Samra Kesinovic, 16, and her friend Sabina Selimovic, 15, vanished from their Vienna homes earlier this year.Soon afterwards they posted images of themselves branding Kalashnikov rifles, surrounded by armed men - photos which Austrian police feared were acting as militant recruitment posters for young girls. It is not yet known which one of the teenagers has been killed as the death is yet to be officially confirmed by the Austrian government.Alexander Marakovits, spokesperson for the Interior Ministry, told The Salzburger News: 'We also have this information and have checked it, but cannot say with absolute certainty that it is true. 'But the parents have been informed their daughter could be dead.'Konrad Kogler, Director General for Public Security, also confirmed there were unverified rumours of the death on Sunday evening's ORF program 'In the Centre', The Local reports.The motivations of the two Bosnian girls are unclear but before leaving, they had contact with Chechen youths, and visited a mosque in Vienna's second district.And last week, police expressed concerns that the pair were inspiring their contemporaries after two other teenage girls were caught attempting to flee the country to join IS ranksAustrian media warned several weeks ago that the girls had become the public face for the call to jihad.The fears appeared to be validated with the Austrian Interior Ministry confirming two other girls from Vienna had attempted to flee to take up the call for holy war.Little information was given about the latest pair hoping to join Islamic State apart from the fact that one was 16 and the other was 14 and their parents were apparently from Iraq.Police now want to find out how they became radicalised, and whether anybody had helped them plan their trip to Syria which was apparently set to take place via Turkey - following the same route as the other two girls.The pair were caught when the mother of a third friend who was supposed to be travelling with them became suspicious about the amount of luggage her daughter was packing.
