On the ground in Paris, some 400 firefighters have been mobilised to tackle the flames which have spread across the Cathedral's roof, bringing down its spire.

Prime Minister Theresa May, currently in Wales, said: "My thoughts are with the people of France tonight and with the emergency services who are fighting the terrible blaze at Notre-Dame cathedral."

Foreign Secretary Jeremy Hunt, in Japan, said he was thinking of his French counterpart Jean-Yves Le Drian "and all our friends in France tonight following the devastating fire at Notre Dame.

"Heartbreaking for the millions who love this great cathedral and great city across the world. Wishing you all the best in tackling the blaze and its consequences," he added.
