Atal shared the video on Instagram, where he has 3.2 million followers, five days after Hamas' October 7 attack on a music festival and kibbutzim in southern Israel.
He took the post down the following day and apologised in an Instagram story, saying: “I want to clarify my point of view without any ambiguity: I strongly denounce all forms of violence, wherever in the world, and I support all victims.”
The 27-year-old defender apologised again during the court hearings, insisting that he had wanted to send a "message of peace". Atal also admitted that he did not watch the entire 35-second video before sharing it on his Instagram account.
But prosecutors and plaintiffs, namely Jewish organisations and the Professional Football League (LFP), were not swayed by this justification.
"Sharing a video means being party to its message and lending it visibility,” prosecutor Meggi Choutia said in court. "There is no talk of peace at any moment in these 35 seconds.”
Atal has been suspended by the Nice football club “until further notice”, and he received a seven-match ban – which has since expired - from the LFP.
However, the defender has received support in his home country, appearing for Algeria’s national football team three times, and is set to be included in their squad for the Africa Cup of Nations tournament this month.
