A fire at the cathedral in the French city of Nantes is believed to have been started deliberately, prosecutors say.

Axar.az reports citing foreign media.

Three fires were started at the site and an investigation into suspected arson is under way, Prosecutor Pierre Sennes said.

The blaze destroyed stained glass windows and the grand organ at the Saint-Pierre-et-Saint-Paul cathedral, which dates from the 15th Century.

It comes a year after the devastating fire at Notre-Dame cathedral in Paris.

But the local fire chief said the fire in Nantes had been contained and was "not a Notre-Dame scenario".
