Are there any serious politicians calling for the prisoners to be repatriated? Alistair Burt (Ex Foreign Office minister for the Middle East) this morning cautiously suggested that children of FTFs could be brought back to the UK if it could be proved they were British (only, ie not dual national) and that there was a means to bring them back, bearing in mind it's a conflict zone and there is no British diplomatic nor consular representation there. This was after the BBC found three very young children - apparently orphans - in a prison camp, allegedly from East London.They are free to travel to Syria and help look after the prisoners if they feel that strongly.
From a practical perspective, proving nationality of these children will be difficult, as will be getting them lawfully to the UK. Nothing to see, move along.
