A teenage girl who ran away from her Vienna home to join ISIS in Syria has reportedly been beaten to death by the group after trying to escape. Samra Kesinovic, 17, travelled to Syria last year with her friend Sabina Selimovic, 15. The two became a 'poster girl' for ISIS, also known as Islamic State, appearing on social media websites in images showing them carrying Kalashnikovs and surrounded by armed men.
