Selected to compete at the 2020 Summer Games in the -73 kg weight class, Nourine and his coach Amar Benikhlef announced his withdrawal following the conclusion of the draw of competitors. Nourine was quoted as saying his political support for the Palestinian cause made it impossible for him to compete against an israeli like Tohar Butbul, the 5 seed in the tournament, who he was drawn to potentially face in the second round, had he won in the first round.

The International Judo Federation announced his and his coach's immediate suspensions on 24 July 2021, pending a further investigation, and sent Nourine and his coach back home to Algeria from Tokyo.

The Federation explained: “According to the IJF rules, in line with the Olympic Charter and especially with rule 50.2 that provides for the protection of the neutrality of sport at the Olympic Games and the neutrality of the Games themselves, which states that 'no kind of demonstration or political, religious or racial propaganda is permitted in any Olympic sites, venues or other areas,' Fethi Nourine and Amar Benikhlef are now suspended and will face a decision by the IJF Disciplinary Commission, as well as disciplinary sanctions by the National Olympic Committee of Algeria back in their country.'“

It continued: “Judo sport is based on a strong moral code, including respect and friendship, to foster solidarity and we will not tolerate any discrimination, as it goes against the core values and principles of our sport.” (ILKHA)
