A fire has broken out at iconic Paris cathedral Notre-Dame.

Renovation work is underway at the 850-year-old building, but the cause of the fire is not yet clear.

Images on social media show smoke coming from the cathedral, a major tourist destination in the French capital.

Areas around the cathedral have been cleared of visitors as a major emergency operation takes place to tackle the blaze.

The mayor of Paris, Anne Hidalgo, described it as a “terrible fire”.

In 2018, the Catholic Church in France launched an appeal for funds to save the cathedral, which was starting to crumble.
