Over 850 UK-linked individuals of national security concern travelled to engage with the conflict in Syria and Iraq. We estimate that over 15 percent of those who travelled have been killed in fighting in the region and just under half have returned to the UK. Anybody who does return will be investigated by the police to determine if they have committed criminal offences or pose a risk to national security. Those who travelled to, or remained in Syria or Iraq from 2014 are more likely to be a current national security concern than those who travelled and returned before then. While it would not be appropriate to provide a breakdown of the investigation status of travellers or returners, a significant proportion of those individuals who have already returned fall into the latter category and have been assessed as posing little or no national security concern.

The Government is committed to doing everything possible to protect our communities from the threat of terrorism. To respond to this threat, it is vital that we use all the means at our collective disposal to divert people away from terrorist activity, and we are exploring the best ways of doing this with our partners.

Where there is evidence someone has committed an offence they will be prosecuted accordingly. This is a decision for the Crown Prosecution Service. An increase in the number of people facing charges does not affect the threshold for prosecution.

We are a reviewing our counter terrorism strategy to make sure we respond to the evolving threat in the most effective way we can, both now and in the future. We engage closely with counter terrorism partners across the world, including sharing capabilities and experience in order to keep the public safe.

Approximately 850 UK linked individuals of national security concern have travelled to engage with the Syrian conflict. We estimate that just under half have returned and approximately 15% are now dead. This number includes all those of national security concern, not just those affiliated with Daesh. Everyone who returns from taking part in the conflict in Syria or Iraq must expect to be investigated by the police to determine if they have committed criminal offences, and to ensure that they do not pose a threat to our national security.
