Marches have been banned around Notre-Dame cathedral in central Paris, which was seriously damaged by fire on Monday. Just one march from Saint Denis, a town just north of Paris, to Jussieu University in the southern Paris, has been authorized.
The yellow vests started their protests after the Macron government planned to raise fuel taxes last year, then expanded into lower taxes and more government services.

Macron was slated to speak about his policies on Monday, but canceled the speech due to the Notre-Dame catastrophe. He has not set a new date for his announcement.
