At least 1,600 Britons have travelled to the Syrian and Iraqi battlefields, more than double the number previously reported, foreign intelligence officials have claimed.
About 500 of these have returned to the UK, three well-placed foreign intelligence officials have told The Sunday Times.
“We believe that even 1,600 is a very conservative estimate because by the time we started picking up on the scale of [the] problem, a lot of the people had slipped through the gates,” said one official. “And we’re still seeing at least about five people leaving the UK for Syria and Iraq every week — and that’s not to count the ones we don’t know about.
I would not be at all surprised to hear that the number of “Canadian Jihadis” has been understated as well.
