France protests:

Paris authorities opened an investigation Sunday into anti-Semitic remarks hurled at a noted philosopher during a “yellow vest” protest in the capital, an incident that raised national concerns about the movement’s ascendant radical fringe. A few demonstrators targeted Alain Finkielkraut with insults on the sidelines of a yellow vest protest through Paris on Saturday. The incident prompted criticism from French President Emmanuel Macron and other prominent figures. The increasingly divided movement has held protests every Saturday since mid-November.
