Iraq refuses to hand back Islamic State suspects it took from Syrian detention, its security adviser says

Al-Aboudi spoke to the AP on Wednesday 7 October, after a meeting between the two governments, and said Iraq had turned down Syria’s request to repatriate the thousands of suspected Islamic State members moved from Syrian detention centres into Iraqi custody earlier this year. He said about 400 of those held had been determined not to be ISIS members and could be released, that roughly 50 had already been repatriated, and that investigations continue, with anyone proven to have committed crimes in Iraq to be dealt with in Iraq. The wider figure carried in aggregations of the AP report is some 4,000 detainees. Every number here is the national security adviser’s own, given to a wire; none has been independently audited, and no Syrian response was in the material available to this desk.

Assessment: The detainee file is the quiet half of the coalition’s departure. Washington spent years looking for a state willing to take custody of the Syrian camps' Iraqi-linked population; Baghdad has now taken a large share and is declining to give any of it back, which converts a counterterrorism problem into a sovereignty asset and a lever over Damascus. Read the 400 figure as a political instrument as much as a judicial finding: releases are the mechanism by which Iraq demonstrates due process to an international audience without conceding the principle. The number to watch is not 4,000 but whether any independent body — the UN, the ICRC, Syria itself — ever confirms it.
