Four people arrested and linked to the French extreme right were on Saturday charged over a suspected plot to attack President Emmanuel Macron during World War I remembrance ceremonies.
The four men aged between 22 and 62 appeared before an anti-terrorism judge in Paris and were charged with associating with terrorists and arms possession.
They were arrested on Tuesday after one man, living in southeastern France and armed with a knife, travelled to Moselle, eastern France, where he met with three other suspects.
At the time, Macron was touring nearby World War I battlefields and meeting with local people.
The French president will be hosting world leaders today to mark the 100th anniversary of Armistice Day, which marked the end of World War I.
