"The club understands the frustration generated by the succession of poor performances and performances far removed from its values," Nice said in a statement.
"However, the incidents that occurred during this gathering are unacceptable. Several club members were targeted. OGC Nice offers them its full support and condemns these acts in the strongest possible terms."
