The three men, taken to Syria by their parents at the age of 11 or 12, were allegedly forced to participate in propaganda activities, policing duties and combat roles under Islamic State, according to legal filings submitted in France.

A source familiar with the case said the detainees are seeking recognition as victims of a war crime due to their recruitment as minors.Their lawyers, Marie Dose and Matthieu Bagard, said in a joint statement that the French authorities were failing to uphold obligations under international conventions prohibiting the use of child soldiers.

They argued that the men’s transfer to Iraq and continued detention amounted to inhumane treatment rather than victim protection.The detainees are among approximately 5,700 suspected Islamic State fighters of multiple nationalities transferred from Syria to Iraqi custody earlier this year, following shifts in territorial control in northern Syria.

France has opened investigations into the three men for alleged terrorism-related offenses committed during their time in Syria.The lawyers contend that, instead of pursuing prosecution, French authorities should prioritize repatriation and rehabilitation, citing the circumstances under which the individuals were recruited and their age at the time.

Hundreds of French citizens joined the Islamic State after it seized large areas of Iraq and Syria in 2014 and declared a so-called caliphate. Iraqi authorities, supported by a U.S.-led coalition, declared victory over the group in 2017, while Kurdish-led forces in Syria defeated its remaining strongholds in 2019.

Since then, thousands of suspected fighters and their families have been held in detention facilities across Syria and Iraq. Kurdish authorities in Syria have repeatedly called on foreign governments to repatriate their nationals, but most Western countries, including France, have proceeded cautiously, often handling returns on a case-by-case basis.

The recent transfer of detainees to Iraq has renewed scrutiny over their legal status and future, particularly in cases involving individuals recruited as minors.
