Paris police chief Michel Delpuech said authorities are on watch for "violent groups" infiltrating the protests, and that riot officers will protect landmarks such as the Arc de Triomphe and the presidential palace, reports Reuters.

"We need to be prepared for worst-case scenarios," Delpuech told RTL radio, who added that he doesn't expect businesses in the capital to suffer the same level of disruption as they

ve over the past three weeks, when major stores and hotels suffered a dramatic drop in business as tourists avoided the area. 

This weekend's Yellow Vest protests, nicknamed "Acte V" - mark the fifth week of anti-government outrage which began over opposition to an announced fuel-tax designed to pay for climate change policies. 

Interior Minister Christophe Castaner said it was time for the Yellow Vests to tone down their protests and acknowledge that they had achieved their goals after French President Emmanuel Macron rolled out a series of economic and tax incentives, including a minimum wage hike, no tax on overtime pay, tax-free year-end bonuses, and a six month delay to the fuel tax.
