Some official context:
The number of people travelling to Syria from the UK is judged to be in the low hundreds and available information shows that the number of Syria-related arrests increased substantially in 2014. The figure for the whole of 2013 was approximately 25 yet for the first three months of 2014 alone it is approximately 40.

Since January five people from Birmingham have been charged with Syrian-related offences and are currently awaiting trial.
