French Anti-Terror Prosecutor Investigates Torture Allegations After Gaza Flotilla

Paris – 21 July 2026: France’s anti-terror prosecutor’s office, PNAT, has opened a preliminary investigation into alleged torture in the treatment of two French participants in a Gaza flotilla. The proceedings were opened on 1 July 2026 following complaints by those affected. One of the complainants is Marie Mesmeur, a member of parliament for the left-wing La France insoumise party from the Ille-et-Vilaine department.

The investigation concerns the period from 1 to 7 October 2025. According to the prosecutor’s office, it is examining allegations of torture as defined under the United Nations Convention against Torture of 10 December 1984. The Central Office for Combating Crimes against Humanity has been tasked with the inquiry. The opening of proceedings does not constitute a finding that the alleged acts occurred.

According to Mesmeur, the ship on which she was travelling was stopped by Israeli authorities. She says she was then taken to Israel and detained there for four days, after having spent nearly 24 hours under control on the boat. The lawmaker accuses guards of beatings, inadequate access to water, food and medical care, as well as degrading detention conditions. She states that she was unable to work for ten days because of an injured rib and bruising.

Israeli military and prison authorities have rejected the allegations. The proceedings in Paris will therefore primarily have to establish whether the complainants’ statements and medical information can be substantiated, which individuals were directly responsible, and whether a chain of command can be reconstructed. According to sources close to the complainants, the complaints also refer to political and administrative responsibility in Israel.

This is a second, legally separate PNAT investigation connected to Gaza flotillas. In early June 2026, the authority had already opened an investigation into alleged torture and war crimes following a notification from the French Foreign Ministry. That case concerned the treatment of French participants in another flotilla intercepted in May 2026. The chronological and factual separation of the two case files is significant for the criminal-law assessment.

Following the May incident, the French government organized consular assistance for the affected citizens. At the same time, the Foreign Ministry said it strongly advised French nationals against travelling to Israel and the Palestinian territories because of the regional security situation and the fighting in the Gaza Strip. The case thus combines two dimensions: France’s duty to provide consular protection to its own citizens and the criminal-law examination of serious allegations against foreign officials.
