The Hind Rajab Foundation (HRF) said on Monday it had filed an urgent criminal complaint with Belgium’s Federal Prosecutor against an Israeli soldier it alleges was identified at the Tomorrowland music festival.
According to the legal advocacy group, the complaint relates to alleged war crimes committed during Israeli military operations in the Gaza Strip between 2023 and 2024.
The HRF said the suspect is believed to still be in Belgium and urged prosecutors to take immediate steps to prevent the individual from leaving the country while judicial authorities examine the case.
The organisation requested that the federal prosecutor refer the matter without delay to an examining judge and initiate the necessary investigative and preventive measures.
The foundation argued that the suspect’s presence in Belgium provides a legal basis for an investigation under Article 14/10 of the Belgian Code of Criminal Procedure, which allows Belgian authorities to examine alleged international crimes committed abroad under certain circumstances.
According to the HRF, evidence it gathered indicates the suspect served in an Israeli military unit deployed in Gaza City and Rafah between October 2023 and November 2024.
The group alleged that civilian infrastructure, including residential buildings, commercial properties, public offices and educational institutions, was systematically destroyed during the operations using armoured vehicles, military bulldozers and controlled demolitions.
It said it had submitted evidence concerning the suspect’s military service, deployment history, unit affiliation and alleged connection to the operations described in the complaint.
The foundation also referred to a previous case involving the Tomorrowland festival, stating that in July 2025, it and the Global Legal Action Network (GLAN) filed a complaint in Belgium against two Israeli soldiers attending the event. According to the HRF, Belgian federal police detained and questioned the two individuals before releasing them.
The allegations made by the Hind Rajab Foundation have not been independently verified, and Belgian authorities have not publicly announced any charges in the latest case.
