French Interior Minister Gerald Darmanin said he was launching a probe into clashes that broke out on Monday after police cleared out a new migrant camp in Paris' Place de la Republique.
People posted photos and videos on social media of police hitting demonstrators as they moved in to clear the square of migrants' tents, which the police said had been set up without official permission.
"Some of the images of the dispersion of the illegal migrant camp at Place de la Republique are shocking," Darmanin wrote on Twitter in the early hours of Tuesday, adding that he was seeking a full report into the incident.
The migrant camp at Place de la Republique emerged just a week after police had cleared out a bigger, illegal migrant campsite near the French national sports stadium.
