A massive fire has consumed the 19th century basilica of Saint- Donatien in the French city of Nantes.
The blaze broke out after morning mass, according to Rev Benoit Bertrand, and clergy were evacuated from the house of worship.
Firefighters are continuing to battle the blaze.
It is feared that the basilica has sustained significant structural damage.
What caused the fire has yet to be established, but local media is reporting that welding work going on within the church may be behind the destruction.
