During a visit to a town in southern France on Tuesday, French President Emmanuel Macron was smacked in the face by a guy amid a crowd of onlookers, according to video of the incident.
Macron's security team rushed in to bring the man to the ground and take him away from Macron.
According to broadcasters BFM TV and RMC radio, two people were arrested in connection with the event.
The incident, according to French Prime Minister Jean Castex, was an affront to democracy.
The event occurred during Macron's visit to the Drome region of southeastern France, where he met with restaurateurs and students to discuss how life is returning to normal following the Covid-19 outbreak.
Macron, clothed in shirt sleeves, could be seen walking towards a crowd of well-wishers who were behind a metal fence in a video circulating on social media.
