lashes broke out between demonstrators and police in Paris on Saturday, April 20, during the weekly 'yellow vest' protests. Authorities had warned that rioters returning to the French capital could spark a new wave of violence. French police said they arrested more than 100 "yellow vest" demonstrators on Saturday in Paris as thousands of protestors took to the streets for a 23rd week of anti-government marches. AFP journalists reported scuffles between police and protesters in the afternoon, after hours of calm, as police used anti-riot grenades and tear gas to disperse marchers in the center of the French capital. Police headquarters reported 126 arrests and 11,000 checks on individual protesters.
