New CCTV footage has emerged which appears to show the British schoolgirls who travelled to Syria.
The video seems to show the girls waiting at a bus station in the Turkish capital Istanbul.
It comes as fears grow that London students Kadiza Sultana, Shamima Begum and Amira Abase had fled in a bid to become 'jihadi brides' for ISIS terrorists.
Counter terrorism police confirmed earlier this week that the three schoolgirls have crossed the border into Syria.
Since then, a diplomatic row has broken out between British and Turkish authorities on the details of how the schoolgirls travelled to the country without more thorough checks being carried out.
Officers from the MPS Counter Terrorism Command leading the investigation have said that they now have reason to believe that they are no longer in Turkey and have crossed into Syria.
