For years the Canadian government has avoided the question of what to do with returning ISIS fighters and their families. As many as 5,000 alleged ISIS fighters and their families are being held in makeshift prisons in Syria. The number is swelling daily as ISIS loses its final strongholds in eastern Syria. As many as 32 Canadians are currently held by the U.S-backed Syrian Democratic Forces, a Kurdish-led group that’s been fighting ISIS. Some of the Canadians in custody were captured in battle. Others include two women believed to be from Ontario and Alberta, who surrendered to the SDF along with their children last week after fleeing one of the last ISIS-controlled villages in Syria. if suspected militants are returned to Canada, prosecuting them for their actions overseas presents significant challenges.
