Some Olympique de Marseille fans stormed into the team's training ground hours before a Ligue 1 game against Stade Rennais as they protested against the club's officials, with Saturday's fixture subsequently postponed.
RMC Sport reported some 150-200 supporters tried to break into the Robert Louis Dreyfus centre.
Footage on RMC Sport's twitter feed showed some of the fans forcing their way in. Some were seen throwing flares and lighting firecrackers.

WATCH: Footage of Marseille fans storming training ground

The outlet published footage of fans marching in the streets and carrying banners reading "(Club) directors, out", as well as others directly targeting OM president Jacques-Henri Eyraud.
It then reported the situation had calmed down, without elaborating. OM were not immediately available for comment.
Earlier in the day, St Étienne's training session was interrupted by 300 supporters who came to apply pressure to the team following their humiliating 5-0 derby defeat to Lyon ahead of their clash against OGC Nice on Sunday.
