French unions and student groups are set to take to the streets for another day of protests on Saturday, while the Yellow Vests movement plans a separate rally in central Paris despite a ban by authorities. The demonstrations follow weeks of youth-led unrest and nationwide strikes that drew hundreds of thousands of workers protesting over the rising cost of living.Student groups and trade unions have called for an authorised march in central Paris "against the high cost of living and in support of young people".Yellow Vests activists, however, have refused to join, instead calling for a separate rally at Place de la Concorde, near the lower house of parliament and presidential palace, despite a ban by authorities, and called for "mass disobedience".
