A former Belgian soldier is helping European families bring home their children who have gone to fight in Syria.

Dimitri Bontinck persuaded his own son to leave the ranks of Isis militants and now he is helping others in the same situation.

Pol Van Hessche's 18-year-old son Lucas went to Syria with his best friend 19-year-old Abdelmalek Boutalliss.

Duncan Crawford joined him as he headed to the town of Kilis, next to the Syrian Turkish border.
