames is not an option, said Monday evening the Directorate General of Civil Security, as it could destroy the building in the grip of a violent fire. "Our Lady: the air drop by air on this type of building could indeed lead to the collapse of the entire structure," tweeted the Civil Security Monday, while since the early evening, the flames ravage the cathedral, whose arrow has collapsed.

It is a "difficult fire". "It is so terrible to witness this gigantic fire at Notre-Dame de Paris, maybe we should use water bombers to extinguish it, we must act quickly", had quickly tweeted the American president Donald Trump. It is a "difficult fire", said the firefighters to AFP. About 400 of them are mobilized around the building, according to the Interior Ministry on Twitter.

On the spot, the helpers try to extinguish the fire with powerful water launcher, perched on articulated arms several tens of meters high, according to images of AFP. The fire, which spreads extremely fast, took in the attic of the cathedral, said firefighters. It seems to be part of scaffolding installed on the roof of the building, built between the twelfth and fourteenth century, according to firefighters. The fire triggered a wave of international excitement, and French President Emmanuel Macron canceled his televised speech after a big debate to get there.
