The Sécurité Civile of France, part of the French Ministry of Interior, said in a tweet, “all means are being used, except for water-bombing aircrafts which, if used, could lead to the collapse of the entire structure of the cathedral.”

According to CBS News, authorities have not yet released the cause of the fire or any further information as to how the fight to suppress the flames has progressed.
