Piers Morgan, 53, took to Twitter and said: “Horrendous & heart-breaking.
“Few greater or more beautiful cultural monuments in the world than Notre-Dame Cathedral.
“Now engulfed in a raging inferno. Hope they can save it. #NotreDame.”
Retweeting another video on the awful scenes, he said: “Jeez. In Easter week, the famous spire of one of the great Catholic monuments falls. Awful to watch.”
Ellie Goulding said: “Feel profoundly sad about this… so much lost in a few seconds … I am praying (which I don’t do often) for the fire to be contained soon …. utterly heartbreaking.”
