Ligue 1 side Nice suspended Algerian international Youcef Atal "until further notice" on Wednesday after he shared a controversial post on social media linked to the conflict between Israel and the Palestinian Islamist movement Hamas.
Even though he quickly deleted the post and apologised, the club said in a press release that, given the "seriousness" of the post, it was taking immediate disciplinary action "prior to any action that may be taken by the sporting and legal authorities".
French prosecutors on Monday launched a preliminary investigation into Atal on suspicion of "glorifying terrorism".
