French President Emmanuel Macron has promised to rebuild Notre Dame Cathedral and says he is seeking international help to restore the Paris landmark.

Macron said after the French capital’s fire chief announced the emergency response had changed into a monitoring and mop-up operation, “The worst has been avoided although the battle is not yet totally won.”

Macron said a national fundraising campaign to restore Notre Dame would be launched Tuesday and he called on the world’s “greatest talents” to help.

The French leader credited the “courage” and “great professionalism” of firefighters with sparing Notre Dame’s facade and two landmark towers from being destroyed.
