US President Donald Trump commented on the massive fire that engulfed the Notre Dame Cathedral in Paris on Monday. Trump made the remarks while starting to speak at an event about the economy and tax reform in Minneapolis, Minnesota.

"They're having a terrible, terrible fire...it was it was burning at a level that you rarely see a fire burn. It's one of the great treasures of the world," Trump said, adding "it might be greater than almost any museum in the world and it's burning, very badly. Looks like it's burning to the ground."

Trump admitted that would likely "put a damper" on what they were about to speak about in Minneapolis, because "that is beyond countries, that's beyond anything that's a part of our growing up, it's a part of our culture, it's a part of our lives. It's a truly great cathedral. And I've been there and I've seen it and there's no cathedral, I think I could say this probably, no cathedral in the world like it it's a, it's a terrible scene."

"They think it was caused, by this moment, they don't know but they think it was caused by renovation. And I hope that's, the reason, renovation. You know what's that all about? But it's a terrible sight to behold," Trump concluded.

The spire and part of the roof of the Cathedral collapsed earlier in the evening on Monday, after the fire rapidly spread though the cathedral.

The cause of the blaze is not yet known.
