PARIS (AP) — Paris is deploying thousands of police to protect landmarks and government buildings as yellow vest groups, unions and environmental activists plan a multitude of weekend protests.

Yellow vest organizer Thierry-Paul Valette told The Associated Press Friday that demonstrators hope their gathering Saturday in Paris and other cities could revive their flagging movement against economic injustice .

French President Emmanuel Macron addressed some yellow vest concerns earlier this year, but anger is mounting again over his plans to overhaul France's costly, convoluted pension system .

Hard-left union Workers' Force is holding a separate march against the retirement reform Saturday, amid concerns it will require people to work longer and reduce pensions.

Climate activists meanwhile are demonstrating Saturday in Paris to demand more action from the government and companies to reduce emissions and save the burning Amazon rainforest and the melting Arctic.
