Nice supporters stormed the pitch and confronted the away team's midfield star Dimitri Payet at the score 1-0 in the 76th minute.
Before that, Payet had thrown back a plastic bottle in the audience that someone from the stands had thrown at him.
Before that, Payet had been subjected to bottle-throwing every time he hit a corner.
In connection with the turmoil on the pitch, the players were led off the pitch by the referees.
A moment later, the news came that the match would resume, but it was only Nice who stepped out on the field again.
Thus, the match could not be completed and the home team was awarded the victory with 3-0 in accordance with the league's rules.
According to the broadcasting company Amazon, Marseille is trying to get a replay instead, reports the German news agency DPA.
- The league has decided to continue.
We have decided, referring to the safety of our players who have been attacked, not to continue the match, said Marseille chairman Pablo Longoria.
Marseille trio Luan Peres, Mattéo Guendouzi and Payet are said to have been injured in the chaos.
Nice players Jean-Clair Todibo and Justin Kluivert are also said to have been subjected to violence by Marseille's security guards.
