French President Emmanuel Macron has canceled his planned speech to the nation because of the fire at Paris' Notre-Dame cathedral, noted an official at the president's Elysee office, Reuters reported.

The president had to sum up the results of the national debates, taking place in the country and announce the measures that the government will take in response to the “yellow vests” protests.

Other French politicians are shocked by the fire. Paris Mayor Anne Hidalgo said the fire brigade is trying to control a "terrible fire" that broke out at the cathedral, CNN reported.

"A terrible fire is underway at Notre-Dame Cathedral in Paris," Hidalgo said. "The fire brigade is trying to control the fire. We are mobilized locally in close connection with church authorities. I ask everyone to respect the security perimeter."
