The noble Lord raises a very important question. Of course, if British people who go to Syria return, they face the full force of the law as to why they travelled to that country when the Government had given every advice against doing so. The noble Lord will know of many cases where citizens return. However, to go into a war zone and retrieve someone is beyond what the Home Secretary is willing to do. Of course, the other point is that the Government put a huge amount of money into the region in humanitarian assistance, but the Home Secretary has rightly said that he will not risk the lives of British officials to go to retrieve foreign fighters—or, indeed, the children they have brought with them.
