The French civil security agency, Sécurité Civile, has responded to US President Donald Trump’s suggestion that “flying water tankers” should be used to fight the Notre Dame fire.

The agency tweeted, “The drop of water by air on this type of building could indeed result in the collapse of the entire structure.”

“The weight of the water and the intensity of the drop at low altitude could indeed weaken the structure of Notre-Dame and result in collateral damage to the buildings in the vicinity,” it said.

The civil security agency is part of the Interior Ministry.

Earlier today, Trump had said on Twitter, “Perhaps flying water tankers could be used to put it out. Must act quickly!”
