Coalition forces are taking biometrics from IS fighters and collaborators in Raqqa to try and ensure they are trackable as fighting comes to a climax.U.S.-backed forces making their final push into the city of Raqqa are taking biometric details of Syrians who, for various reasons, had collaborated with or worked for the terror group.”What we did do with the SDF, is we did take all of those members and we enrolled them biometricaly, so that we are able to track them into the future,” Major General James Jarrard, commander of the special operations joint task force for Operation Inherent Resolve, told VoA this week.The collection of biometric information from those who fought for or worked with Islamic State in Raqqa is just a small part of a much wider effort encompassing other areas once under the terror group's control.The forces aim is to make sure those affiliated with IS are not able to go undetected and find ways to unleash terror and havoc, whether in Iraq and Syria or the West.The collected information commonly includes fingerprints, photos, DNA samples and even retinal scans, and not just from Syria. Iraqi forces and U.S.-backed Kurdish forces in Iraq have also been gathering biometric data.
