Undesirable but Unremovable Migrants - War Criminals, Terrorists and Foreign Offenders in Limbo

Alleged 'criminal' migrants who find themselves trapped, unwanted in the countries hosting them but unable to be deported, are reffered to as Undesirable But Unremovable migrants (UBUs). This book traces the emergence of UBUs, shows how their numbers have increased over time, and reveals the inability of states to develop policy responses.
