Footage shows three missing British girls at Turkey bus station

Security footage appears to show three British schoolgirls, believed to be on their way to join Islamic State militants, waiting for hours at a bus station in Turkey before travelling to a city near the Syrian border, media reported.

British police and the girls’ families have issued appeals for their daughters to return home after they flew to Istanbul from London on February 17.

Friends Amira Abase, 15, Shamima Begum, 15, and Kadiza Sultana, 16, are thought to have since entered Syria, British police have said.

European governments have called on Turkey to stem the flow of foreign fighters to Syria, and British prime minister David Cameron has urged social media firms to do more to deal with online extremism, saying the girls seem to have been radicalised “in their bedrooms”.

The CCTV pictures, dated February 17 and 18, are from Bayrampasa bus station on the European side of Istanbul, which the girls reached by metro from the airport, Milliyet newspaper said, citing police sources.

They say the girls spent 18 hours at Bayrampasa before boarding a bus to travel to Sanlifurfa, 50km from the Syrian border region controlled by Islamic State militants.

Turkish police are trying to identify people seen in the footage helping the girls at the bus station.

Security forces estimate that about 600 British Muslims have travelled to the region to join the conflict, some with Islamic State.
