#1 included a number of Europeans, notably: an Irish woman and her daughter,4 at least one British woman and her two children,5 at least nine French women and about 25 children,6 at least three Belgian women and their children,7 and at least one German woman and one Swedish woman with their respective children.8 Some of these families managed to return to their home countries in the following months, via Turkey, while others are still unaccounted for. Except for the Ain Issa incident, however, the worst-case scenario of massive escapes from the detention facilities located near the Turkish border did not materialise. Given the context, this is nearly a small miracle. Indeed, following the Turkish offensive, Kurdish forces had redeployed part of their guards and staff away from securing detention facilities to defend the Kurdish territory, while insecurity was simultaneously rising in the camps and prisons as a result of internal revolts. Furthermore, ISIS pledges to free jihadi detainees had already increased the pressure on the Kurdish authorities.9 Concern among European intelligence services was very high in October 2019. If the worst could be avoided, the situation further deteriorated nonetheless. Over the past year, several mutinies have occurred in Kurdish detention facilities. For instance, on 29 March 2020, ISIS detainees managed to take control of part of the al-Sinaa prison, in northeast Syria’s town of Hasakah, where 5,000 ISIS male fighters are held, including a number of Europeans.10 The riot was quelled within 24 hours, but more riots broke out in the same prison in early May, in June and twice in September 2020, as well as a number of jailbreaks attempted. 1 1 No European male fighter has reportedly escaped from Kurdish prisons, but according to a report from the global coalition against ISIS, the “the risk of a mass breakout cannot be discounted��.12 Similarly, in camps for women and children, the security conditions have significantly deteriorated. This is notably the case in the infamous camp of al-Hol, where 65,000 women and children are being held,13 mostly Syrians and Iraqis – although that number will soon be drastically reduced as a result of the recent announcement by the Kurdish authorities that most of the 28,000 Syrian women and children in al-Hol would be released. 14 Security conditions have particularly worsened in the “annex” of the camp, where 10,000 “foreigners” from around 60 different nationalities are still being held.15 Cases of organised rebellion, violence among ISIS women and children, or power grab by extremist women trying to impose ISIS-style sharia law in the camp have been repeatedly reported.16 Similar incidents were already at play in 2019, but the situation clearly “became worse since the Turkish incursion”.17 A number of escapes of ISIS women and children have been reported in al-Hol. According to the Kurdish forces, more than 700 attempted escapes were prevented between March 2019 and September 2020, noting that these attempts have increased since October 2019.18 This significant number of (attempted) getaways highlight the growing importance of financing and smuggling networks that allow these women to raise funding and get support for their exfiltration, whose cost is estimated between $10,000 and $35,000. 19 A number of Europeans have managed to escape al-Hol under these conditions since October 2019, including: at least 4 Finnish women with children,20 at least 10 Dutch women with children,21 at least 10 French women with children,22 about 6-10 Swedish women with children,23 at least 4 Belgian women with children,24 at least 2 German women with EGMONT Royal Institute for International Relations 2
