To ask Her Majesty's Government how many Daesh fighters are known to have returned to the UK; how many such fighters and individuals assisting Daesh in different capacities have been prosecuted in the UK courts, including anyone who has (1) financed, or (2) recruited for, Daesh; on what charges any such individuals have been prosecuted; and what progress they have made on the proposal to establish an international ad-hoc tribunal for Daesh.
Around 900 people have travelled from the UK to engage with the conflict in Syria and Iraq, against the advice of the Foreign Office. Of these, approximately 20% have been killed in the conflict and around 40% have returned to the UK.
The Governments priority is the safety and security of the people who live here. All of those who have returned, have been investigated and the majority have been assessed to pose no, or a low security risk. Around 40 individuals have been convicted on their return from Syria/Iraq, either because of offences committed overseas or for other activity linked to their involvement in terrorism. Individuals can be convicted in UK courts of offences committed overseas (including preparation of terrorism, encouragement of terrorism and membership of a proscribed organisation). Furthermore, through the Counter-Terrorism and Border Security Act 2019, we have extended this to new offences including: inviting or recklessly expressing support for a proscribed organisation and for sharing their propaganda.
The UK continues to work with international partners, as well as partners in the region in seeking to secure the prosecution of individuals who have committed crimes in the name of Daesh. Any such justice mechanism must respect human rights and the rule of law.
