The families of three British teenagers who are believed to have fled to Syria to join Islamic State have travelled to Turkey in a bid to trace the girls.
ITV News joined relatives of Shamima Begum, 15, Kadiza Sultana, 16, and 15-year-old Amira Abase, as they travelled to the country to follow the girls' last known movements before they are thought to have crossed the border into Syria.
They hope to find clues that may help them find or even contact their daughters.
The three girls travelled to Istanbul last month before reportedly crossing the border into Syria.
Renu Begum, Shamima's sister, said: "This is our next step, just trying to get the message out to them that we've followed them all the way out here and we just want them to know that we love them"
Halima Khanom, sister of Kadiza Sultana, said: "I don't really recognise my sister in the video, the CCTV that we saw because this is just not her and i just want to understand her, to find some answers and get some help".
They along with Abase Hussein, Amira's father, visited the coach station where CCTV footage captured the girls waiting for their bus to the Syrian border in February.
Staff at the coach station told them: "They were smiling as they arrived and smiling as they left."
