Missing girls cross border to Syria to join IS
Three missing teenagers believed to be heading to join Islamic State militants are thought to have crossed into Syria, UK police say.
The London schoolgirls were smuggled into Syria from Turkey four or five days ago, the BBC understands.
Bethnal Green Academy pupils Shamima Begum and Amira Abase, both 15, and Kadiza Sultana, 16, travelled to Istanbul on 17 February.
