The two Viennese girls, Samra Kesinovic, 17, and 15-year-old Sabina Selimovic, whose parents are Bosnian refugees, disappeared in April after saying that they wanted to fight in Syria. 

They first went to the Turkish capital Ankara by plane, and then on into the southern Turkish region of Adana. After that, their tracks were lost.

But they appeared on social networking sites branding Kalashnikov rifles and surrounded by armed men - photos which Austrian police said acted as recruitment posters for young girls.

David Scharia, a senior Israeli expert of the United Nations Security Council's Counter-Terrorism Committee (CTED) said: 'We received information just recently about two 15-year-old girls, of Bosnian origin, who left Austria, where they had been living in recent years; and everyone, the families and the intelligence services of the two countries, is looking for them. 

An Islamic preacher from Bosnia living in Vienna, Mirsad O., known by the Islamic name of 'Ebu Tejma', was allegedly responsible for the radicalization of the two young girls. Authorities say he brainwashed them into joining the jihad. He denies this.

Mirsad O. was arrested for his role in an alleged terrorist funding network based in Austria in November.

It is believed both Samra and Sabina married IS fighters soon after arriving in Syria. The two couples initially lived in the same room but the 15-year-old has reportedly now moved out to a different flat.

Speaking by SMS messages to French weekly Paris Match, Sabina denied claims she was pregnant and insisted she was enjoying life in Syria, where she felt free to practise her religion in a way that she did not in Austria.
