A teenaged girl from Austria who had joined the Islamic State (ISIS) and whose image was used in ISIS propaganda has allegedly been beaten to death by the militant group for trying to escape, Austrian media reported. Samra Kesinovic, 17, is one of two girls who ran away from their Vienna homes in April 2014.

According to Austrian newspapers Österreich and Kronen Zeitung, Kesinovic was killed when she tried to escape from jihadist-controlled territory in Raqqa, Syria, and return home. Kronen Zeitung cited a Tunisian woman who claimed to have known Kesinovic and her friend, Sabina Selimovic, before escaping herself. The Austrian interior ministry has not yet confirmed Kesinovic’s death.

The two girls are children of Bosnian immigrants to Austria, and at 15 they flew to Turkey, crossing the border into Syria to join ISIS. Soon after, images of the pair, armed and wearing hijabs, began circulating in ISIS social media posts. In some photos, they appear surrounded by armed men.

As early as October 2014, the UK’s Telegraph reported that the girls had changed their minds and wanted to go home. The report claimed they were likely pregnant by ISIS fighters. Austrian officials said they had been contacted by the girls, who expressed a desire to return to Vienna.

Two months later, Israeli David Scharia, a member of the UN’s Counter Terrorism Executive Directorate, told Ynet that it appeared Selimovic had been killed during fighting in Syria.

“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,” he said. “Both were recruited by Islamic State. One was killed in the fighting in Syria, the other has disappeared.” It would now seem she, too, has died, at the hands of the very group she had left her family to join.
