British teenage girls Shamima Begun, Amira Abase and Kadiza Sultana (L-R) walk through security at Gatwick airport before they boarded a flight to Turkey on February 17, 2015, in this combination picture made from handout still images taken from CCTV and released by the Metropolitan Police on February 22, 2015. British police launched an appeal on Friday to trace the three London schoolgirls who are believed to be making their way to Syria, having flown to Turkey earlier this week. The three friends, two aged 15 and one 16, left their east London homes on Tuesday and travelled to Gatwick airport where they caught a Turkish Airlines flight to Istanbul without telling their families. Police said they were working with Turkish authorities to try to find the girls and bring them home. CCTV footage shot on February 17.
