Any decision in relation to the continued detention, transfer or prosecution of detainees is ultimately a matter for authorities under whose jurisdiction the individuals are detained. The British Government is clear that those individuals who have fought for, or supported Daesh, whatever their nationality, should face justice through a fair trial in the most appropriate jurisdiction. The UK will work with international partners, as well as partners in the region who can assist in establishing an appropriate pathway to justice within their territory or legal systems. Any internationally-supported justice mechanism must respect human rights and the rule of law as well as ensure fair trials and due process.
The UK has significant human rights concerns about trials of Daesh-related suspects in domestic courts of Iraq and regime-held areas of Syria including the use of the death penalty, which the UK opposes in all circumstances, as a matter of principle.
