This paper highlights the challenges for training professionals to enable gender-sensitive rehabilitation and reintegration interventions for children returning to Europe from the conflict zone in Iraq and Syria. The paper identifies the need for gender-sensitive training and responses based on a) the gendered experiences of children while in Iraq or Syria and b) the gender-blind provisions for their return to date. The paper also emphasises the importance of age-appropriate consideration based on age on arrival and departure and the length of time they spent in the conflict zone.
