French authorities have discovered a neo-Nazi group that allegedly plotted to attack Jewish or Muslim places of worship, reported Agence France-Presse on Tuesday.

Five members of the cell, “close in ideology to the neo-Nazi movement,” were charged between September and May over the alleged plan, a source close to the investigation told AFP.

“The investigation suggested they were developing an ill-defined plot to carry out an attack, likely to target a place of worship,” said the source, without providing details of motives or specific targets.

In July 2017, a 23-year-old who had three kitchen knives discovered in his car, was charged with planning to assassinate French President Emmanuel Macron. He also admitted to wanting to murder “Muslims, Jews, blacks and homosexuals.”
