France has opened a France-Israel flotilla probe into alleged war crime and torture claims linked to the treatment of French activists detained during a Gaza-bound aid mission. The investigation was confirmed by the national counterterrorism prosecutor’s office on Friday, following a request from the government.
The case focuses on allegations made by activists who were detained by Israeli authorities after taking part in a humanitarian flotilla headed toward Gaza. The group was intercepted in international waters on May 18, when Israeli forces stopped multiple vessels carrying more than 430 activists from several countries.
According to officials, the French investigation is examining claims of mistreatment during detention. The probe includes accusations of “war crimes” and “torture” as described by returning activists. Authorities in France said they are reviewing testimony and evidence submitted by participants who returned to the country after the incident.
Israel has not accepted the allegations. The Israeli prison service said the claims of physical abuse, sexual harassment, and psychological violence are “entirely without factual basis.” Officials maintain that detainees were treated according to legal procedures.
Tensions increased after Israel’s far-right National Security Minister Itamar Ben Gvir posted a video showing detained activists. The footage sparked international criticism, with some observers calling the video humiliating and inappropriate. Following the incident, France imposed a travel ban on Ben Gvir, preventing him from entering the country.
Several French activists who took part in the flotilla described what they said was harsh treatment during detention. They claimed they were held in stressful conditions and subjected to degrading behavior. One activist alleged she was assaulted inside a dark holding container, while another described being forced into uncomfortable positions for long periods. These accounts have not been independently verified.
The France Israel flotilla probe also follows wider diplomatic concern over the interception of humanitarian vessels bound for Gaza. Activists say the mission aimed to deliver aid and draw attention to the humanitarian situation in the region. The flotilla included participants from multiple countries, and more than 30 French nationals were involved.
Some of the activists were released and returned to France on May 22. However, reports indicate that a small number of participants remained under medical care in Türkiye after their release. Officials have not released further details about their condition.
The United Nations has also weighed in on the incident. Francesca Albanese, a UN special rapporteur on the Palestinian territories, commented that the treatment of flotilla activists was comparatively less severe than conditions faced by Palestinians in Israeli detention facilities. Her remarks added to the international debate surrounding the case.
The French investigation marks a significant diplomatic step, as it is rare for a European country to open a war crime probe related to the treatment of its citizens by another state in this context. Legal experts say the outcome could depend on evidence gathered from testimonies, communications, and international cooperation.
The France Israel flotilla probe is expected to continue in the coming months as investigators collect statements from activists and review available documentation. French authorities have not confirmed whether the investigation could lead to formal charges or international legal action.
Diplomatic relations between France and Israel may face further pressure depending on the findings of the inquiry. The case has already drawn strong reactions from political figures, human rights groups, and international observers who are closely watching developments.
For now, the investigation remains ongoing, with officials stressing that all allegations will be carefully examined before any conclusions are reached.
