Three teenage British girls suspected of traveling to Syria to join the Islamic State terrorist group have appeared on surveillance video in Turkey.
Turkish media reports said the images show the teens boarding a bus in Istanbul. It is the first reported sighting of the girls since they left London almost two weeks ago.
Authorities have said they have no reason to believe the girls are still in Turkey, and believe they have crossed into neighboring Syria, parts of which have been taken over by the Islamist terror group.
The three east London classmates -- Shamima Begum, 15; Kadiza Sultana, 16, and Amira Abase, 15, boarded a Turkish Airlines plane from London's Gatwick Airport to Istanbul on February 17.
The two-minute video purportedly shows the three girls walking in and out of three separate bus operator offices over a period of 17 hours on February 17 and February 18 at the terminal in Istanbul's Esenler district.
Security officials say at least 500 Britons have travelled to Syria to fight with extremists, often via Turkey.
