Embattled French President Emmanuel Macron announced a series of financial measures seeking to defuse the "yellow vest" revolt that has triggered violent protests in cities across the country.

Paris was in lockdown early on Saturday with thousands of French security forces braced to meet renewed rioting by "yellow vest" protesters in the capital and other cities in a fourth weekend of confrontation over living costs.

France will close the Eiffel Tower and other tourism landmarks in Paris and draft in thousands more security forces on Saturday to stave off another wave of violent protests in the country over living costs.

Police yesterday fired tear gas and water cannon in central Paris against "yellow vest" protesters demanding French President Emmanuel Macron roll back tax hikes on motor fuel.
