Russian teenager Varvara Karaulova arrived in Moscow from Turkey, where she was caught allegedly en route to Syria to join the Islamic State. The girl will be questioned by Russian police, who will decide whether to open a criminal case against her.

Varvara was detained by the Turkish authorities in the south-central Turkish city of Kilis near the border with Syria last week, when she allegedly tried to cross the border along with another 13 Russians, including six children. The group is believed to have been on their way to join the Islamic State.
