London: 17-year-old Samra Kesinovic was murdered by the Islamic State when she tried to escape from Raqqa and the ISIL.
Despite two Austrian newspapers having published news on Kesnikov having been beaten to death, the Austrian Government refused to comment.
Taking into account, recent reports on Selimovic having been killed in fighting in Syria last year, both young women are now said to be dead.
The girls were traced to Ankara, the Turkish capital, and then went to Adana, near the Syrian border.
The girls' Bosnian parents, who had reported them missing, suspected they had been brainwashed to join the holy war, reported the mirror.co.uk. The parents were Bosnian refugees who had fled from the war there in the nineties.
Samra and Sabina both became 'poster girls' when their photo, showing them holding Kalashnikov rifles and wearing Islamic headbands and surrounded by male jihadists, was used by the ISIL as material to recruit young girls.
They also had another picture online, showing them pointing towards heaven, wearing full Islamic veils.
It was only revealed through a telephone call from Kesinovic to her sister that the girls had joined ISIL. Reportedly, last year, she had written home to say she wanted to return.
An unnamed Tunisian woman, an ISIL volunteer who escaped, reported of Selimovic's murder, according to the Krone Zeitung newspaper. The woman had been living with the two girls in Raqqa.
He has denied any accusation.
