Two teenage girls have gone missing and may be trying to get to Syria to join extremists in the war torn state.
A 15-year-old from Bristol and a 17-year-old from Lambeth, south London, both vanished last week amid fears the pair have been radicalised.
Police are investigating whether the pair travelled together from Heathrow Airport to Istanbul on their way to Syria.
Louisa Rolfe, assistant chief constable of Avon and Somerset Police, said: “We can confirm that a 15-year-old student from Bristol has travelled to Turkey and we understand she may be attempting to make her way to Syria.
“Since she was reported missing by her parents we’ve carried out extensive work to trace her footsteps from the time she left home to her arrival in Istanbul, Turkey.”
The teenager from London, who is from a Somali background, was last seen at around 7am on September 24 when she left her home.
Ms Rolfe said the priority for police is finding the 15-year-old before she crosses the border from Turkey to Syria.
“We’re giving every support we can to her family; we want to find out where she is and encourage her to return safely.”
