The families of three missing east London schoolgirls who fled to join Islamic State militants in Syria have flown to Turkey to retrace their steps.
Shamima Begum, 15, Kadiza Sultana, 16, and Amira Abase, 15, all students at the Bethnal Green Academy, travelled to the war-torn country via Turkey last month.
There are fears they may have been persuaded to become so-called 'jihadi brides'.
Their families have followed the first half of their journey to Turkey in an attempt to trace them.
In a special report for ITV News, they were filmed speaking to staff at Istanbul coach station, where the teenagers waited for their bus to the Syrian border.
There they spoke to a man who unknowingly let the girls in. He said they were "smiling as they arrived" and "smiling as they left".
Renu Begum, sister of Shamima, told ITV News: "This is our next step basically to get the message out to them that we've followed them all the way out here. We want them to know that we love them."
Halima Khanom, sister of Kadiza, said: "I don't really recognise my sister, the video and the CCTV that we saw. Because this is just not her and we just want to understand her, you know, to find some answers and get some help."
Abase Hussein, father of Amira, said: "I don't know how to explain. I can't describe my feelings. I feel like my girl is next to me when I find someone that's on their last journey who saw them. I feel like my daughter is next to me - that's the feelings I have."
The families left through the same door the girls did during their long wait at the bus station, and family lawyer Tasnime Akunjee told ITV News: "Of course they feel responsible for their own children, that goes without saying.
"But the fact is these girls were school children and much of what took place clearly took place at school. Police put a cap on information that they and the school were giving back to the parents."
