THE SPRAWLING al-Hol camp in north-eastern Syria is part of a network of prisons holding tens of thousands of detainees and family members from Islamic State’s jihadist “caliphate”, which was smashed by America and its allies in 2019. Western securocrats have long worried that prisoners might break out and wreak bloody havoc, in Syria and abroad. Such fears have intensified given the turmoil after the fall of Syrian dictator, Bashar al-Assad, in December.
