The Kurdish-led armed force in northeast Syria should ensure the humane treatment of all men and boys it has evacuated or recaptured from a prison that the Islamic State (ISIS) assaulted and held for several days, Human Rights Watch said today. The regional fighters and US and UK forces supporting them should assess whether their forces complied with the laws of war during operations to recapture the prison and take all feasible measures to protect civilians during operations to find ISIS members and escaped detainees.
