Question to the Home Office:

To ask the Secretary of State for the Home Department, what assessment her Department has made of the number of people aged under 18 who travelled to parts of Syria and Iraq controlled by IS/Daesh in each of the last two years.

We believe approximately 800 UK linked individuals of national security concern have travelled to take part in the Syrian conflict since it began. Of those who are known to have travelled, about half have returned. This number will include some individuals who were under 18 at the point of travel.
