The arrests follow a known member of the far-right being detained on suspicion of plotting to assassinate Macron last year.
Six people have been arrested over an alleged far-right plot to attack Emmanuel Macron.
French security services arrested the men - who have yet to be identified - over a "loose plan" for “violent action” against the French president, according to officials.
The group were captured by anti-terrorism units in three areas of the country: the eastern French regions of Moselle and Isère and the north-west region of Ille-et-Vilain.
French TV channel BFM TV reports that the suspects are aged between 20 and 60 and that the man “considered to be main suspect” was found with a 44-calibre gun.
Last July, a far-right agitator was arrested for on suspicion of plotting to assassinate Macron.
The centrist president has recently addressed concerns over the rise of the far-right across Europe, including in France where the National Front's Marine Le Pen captured 10 million votes in the 2017 presidential election.
"We need to hear the fear and anger. There's anger against a Europe that has become too ultra-liberal," Macron told France's Europe 1 radio station. "This anger is directed at an ultra-liberal Europe which no longer allows our middle classes to live decently."
