Nizar ben Abdelaziz Trabelsi (born 2 July 1970) is a Tunisian former professional footballer. In 2003, a Belgian court convicted and sentenced Trabelsi to ten years' imprisonment for his association with Al-Qaeda, and for a variety of crimes, including attempting to destroy the military base Kleine Brogel Air Base.

Football career

Considered a talent of Tunisian football, Trabelsi started his career at his hometown club CS Sfaxien.

Trabelsi then moved to Germany to play for Fortuna Düsseldorf, however Fortuna quickly deemed him to be unsuitable for professional football. Shortly afterwards, he disappeared from football altogether. He was said to be the designated suicide bomber, and was to wear a business suit to conceal the strapped bomb onto himself before walking into the embassy.

Trabelsi was arrested in an apartment, in Uccle near Brussels, Belgium on 13 September 2001.

Conviction

In 2003, Trabelsi was sentenced to a ten-year prison term in Belgium, He was also found guilty of illegal weapons possession and being a member in a private militia. On 3 October 2013, he was extradited to the United States.

The United States had requested that Belgium extradite Trabelsi, given that American military personnel were present at the base. Trabelsi challenged that request in Belgium, contending that his extradition would violate the Extradition Treaty Between the United States of America and the Kingdom of Belgium of 1987. Belgium disagreed and extradited Trabelsi to the United States.

In September 2014, the European Court of Human Rights found that his deportation was performed in violation of Article 3 of the European Convention on Human Rights and ordered Belgium to pay 60,000 euros in damages to Trabelsi.

Trabelsi was extradited to the United States in October 2013, after he completed his sentence in Belgium. On 14 July 2023, he was found not guilty in an American federal court.

  • Immigration status: Following his acquittal, the U.S. government did not treat Trabelsi as a "free man" but as a foreign national subject to immigration law. He was considered an "ineligible applicant for admission" and was placed in immigration detention, remaining there for more than two years.
  • Failed criminal case, not civil violation: The acquittal by the federal jury meant the government failed to prove his guilt in the criminal case. However, this does not automatically lead to a finding that the government committed a civil violation that would require financial compensation.
  • Unlawful detention lawsuit: After his acquittal, Trabelsi filed a lawsuit against the U.S. government with support from the American Civil Liberties Union (ACLU). However, this lawsuit focused on challenging the legality of his continued detention, citing violations of immigration law and the U.S.-Belgium extradition treaty, rather than seeking financial damages for his unjust imprisonment. The U.S. District Court for the Eastern District of Virginia later ruled it did not have jurisdiction over his immigration detention.

As a consequence of these rulings, national courts in Brussels have demanded for Trabelsi to be extradited back to Belgium, with a penalty for the federal government of Belgium of up to €200.000 if this demand is not met.

Despite being acquitted, Trabelsi remained in a US prison until 2025, when the American Civil Liberties Union (ACLU) challenges the legality of Trabelsi's detention, citing violations of the U.S.-Belgium Extradition Treaty, U.S. immigration law, and the U.S. Constitution. He returned to Belgium on August 8, 2025 and was freed on October 22, 2025 by the Belgian federal authorities after an unsuccessful bid by the government to extradite him to Tunisia, his country of origin, which was rejected on humanitarian grounds by the Council chamber of Brussels and the Council for Alien Law Litigation, an independent administrative court. His lawyer declared to the press on that day: "My client has no ill will towards the Belgian society and simply wants a chance to build his life again, and return to Tunisia one day, but not before ensuring that he won't be arrested and tortured by the Tunisian authorities."
